Leopard: Single-Layer Install DVD: How To…
October 31st, 2007
The time has finally come when DVD5 (Single-Layer) discs aren’t even big enough to hold your favorite operating system. Which is all well, just more “candy” to drool over, unless you’re in a somewhat similar situation like me.
I’m currently using a 15-inch MacBook Pro (2.4GHz) which I bought in august. My previous machine was a 15-inch PowerBook from May 2004 with a 1.5GHz G4 processor. Leopard installed fine on my new machine you might imagine. My PowerBook though, has some issues with its optical drive, specially when it comes to Dual-Layer DVD discs.
The evening I got my copy of Leopard, I obviously was in all haste to install it on the MacBook Pro. Once done I also wanted to upgrade the PowerBook cause my parents use it every now and then. Okay, I lie. I really just wanted to geek out with leopard on a PowerPC machine too, thats not a crime right? 
To make my life hard though, I’d forgotten about the optical disc problems with the PowerBook. And without any external optical drive, or firewire hard drives at home, my options quickly became limited to burning a Single-Layer DVD disc with only the essential stuff needed to actually install Leopard on it.
This turned out being a bit harder than I originally thought tho. After a few failed attempts, I got it working.
Keep in mind that I’m not an expert on OSX internals or how to custom make bootable discs. Some of the stuff mentioned bellow might not be deadly necessary to make a bootable stripped down Leopard install disc. Its simply what worked for me. Just so you know before you classify me an idiot incase I’m doing something unnecessary 
Also I’m trying to keep it simple so non-geeks find this how-to useful too.
Overview.
What we’ll be doing here, is simply stripping out non-vital data from the Leopard installation disc. This means you’ll end up with a disc without software like the Xcode developer tools, printer drivers and language translations. They are not required to install a working copy of OS X. Once you’ve completed the installation, you can install the removed software from a disk image of the installation disc (more on that later).
Step 1: Create a read/write Disk Image from the Install DVD.
First of all, you’re gonna need at least 12-13 GB of free space somewhere. Then you’ll obviously need to insert your install DVD into your computer. Or if you’re like me and paranoid about optical media. You’ve probably already created a DMG from the install disc for safe keeping on a backup drive. In that case you’ll need to mount the DMG.
Next launch Disk Utility (found in the Utilities folder inside the Applications folder). In the source list to the left in Disk Utility, you’ll see a disc called “Mac OS X Install DVD”, select it.
Next select File > New > Disk image from disk2s3 (Mac OS X Install DVD)…
Disk Utility will now ask you where you wanna save the image. Browse to somewhere where you have at least 8 GB of free space. Select “read/write” as the image format. Name the new disk image “Leopard RW.dmg” and click Save.
Then go make yourself a cup of coffee or do something else to kill about 20-30 minutes.
Step 2: Remove non-vital content from the read/write DMG Image.
Once you’ve created the new DMG, mount it. Now you have a mounted exact copy of the same volume on your original install DVD. Only here you can delete stuff.
Open the mounted volume and start with trashing the “Optional Installs” and “Instructions” folders. Next press cmd+shift+G or select “Go to Folder…” from the Go menu in Finder. In the dialog that pops up type “System” and click Go.
Now you’ll have the hidden System folder from the install disc open. Open the “Installation” folder and then the “Packages” folder. Now we need to trash some of these installation packages which are taking up a lot of space, but are not vital for Leopard to install. The plan is to simply remove all printer drivers, and all language translations.
Here’s the complete list of packages you need to trash:
- BrazilianPortuguese.pkg
- BrotherPrinterDrivers.pkg
- CanonPrinterDrivers.pkg
- Danish.pkg
- Dutch.pkg
- EpsonPrinterDrivers.pkg
- Finnish.pkg
- French.pkg
- FujiXeroxPrinterDrivers.pkg
- German.pkg
- GutenprintPrinterDrivers.pkg
- HewlettPackardPrinterDrivers.pkg
- Italian.pkg
- Japanese.pkg
- Korean.pkg
- LexmarkPrinterDrivers.pkg
- Norwegian.pkg
- Polish.pkg
- Portuguese.pkg
- RicohPrinterDrivers.pkg
- Russian.pkg
- SamsungPrinterDrivers.pkg
- SimplifiedChinese.pkg
- Spanish.pkg
- Swedish.pkg
- TraditionalChinese.pkg
- XeroxPrinterDrivers.pkg
Once you’ve trashed all these files, its time to empty the trash to remove the files permanently from the disk image.
Step 3: Creating the final 4.38 GB Disk Image and burn it to a Single-Layer DVD.
Now we need to create a new disk image with the correct size. Sure, the first disk image we created only has just about 4 GB of data on it, but its volume size is still 7.5 GB. Which means you still need a dual layer disc to burn it.
Unmount the modified disk image you just stripped down. Then we need to create a new 4.36 GB disk image with Disk Utility. I know, 4.38 GB is the limit of Single-Layer DVD discs, I just prefer to aim right below the limit, just incase.
In Disk Utility select File > New > Blank Disk Image. The image format should default to read/write which is what we need. Change the size to 4.36 GB. If you’re using Leopard make sure that Partitions is set to “Single partition - Apple Partition Map”. Save it somewhere you’ve obviously got at least 4.36 GB of free space and name the image “Leopard Stripped.dmg”.
Then go for another, but shorter, coffee break.
Once done, mount the new empty disk image if it isn’t already mounted. In Disk Utility select the mounted volume of the new disk image and click the Restore tab. Drag the “Leopard RW.dmg” image into the Source box, and drag the mounted volume of the “Leopard Stripped.dmg” image into the Destination box. Mark the Erase destination checkbox.
Click the Restore button and wait a few seconds. Disk Utility will report an error of some kind. Select “Leopard Stripped.dmg” from the source list on the left and click the Eject button in the toolbar. Once ejected, click the Open button and it’ll mount again, but this time the volume label should be “Mac OS X Install DVD”. Uncheck the Erase destionation option and click the Restore button again.
Time for a third coffee break.
Once the restore process is complete, unmount “Leopard Stripped.dmg”. Then its time to burn the disc finally.
Personally i used Toast to burn my stripped down disc, but there shouldn’t be any problems burning it using Disk Utility. To burn it using Disk Utility, select “Leopard Stripped.dmg” from the source list on the left, and click the Burn toolbar button. Use any normal DVD±R disc
Step 4: Installing Leopard from the Stripped Install DVD.
Installation is pretty much exactly like normal, except you have to make sure it doesn’t attempt to install any printer drivers of language translations. Those files aren’t there anymore, and if the installer tries to install them, it’ll just commit a pretty suicide.
UPDATE: As Mike pointed out in his comment, if you are performing an upgrade install the installer requires that any previously installed language translations are updated. Which means they can not be unchecked during installation. To get around this, he recommends using Monolingual in Tiger to remove the additional languages before performing the upgrade install. If you go down this path, please let me know how it goes as I’m curious.
Also, it can take a VERY, VERY VERY long time for your machine to boot from this customized disc. My PowerBook took about 25 minutes too boot, all the while just showing the gray apple logo and spinner.
After selecting which disk to install Leopard on, you’ll have a Customize button in the lower left on the installation wizards dialog. Using the customize feature, uncheck Printer Drivers and Language Translations. Then the installation will go on without a hitch.
Step 5: Installing the software stripped from installation disc.
For this, you’ll need a mac which can read the Dual-Layer Leopard disc, just like you did in the beginning to create the disk image from the Leopard disc.
Create another disk image from the Leopard install disc like you did in the beginning. Only leave Image Format on compressed. I’d recommend you name it “Mac OS X 10.5 Leopard.dmg”. This disk image file you can keep as a backup incase you ever loose or otherwise damage your original Leopard install disc.
Then its just a matter of making the backup disk image accessible with the help of networking or an external hard drive to the newly installed Leopard machine. Simply mount the disk image, and use the Optional Installs package to install any/all of the language translations and/or printer drivers you want. You can obviously install the Xcode Developer Tools as well.
Step 6: Uhm…. Enjoy Leopard? Can that even be classified as a step?
Thats it, you should be all set. Now you can play with Apple’s latest toy 
P.S. You probably noticed the screenshots I’ve used here are from Leopard. I simply don’t have a Tiger machine anymore (hehe). Also yes, I’ve installed Windows XP with Boot Camp, partially to test out the new Boot Camp 2.0 (which partitioned my internal drive a lot faster than Boot Camp 1.4), and to play some games those rare moments when I don’t have anything to do.

nice..i’m trying it now…^.^
November 1st, 2007 at 7:23 pm
Just tried it.. but after burning my macbook pro cannot read the dvd image i just burnt, even though mounting the image works just fine…
November 1st, 2007 at 10:17 pm
Sylphic: Have you tried burning the final Leopard Stripped.dmg to a DVD again? Seems to me like something went wrong with the burning, or your MBPs optical drive just doesn’t like the brand of DVD-Rs you’re using. I’ve had problems with specific brands every now and then myself, both with my powerbook, and my mbp…
November 1st, 2007 at 11:25 pm
when i try to restore the rw to stripped it says resource busy what can i do
November 1st, 2007 at 11:32 pm
bobby: Did you unmount the RW disk image before you tried to restore? If so, try unmounting both images, and then mount the Stripped image again and try…
November 2nd, 2007 at 12:33 am
yes thanks that was the problem, i was able to restore to a dvd5 image now i have another problem, the dvd wont boot
dont know why
November 2nd, 2007 at 12:36 am
SIlly question - are you holding down C on boot…?
November 2nd, 2007 at 1:07 am
mmm no i am not holding C
let me try that
November 2nd, 2007 at 1:13 am
bobby: If holding C right after the chime sound doesn’t work, try holding down the alt/opt key instead. It’ll give you a list of bootable devices (could take a minute or two for it to read the dvd). If the DVD doesn’t show there, something must have gone wrong during the burning or restore process to the Stripped disk image. In that case I’d recommend you repeat step 3 from the beginning to make sure nothing’s gone wrong.
November 2nd, 2007 at 1:23 am
woot it works it boot up and is installing now
November 2nd, 2007 at 1:26 am
congrats bobby, enjoy
November 3rd, 2007 at 10:45 am
man i have my new imac i did everything right it shows the grey apple booting but 1:30hrs do the same thing it want go farther…
pls help what can i do? i did try both ways (c) and(alt)
November 3rd, 2007 at 11:34 am
just works. thanks
November 3rd, 2007 at 12:22 pm
acito8010: My best guess is that your iMac’s optical drive doesn’t like the brand of DVD-R media you’re using. I’ve had similar problems with both my PowerBook and my MacBook Pro.
Was the optical drive spinning and reading the disc? You should have been able to easily hear it working away in there if it was.
But I’d recommend you restart from step 3 just incase it wasn’t the disc itself, but still use another brand of DVD-R media if you can. Personally I’ve never had any problems with Sony or Maxell discs.
As I said my PowerBook took about 25 minutes to boot, and from what I could tell it was slow reading all the files from a bit all over the disc that the kernel needs. And it was seemingly taking a long time cause (I could be wrong, just guessing here) the original disc’s data has been laid out on the disc right next to each other. While when i booted off my modified disc, it sounded like it had to read files spread out all over the place and it was taking a lot time for it to jump between the beginning and end of the disc to read a few bytes here and there.
And that was with a Sony DVD-R which have always worked perfectly. I’m scared to guess how long it’d take if I’d used a DVD-R disc which I generally have problems with.
November 3rd, 2007 at 2:35 pm
can i try it use an partition to boot it or it must be a dvd??
November 3rd, 2007 at 3:12 pm
acito8010: No, of course you can use a partition. If you have a big enough partition, you don’t even have to strip down the original disc. Just restore the original DVD/DMG onto the partition. Hold down the alt key while you’re booting and select the new Mac OS X Install DVD volume.
If you do this, I recommend you select to erase the destination when you do the restore.
I would have done this myself for my PowerBook, but as I think I mentioned in the post, my 750GB usb/firewire external hd was still in the post on its way to me, and I wanted a single partition spanning the entire HD of the PowerBook.
November 3rd, 2007 at 3:41 pm
well is something wierd… when i finish with all and is ready to burn on a dvd when i mount the dmg file it have the symbol install os x blah blah and a second file (system) is that correct? and i restore it on a partition and when i restart the laptop i hold the (alt) but it was show up the seond hd…
November 3rd, 2007 at 9:45 pm
ok i did it work on dvd i burn it on an (ASDA) Brand dvd and it works perfect!
thanx alot Jim!!!
November 3rd, 2007 at 10:59 pm
This looks like a nice tut and all, but it won’t work for me. I’m using OS X 10.4, and I can’t seem to delete the Optional Installations and Instructions folders form the disc image. Instead, trash gives me an error saying ‘The operation cannot be completed because you do not have sufficient privileges for “Optional Installs”.’ (or Instructions) The folders and the disc image are read and write, I checked in permissions. What am I doing wrong?
November 4th, 2007 at 1:09 am
lucas: That sounds quite weird. I’m guessing something didn’t go perfectly according to plan when creating the read/write disk image.
But you can try opening the Get Info dialog of the mounted RW volume, and check under the Permissions section if there is a “Ignore ownership and permissions on this volume” setting. If there is, it should be checked in. If its not checked, obviously, enable it. Then try emptying the trash again.
November 4th, 2007 at 11:23 am
I have a problem with the above tutorial on how to install leopard.
I used the same method but placed the dmg on a partitiion. When I get to the Leopard installation screen I uncheck all the printer files but when I come to the language files I can’t uncheck German and French, but I already removed them from the dmg file.
Any ideas on how I can make sure those pkg files (German.pkg etc) aren’t check: so aren’t necessary for the installation (he is giving me an error while installing and I could trace it down in the log file (/var/logs/install.log).
thanks
November 4th, 2007 at 3:14 pm
Had the same problem. Restarted and then I could delete with no problem.
November 4th, 2007 at 5:32 pm
I am having problems with uncheking Language Translations during instalation. Languages appers grey and cannot be uncheked in any way. If I continue, instalation ends saying I don’t have all the necessery parts of software and restarts to Tiger.
Until this, everything I did was strictkly via your plan?!
November 4th, 2007 at 11:11 pm
Pieter & Mat: Are you using English as the installation language? I would guess if you for example choose to use German during the installation process, that language would be required to install. As for French, possibly the two languages share some resources.
If you’re not using English during the install process try it. Otherwise, start over, but don’t trash the .pkg package files for the languages you can’t uncheck during the installation. Even if you leave two languages it should still fit on a single-layer DVD-R disc. My own stripped disc without any languages was just under 4.1GB.
Let me know how it goes
November 5th, 2007 at 12:28 am
i’m having problems with the restore part…
i get a “restore failure” then eject the volume, when opening it again it still opens as leopard stripped and not Mac OS X Install DVD as you say it should…
any help?
ta
tyron
November 5th, 2007 at 12:45 am
tyron: Sounds a bit weird. Try just unchecking the “erase destination” option and restoring it. Then burn it and hopefully it’ll work and be a bootable disc.
Like I mentioned in the post, I’m not a guru when it comes to OSX bootable media creation or such, so all I can say is good luck and hope that it works… lol
Let me know how it goes please
November 5th, 2007 at 4:33 am
For those of you with the issues of Language Translations not being able to be unchecked: This only seems to occur when using the Upgrade installation option.
The installer requires that any previous Language Translation packages that currently exist on the system be updated. You can remedy this by removing those existing language packs using a utility such as MonoLingual (http://monolingual.sourceforge.net/).
After removing the relevant language packs, you should no longer have the uncheckable language pack issues in the installer.
November 5th, 2007 at 8:56 pm
Jim,
I am getting an error message when trying to create the image
“Unable to create “Leopard RW.dmg” - Input/Output error
Any ideas?
Thanks mate
November 5th, 2007 at 9:48 pm
dmarshad: Seems like your optical drive is having problems reading the disc. Or you don’t have enough space to store “Leopard RW.dmg” in the location you selected to save it. Make sure you have at least 7.6GB of free space. If so, check so the disc doesn’t have any dirt or scratches. If not, try using an external optical drive.
If all fails, then I’d be a bit clueless without more information about what exactly is going on.
Let me know how it goes
November 5th, 2007 at 10:07 pm
20 bucks says that story about being paranoid of scratching your original disc is a lie and you actually downloaded al copy of Leopard, then found you had problems booting a DVD-R DL so came up with this elaborate method. Personally I booted it from a USB drive..
November 5th, 2007 at 10:35 pm
What’s your paypal address Dave? lol
November 6th, 2007 at 2:21 am
hi dave,
you said you booted from an usb drive…
did it worked ?
did you just copy the whole dvd content (including system, kernel and so) into the root of the disk ?
November 7th, 2007 at 2:23 pm
hi
when i trying to restore Leopard SW to Leopard Stripped drive in the middle of copying blocks process it shows me restore failure message, and it says: An error (22) occurred while copying. (Invalid argument).
Please help!
November 7th, 2007 at 2:33 pm
Oleg: I’m not sure why it would do this, and the error message itself isn’t exactly that useful. I’d recommend you try to restart the machine, then mount Leopard Stripped again, and restore the “Leopard RW.dmg” file onto the mounted Leopard Stripped volume again.
If that fails, try starting over from the beginning of Step 3 again and create a new Leopard Stripped disk image. Possibly something could have gone wrong with the creation of the blank disk image. If possible, I recommend you create the new image on a different hard drive if possible incase its a physical problem with your hard drive.
Otherwise, only other thing I could suggest, is that you start over right from scratch incase the “Leopard RW.dmg” file has gotten corrupt for some reason.
Good luck, and let me know how it goes please
November 7th, 2007 at 4:41 pm
Jim, thanks for the answer!
Something weird happening with Leopard RW.dmg because it is busy even if Finder or Disc Utility shows no mounted discs. Restarting doesnt help. The last time Ive mounted it by Toast… and had problem Ive described in previous comment. How can I get that file not busy?
Thanks!
November 7th, 2007 at 8:44 pm
Oleg: When you did the restore, did you use the mounted volume from Leopard RW.dmg as the source, or the .dmg file itself? If so, try by dragging the dmg file itself into the Source box.
Otherwise, try restarting from Step 1 and creating a new Leopard RW.dmg file and so on. And if possible, store the DMGs on a different hard drive than you did first time around.
Let me know
November 7th, 2007 at 9:27 pm
is it important to use dvd-r or can i use dvd+r?
November 7th, 2007 at 9:30 pm
patrick: It doesn’t matter if its DVD-R or DVD+R, as long as your burner can burn to the type in question (pretty much all burners do both now a days).
November 7th, 2007 at 9:44 pm
i don´t know what i do wrong, the name of the burn dvd is “boot” and not mac os x ………
November 8th, 2007 at 11:03 am
I’m having the same problem as Oleg. After the “Invalid Argument” error, the image created boots to the grey apple logo but will not go further. I’m on a Powerbook G4 1.25ghz. Btw… can the final image be written to a DVD-RW so I don’t keep making coasters?
November 10th, 2007 at 11:23 am
Zhang: What version of OS X are you running atm? If not the latest, try to update. This seems a bit strange to be honest, have you tried restarting the machine after creating the image and before restoring it? Was Leopard RW.dmg unmounted when you tried to restore from it?
Also, it should work just fine with a DVD±RW disc, if the disc is readable, its bootable
P.S. Sorry for the long delay, the national ISP had some major network problems the last two days (again? yay!).
November 11th, 2007 at 3:33 pm
Hi, I’m having the sam problem here. “An erreor occured during copying (16). (ressource is busy)”
Tried it from scratch, nothing else, same problem.
From that time on, the RW could not be opened again, because it is busy.
There is one point not clear to me in the instructions, maybe you can clarify that: After the first try to recover the image, when i unmount and remount the stripped image (the empty one), and that gets another name, do i recover it to the “Leopard stripped” image, that still is in my list, or do i recover it to the newly mounted “Mac OS X Install DVD”? Also I treid both, both didn’t work, but what would be the reight thing to do?
November 12th, 2007 at 4:18 pm
gram: Have you tried using Disk Utility to unmount Leopard RW.dmg? It sounds to me like Leopard RW.dmg is still mounted when you’re trying to restore from it. Disk Utility will unmount the image automatically, unless something is still using the mounted volume.
Try relaunching finder maybe if you don’t have any finder windows open from the Leopard RW.dmg image. Otherwise try restarting the machine. Also, the destination for the restore should be the “Mac OS X Install DVD” volume under the Leopard Stripped.dmg image, and uncheck “Erase destination”. If the volume in Leopard Stripped.dmg is not called “Mac OS X Install DVD”, restore to the mounted volume of the DMG, but select Erase destination. Disk Utility will give you an error, select Leopard Stripped.dmg from the list on the left and click the Eject button in the toolbar, then click the mount button. Then you should have a volume called “Mac OS X Install DVD”…
Good luck… and let me know how it goes please
November 20th, 2007 at 12:10 am
i couldn’t delete from the image, it says i have no privileges to delete,
please help as i have the image only not the original dvd,
thanks
November 20th, 2007 at 3:35 pm
hamed: Get info on the mounted Leopard RW.dmg volume, and make sure “Ignore ownership and persmissions on this volume.” is checked under the Permissions section. If it is, I’m afraid I have to ask if you created a read/write disk image from the original one.
Let me know how it goes
November 28th, 2007 at 4:34 am
hi, i burned my disc and tried to boot from it, but it wouldn’t work. the computer hung up on the gray apple for about 10 minutes, then restarted. it repeated this process for over an hour with no results. i burned another disk using burn (the first time i used disk utility) and the same thing happened.
any ideas? the mac os x install dvd shows up fine on my desktop, and everything appears normal
November 28th, 2007 at 4:47 am
phil: I’m honestly not sure what’s going on there for you. Personally I’d first try burning another disc with a different brand DVD±R disc just to be sure that the optical drive likes the disc. If you do this, try burning it with Toast if you have it, since I never even tried burning the final disc with anything else *whistles innocently*
If that fails, maybe try starting over from step one to make sure nothing went wrong during the creation process of the stripped image.
If all else fails, try a dvd cleaning disc? lol… As far as I know the install discs boot process will just abort and reboot if there are physical reading problems with the disc right from the beginning. But also, as i mentioned in the post, it took about 25 minutes for it to boot on my PowerBook.
This is honestly the first problem anybody’s posted about here where I didn’t right away have a decently solid theory or something of whats gone wrong, so please keep me posted of how things go for you
November 28th, 2007 at 5:34 am
thanks for your comment
i burned a 3rd disc using a different brand (sony) and i used a slower burn speed (8x instead of 16x). same results. i do not have toast, so i have not tried burning with that. im going to try one more brand, imation. if this fails ill start over from step one.
again, thanks for your help, and if you have any more ideas, please let me know
November 29th, 2007 at 2:51 pm
I can’t get it to change names:
“Once ejected, click the Open button and it’ll mount again, but this time the volume label should be “Mac OS X Install DVD”.”
Ive followed the exact instructions - any tips?
November 29th, 2007 at 3:36 pm
meichow: Did you use the mounted Leopard Stripped volume as the destination, or the dmg itself? Cause if you used the dmg that would explain it. But then, since it does produce an error when done “correctly”, it’s most likely not intended to be used in that way.
If you can’t get it change volume label, just make sure the mounted volume is empty, and then restore Leopard RW.dmg onto the mounted Leopard Stripped volume without erasing destination and keep going from there with burning it. I’m not sure if this will work, but it logically “should” work at least.
Let me know how it goes
November 29th, 2007 at 7:38 pm
Thanks Jim for the very efficient response.
Yes, I tried again following exactly the *mounted* volume Stripped but when i eject and open again, it does not change name: remains as “Leopard Stripped” (mounted volume).
Also FYI, i get the “Could not find any scan information” error when trying to restore with erase ticked.
Any other suggestions? thx Jim
November 29th, 2007 at 8:58 pm
meichow: Try creating new blank “Leopard Stripped.dmg” image, restore to the mounted volume of it with erase destination selected, when it gives you an error, just hit ok, eject the dmg itself in disk utility, then mount it again.
Now, if the volume label didn’t change to “Mac OS X Install DVD”, you can rename the volume manually from the desktop. Then restore Leopard RW.dmg onto the mounted volume of the Leopard Stripped.dmg, making sure that “Erase destination” is NOT checked.
Once done, continue the steps from my article to burn it to disc and see if it’ll work… keep me posted
December 7th, 2007 at 6:58 am
Like Bobby, I receive an error when restoring the RW to stripped. “An error (16) occurred while copying. (Resource busy)” Tried unmounting both but now I cant mount RW without receiving error. When I restart I am able to mount RW but as soon as I unmount and try to restore I get error. Any ideas?
December 8th, 2007 at 1:27 am
bixkid: Are you restoring with the erase destination option checked in? Also, are you restoring from the Leopard RW.dmg to the mounted volumed of Leopard Stripped.dmg?
Worst case scenario if nothing wants to work, try recreating the Leopard Stripped.dmg image. If even that fails try starting over from scratch with creating the Leopard RW.dmg disk image, cause something could have gone wrong with that image.
Let me know how it goes
December 8th, 2007 at 6:37 am
The erase box is check to start then unchecked once the mounted volume says “Mac Install DVD”. Also I am restoring from the Leopard RW to Stripped and still get errors. I will start from scratch and let you know. Thanks!
December 8th, 2007 at 11:30 pm
I think, I’ve solved “resource busy” issue: look into Volumes folder on your system Hdd, remove (under shell) “Mac Os…” symlinks, all of them. It looks like system remembers mounting names and gets confused when two different volumes have the same name. Good luck.
December 10th, 2007 at 9:33 pm
“Now you’ll have the hidden System folder from the install disc open. Open the “Installation” folder and then the “Packages” folder. Now we need to trash some of these installation packages which are taking up a lot of space, but are not vital for Leopard to install. The plan is to simply remove all printer drivers, and all language translations.”
i cant delete it says:
the operation cannot be completed because you do not have sufficient priviledge…
i have check the info of the mounted Leopard RW.dmg volume, “Ignore ownership and persmissions on this volume.” is checked under the Permissions section.
help!
December 12th, 2007 at 6:52 am
jhann: Sorry for a delayed response. Are you sure you selected to create a read/write disk image? If not, create the Leopard RW.dmg image again and make sure its read/write. I’ve done that mistake once or twice myself *whistles innocently*
Otherwise, only thing i can think of is if your user account doesn’t have administrative privileges, that could cause your problem.
If all else fails, i recommend you just try starting over, cause something seems to have gone wrong when creating the RW disk image.
Let me know how it goes please
December 19th, 2007 at 7:00 pm
Hey, everything goes fine for me. It does take some time to boot, but then it passes the grey screen with the spinning bal and arrives at purplish screen with a spacey/starry background. So, it would seem I’m on the verge of install, but then it just hangs there with that background for so long…….
The mouse moves and everything, but that’s it. Did anyone experience this, and if so, how long did they wait at this screen. Please let me know as I’m aching to get this cat on the run…. THANKS
December 20th, 2007 at 1:31 am
Vijjon: How long did you wait with the desktop up and running? For me it took a total of about 25-30 minutes if i remember right before it was ready and asked me for a language. I believe it just stood there with the wallpaper and mouse showing for at least 5 minutes, probably closer to 10.
Let me know how it goes please
December 21st, 2007 at 4:43 am
I got to the space background and it stalled for over an hour. The whole time nothing was spinning, the computer stopped reading from the DVD and it just sat there until I powered it down. Its as if it does not want to load the installer?
December 21st, 2007 at 3:35 pm
Simon: It sure seems odd, but considering these stripped discs normally seem to take up to 5 times longer to boot from than an original disc.
Personally though, I’d try creating a new single-layer install disc from scratch just incase something went wrong with the first one. Or if I had some errands or something to run, i’d boot the machine off the disc before I left the house to see if it’ll be ready by the time I get home a few hours later.
Good luck
December 21st, 2007 at 5:31 pm
Is it ok if on the install disc the “var” etc” and “tmp” are no longer invisible. They appear as visible aliases on my first 8 gb dmg. Is there any advantage to using sparseimage over read/write dmg?
December 22nd, 2007 at 3:47 am
Simon: It shouldn’t be a problem if those symlinks are visible (they’re symlinks to the same named folders /private/. As for sparseimage, like I’ve stated before, I’m not a disk image guru or anything, I simply outlined what worked for me. With that said, from what I know, i believe it should work, but its nothing i’ve tested myself. But go ahead and try if you’re feeling lucky (or bored), and please let me know how it goes
December 24th, 2007 at 8:07 am
I ended up doing it through target disk mode from a DVD-DL disc running in a brand new macbook. None of the SL-DVDs I made would actually launch the installer. weird.
December 27th, 2007 at 7:13 pm
i needed exactly this information!!
thank you!!
December 27th, 2007 at 7:40 pm
Simon: Weird indeed, but then, this isn’t exactly intended use of the install disc, so there’s nobody to *officially* complain to… lol
But you did get it working with a hard drive
that wasn’t really much of an option for me… lol
Namuncho: Glad to be of help
January 4th, 2008 at 4:22 pm
Have anyone experience “looping” while booting the disk. I made to first disk using Disk Utility it booted but didn’t installed correctly because I removed the asianlanguage support file which I was not suppose to. The second time around I burned using Toast and when I restarted I can see the CD at boot selection it loads and kept on restarting the computer back to the apple with spinning wheel over and over again.
January 4th, 2008 at 6:50 pm
Jon: Seems like something went wrong with either burning, or creating the modified disk image. Or it could the brand of DVD±R media you’re using, i’ve had problems with a few myself over the years.
So first of all, simplest thing to test is to burn it onto a different brand DVD±R disc. The more complex solution, is to start from scratch and create the single-layer sized disk image again from scratch. Things can easily go wrong (unfortunately)… lol
Good luck, and let me know
January 16th, 2008 at 12:27 am
i’ve still problems to create the 4,7gb image.
still occures failure in the middle of the restoring…
i think that the sparse image is still too big to get it down to the single layer image. because, if i try to restore the image after the failure occures without the checkbox “Erase destination” the failure occures that the volume is already full!
January 16th, 2008 at 3:31 pm
chris08: Seems a bit odd. Mount the Leopard RW.dmg image, and get info on the mounted volume. Make sure that used space is less than 4.38 GB. If it’s more than that, make sure you empty the trash if you’ve got things in there. If its still over 4.38 GB, you’re gonna have to go looking to see if the pkg files were removed properly. I’ve had some weird stuff happen on rare occasions regarding removing the pkg files. You can give an app called WhatSize a try to see what it finds.
Otherwise, try starting over from step one maybe… lol
Good luck, let me know how it goes
January 24th, 2008 at 2:48 pm
hi, jimeh
I manage to fix the problem bad burn. Now I want to create a backup to DVD-to-DL-DVD. I manage the first time creating it successfully with this tutorial minus the deleting package parts. But now I cant do it again is there a easy way to copy the Leopard Retail to DL-DVD? By the way your tutorial is the only one I made my Leopard working I had to search for my bookmark to your site.
thanks
January 24th, 2008 at 4:27 pm
Jon: Glad to hear it worked for you in the end
I’m not sure i really understand what you mean with the DVD-DL thing, best i can figure is that you wanna burn a backup copy of the full Leopard install disc to a dual layer DVD-R disc. For that however, you don’t need to convert the disk image or anything, just select to burn the unmodified full-sized 7.5GB disk image
Please correct me if i misunderstood what you meant *whistles innocently*
February 7th, 2008 at 1:28 am
I got to the space background and it stalled. The computer stopped reading from the DVD and it just sat there until I powered it down.
How can I solve this problem?
February 7th, 2008 at 3:25 pm
jimbo: How long did you wait before you powered it down? As I stated in the post, it took VERY long for my PowerBook to boot from the disc. So I’d say leave it at least for 30 minutes after the Aurora space wallpaper has shown up just to be sure it’s not just taking insanely long to get started.
Otherwise, best advise I can give, is try burning the disc onto another DVD±R brand (I tend to use Sony or Maxell as i’ve never had any problems with they’re discs). If it still doesn’t work, try creating the disc from scratch incase something went wrong…
Good luck
February 14th, 2008 at 5:23 pm
HUGE problem. Getting half way through the installation and then…”Install Failed could not validate the contents of ‘PodcastCapture’ click restart to try again or choose startup disc to choose another…” Anyway, thought I would just forget about upgrading and use Tiger to boot but the installation had gone too far and only gave me the option of Mac OS X 10.5 so constantly looping and don’t know what to do!. Didn’t backup either so not feeling too great right now.
February 14th, 2008 at 9:31 pm
Macmad: Ouch, thats not exactly what i’d call a fun situation. Unfortunately the only advice i can give you is to try with the same install disc again (and make sure the disc is clean, and possibly if you can, also try it in an external usb dvd drive). If it fails with the same error, you’re gonna have to use another mac and recreate the single layer disc from scratch, cause things must have gotten corrupted somewhere along the way the first time around.
Best of luck to you, and let me know how it goes incase there’s anything more i might be able to help with…
March 2nd, 2008 at 11:51 pm
when i try and delete the packages i amd told “the opperation cannot be completed because you do not have sufficient privileges” and i am loged in as the administrator
March 11th, 2008 at 9:48 am
Regarding fixing the “An error (16) occurred while copying. (Resource busy)”, for me all I had to do is open the Volumes folder.
Dwilk says that “I think, I’ve solved “resource busy” issue: look into Volumes folder on your system Hdd, remove (under shell) “Mac Os…” symlinks, all of them. It looks like system remembers mounting names and gets confused when two different volumes have the same name. Good luck.”, but I didn’t have to do the rest of it after opening the Volumes folder.
For those who aren’t in the know (like I wasn’t), here is how to open the Volumes folder:
In the Finder, choose Go -> Go To Folder (or press Shift-Command-G). In a dialog box, type /Volumes and press Enter. A semitransparent Volumes folder appears in the Finder window. (The transparency tells you that you’ve opened a folder that is ordinarily hidden.) The Volumes folder contains almost all of your hard drives, partitions, and any CD or DVD players. What it does not contain, however, is your Mac OS X startup drive (Macintosh HD, for example).
April 23rd, 2008 at 7:51 am
My final DVD wouldn’t boot. I get the folder with question mark icon for a few seconds, but it eventually boots off the harddrive. I can open the DVD in Finder and can see all the folders in there including the “System” folder. Does the volume name of the DVD need to be “Mac Install DVD”? In other websites explaining this same trick, there is no such step. Or could it be that the original dmg file that I got via bittorrent is really not bootable? Any tips? Thanks
April 23rd, 2008 at 9:19 pm
vedder: This does sound a bit weird. It might be that the original disc Indy bootable, but it could also be that something went wrong during the creation of the Striped disk image.
I recommed you try starting over from step 1 again. Just to make sure nothing went wrong (which does seem to be the problem decently often).
Also, what app are you using to burn the disk image with? Like I said in the article, I used Toast myself, but it should work fine with Disk Utility. However, I never tested burning it with Disk Utility myself. So if all else fails, try Toast if you’re not already using it.
Let me know how it goes
April 24th, 2008 at 5:05 am
Thanks jimeh. I use Toast since my DVD burner is external. My ibook has just a combo drive. I’ve one more question about the final DVD. When you guys insert it (after normal boot up) does it pop up a window with a big logo of leopard and the folders for the PDF manuals? When I mount the original 6.5GB dmg, that pop-up window appears. But not for the final DVD I created.
April 28th, 2008 at 10:33 am
Hey everyone,
I have DL DVD+R’s so I don’t have to take out any of the data. How can I clone the Install DVD. Whatever I try is not bootable. I need to a make a copy that is bootable. Also, it needs to be able to load Apple drivers when used on a PC. I’ve been trying to do this for the past 13 hours, with no luck! NEED HELP!
Thx,

I followed your instructions to the tee until I go to the point of restore. I got the error message when trying to set the contents into Leopard Stripped.dmg. I followed the instructions you gave after the error message, but I still get the error message that it is busy (16) What gives?
June 10th, 2008 at 11:28 pm
Antonio: If I remember right this sometimes if OSX is still keeping some files in use. I’d recommend you try a restart and then try the same step again. If it fails, I’ll look into it deeper to try to figure out what’s going on.
Good luck
June 11th, 2008 at 3:39 am
First of all thank you for all the wonderful help you’ve provided so far. I have been tinkering around with this for a couple of days, and even though I’m frustrated, I’m having a blast.
My problem occurs after the 20 or 30 minutes it takes to boot up from the stripped DVD. I choose a language, choose the install drive (my Mac HD), upgrade option, then I get to the “customize” field - I try to uncheck all of the languages, but many of them are greyed out and checked. I do what I can to get the least amount of things checked to upgrade / install, then when I hit install, it goes through about 10% and then I get this message:
“The installer could not locate the data it needed to install the software. Check your install media or your internet connection and try again or contact the software manufacturer for assistance.”
So I am stuck at this point. Any help would be greatly appreciated.
June 11th, 2008 at 3:57 am
Anthony: There’s been a few others with the same problem. The grayed out languages are cause you’ve currently got those langages installed in the machine already and you’re doing an upgrade install.
I’d recommend you do try doing an archive install.
Sorry, I gotta cut this short. But I’m in bed dosing off writing this on my iPhone… lol… But I’ll have a look tomorrow if I can find something usefu for you.
June 11th, 2008 at 4:16 am
Thank you for such a rapid response!
I’m attempting another route - I’ve deselected the languages in System Pref -> International, and then uninstalled them using Monolingual. Hopefully this allows me to unselect them during the upgrade install. If not, I’ll go ahead with the archival installation.
Thanks again!
June 11th, 2008 at 9:47 am
Anthony: Oh yeah, I forgot to mention Monolingual. I don’t know to 100% if this method works yet tho, so please let me know how it goes
I was half asleep in bed last night when I wrote my previous comment, so I couldn’t think straight for five cents… lol
July 4th, 2008 at 4:26 pm
Hi all!
So, just to add my two cents:
(1) I discovered if you trigger the system option to show all invisible files [using 'defaults write com.apple.finder AppleShowAllFiles 1'] all the ‘access denied’ and ‘operation cannot be completed’ errors disappear. Plus, it makes your job easier.
(2) I also found that if you receive a ‘resource busy’ error while playing around with the dmg’s, just restart your computer [which, while reading the comments, I found out it resets the 'Volumes' folder on your hard drive]
Now let’s see if I can get this working…
July 14th, 2008 at 5:35 pm
THANK YOU so much for this…!! ^__^
I returned the installation DVD few weeks ago because i was broke
(still sealed ,etc) and I decided to download the Leopard instead. I installed it on my iMac and it work perfect (with DL DVD) then i tried to install it on my powerbook, as you can guess.. no luck (since i dont have DL DVD on my powerbook)
then i found your blog.. thank god! i managed to installed the Leopard using your method above and it works perfect.. the instruction is clear and easy to understand. I didn’t encounter any problems whatsoever when I was following your tutorial. Everything is just perfect in one go..!
Because of you, i still have my money.. and i have Leopard on my iMac and powerbook.. hehee.. once again thank you so much.. ^__^
cheers!
September 9th, 2008 at 9:54 pm
I followed your steps to the dot, everything seemed perfect, but I cant burn it on my Powerbook. Power calibration area error. I did download Transmac and burnt it, and it did mount and show it was a Mac OS X installation. However when I rebooted with option held down, it only showed the Mac HD.
I do not know what I am doing wrong, I just got this powerbook and it is my first Mac.
September 11th, 2008 at 10:42 am
km: I’ve never used Transmac, but I’d bet it can’t burn bootable DMGs properly since your’s obviously doesn’t work. So I would go back trying to burn the DMG with your PowerBook either trying a few other DVD-R disc brands (yes, the burners in the PowerBooks are unfortunately sensitive to brands… lol). Or get hold of a external burner which you connect to the machine via USB/Firewire.
Or as a last resort if you’ve got any friends with a mac, ask them to burn it for you… lol
October 18th, 2008 at 6:06 pm
Great tips, many thanks. My original disk was corrupted and this information plus a download got me through a sticky time when my laptop wouldn’t log me in. I recommend everyone to make a back up of their OS when they get one!
October 29th, 2008 at 9:48 pm
Worked great for me… but after a lot of search+pain. Finally, i’ve succeeded doing some force to quit / relaunch finder (ejecting the disk) (not sure the term, this is french version) so the error 16 stopped to pop up saying there is more than 1 volume open with the same name or whatever.
Thanks a lot!!!
November 10th, 2008 at 11:42 pm
This definitely does not work when using the Leopard 10.5.1 install CD. I tried saving it as a read/write image twice to my external FireWire drive, but the language and printer packages cannot be deleted, and instead there is an error stating that I don’t have sufficient priviledges. I made sure that ignore ownership on this volume was checked, and still I can’t delete those packages, and the pencil icon in the top left of the packages folder is crossed out which shows that I can’t make changes. Finally, I decided to try one moore time by saving it to my internal hard drive, and the same problem persists. This guide does not work.
November 11th, 2008 at 11:30 am
Stephanie: I’ve never seen a 10.5.1 disc myself to test this with. However, I think that either something’s whacky with the disk image creation, or you simply need root access to remove the packages.
If you’re familiar with a terminal, you could try manually removing them using the sudo command to gain root access. I don’t recommend you try this unless you know what you’re doing tho, as you could delete vital stuff accidentally.
Other than that, I don’t really have any bright ideas off the top of my head at the moment. Let me know how it goes.
November 14th, 2008 at 1:43 am
hi
got troubles with “Restore” part
when I do the restore for the first time, it says that “Could not find any scan information. The source image needs to be imagescanned/scanned for restore”
guess that’s normal, but what happens next is:
I eject “leopard stripped.dmg”
I mount it again and have the Leopard Stripped image back
then I put it to the Destination line and uncheck the Erase Destination box
but when I press the Restore button it gives out another failure with text “Could not validate sizes - Operation not permitted”
I had the Leopard installed already, but I made a partition from 2 parts to 1 and everything was deleted, of course. Now I try to install it back for 3 days already, trying different ways…
any help appreciated
William
November 14th, 2008 at 11:33 am
William: The scan information error thing is not normal. I’ve come across this problem once or twice myself, it’s pretty rare. But all you gotta do is select Image > Scan Image for Restore in Disk Utility, select the image you’re gonna restore from, once the process is done, try restoring like normal again…
November 14th, 2008 at 3:47 pm
hmmm…
I have done this for several times, it doesn’t help - it gives out another failure “Unable to scan “Mac OS X Install Disc 1.dmg”. (Invalid argument)
also, I have already created another destination image, another install dmg and they still don’t work.
I have the install cd from my mom’s MacBook, but I have already cracked the OSInstall.mpkg, so it should install on my PowerBook without any problem.
but after removing these listed files I get not a 4.38 GB image, but 4.55 GB + that error with scan stuff.
I have already tried to do the same with CCC, but the size still remains too large
what else should I do?
November 17th, 2008 at 11:15 am
William: If you’re using an install disc that came with a MacBook, there could be extra stuff on the disc compared to the standard Mac OS X 10.5.0 retail disc.
I’ve never had a chance to have a close look at a Leopard install disc that came with a machine, as both my MacBook Pro and my sister’s MacBook were bought 2 months before Leopard shipped.
Best advice I can give you, is to dig through the rest of the disc to see if there’s anything else that’s not vital for installation. You’ll have to figure out yourself tho what’s vital or not.
Once the image is small enough to fit within the new 4.38GB image you’re restoring it into, it should work fine.
November 17th, 2008 at 12:30 pm
thanks for advice, I will check out if that works)
November 18th, 2008 at 3:38 am
I tried a number of different ways to remove the files from the disk image, including the terminal, but nothing worked, and I definitely saved the disk image properly more than once. Other files could be removed from within the image, but noting inside the system folder of the image such as printer drivers and language files.
I decided to simply re-save the image in full because later this week I’m getting a new MacBook Pro (the recent discontinued model that is still available) so I’ll be able to burn it to a DL DVD-R then. Again the version of the retail disc was 10.5.1, and I used my 12 inch 1.5 GHz G4 PowerBook with 10.4.11, as well as my dual 1.25 GHz G4 PowerMac with 10.5.5 to save the disc image, but unfortunately it didn’t work with either PowerPC Mac.
November 19th, 2008 at 2:14 am
Everything goes perfectly until I try to install it.
It takes about 30 minutes from boot to get to the Welcome screen (after you pick your language) as expected.
I uncheck the additional language packs and printer drivers. I assume I leave Additional Fonts X11 checked? Anyway, I’m on my third attempt (second disc) and I just know I’m going to get the same error which is…
I click “Install” and whether I choose to verify the disc or not, it always says something along the lines of “Install failed because there was no software found to install.”
November 19th, 2008 at 2:24 am
This time I got..
“The Installer could not validate the contents of the ‘BaseSystem’ package. Contact the software manufacturer for assistance.”
November 19th, 2008 at 3:17 am
Stephanie: Sorry I couldn’t be of much help, but I’m not really sure what was going on for you there. But at least it’s not really an issue since you’re getting a new machine, enjoy
November 19th, 2008 at 3:26 am
Nullus Somnus: It sounds like something went wrong when you were stripping down the image to 4.38GB. I’d recommend you start over and create a new image to try with.
When I was first trying to strip down my disc, it took me 2 attempts I believe before I got it work after I had figured out how it’s supposed to be done… lol
November 19th, 2008 at 5:22 am
I’m trying my first disc again that I made using a similar, but different method than yours (I was reading a different tut before this one) and it seems to be working now. It says there are 17 minutes left in the install.
November 19th, 2008 at 5:51 am
I got it installed successfully. Thanks for the tutorial!
November 24th, 2008 at 8:16 pm
Great tutorial, thanks! I’m just about to make the final preparations on my Tiger system, i.e. moving all the photos and music to my iPod or laptop, and then I’m going to install Leopard. I had it installed before, but my wireless kept cutting out, and it got annoying!
Just a tip, it might confuse people when you say a DVD+R is 4.38GB, it’s not, it’s 4.38GiB, and 4.7GB
November 25th, 2008 at 3:12 am
Ben: I’m glad you liked my tutorial
As for the disc size, they’re technically 4.3772 GB, disc companies say they’re 4.7 GB cause it’s 4.7 billion bytes on a disc. But a KB is 1024 bytes, not 1000 like the disc companies count it just so it’ll sound and look better on they’re boxes… those sneaky bastards… lol
December 15th, 2008 at 2:01 pm
Thank you SO MUCH for this tutorial!
I tried several other explainations on the net but none of them actually worked for me (probably because I tried this on Leopard instead of Tiger) until I found yours. I was already giving it up throwing my Powerbook out of the window. Don’t know what I’d have done without your help!
February 27th, 2009 at 8:04 am
This was an extremely helpful tutorial. Thank you.
I am struggling with the final step. Once rebooting via newly crafted disk, I arrive at the famed 10.5 installation screen (spacey background, cheeky icons, etc) and select my HD as the destination. Then, it checks the installation disc for “irregularities, or something along those lines” and says it is unable to install.
Not sure whats up. Bad news bears.
Any help would be much appreciated.
February 28th, 2009 at 3:57 am
Alright So here is what I did.
1. Insert Leopard DVD
2. Using DiskUtility clone it to a DMG file on my system entitled Leopard RW
3. Take out all the packages
4. Create new Blank Disk image with 4.36GB custom space, yadda yadda
5. It mounts
6. Click restore, drag Leo RW.dmg and Leo Stripped Mounted image, selec the erase disk
7. error pops up, dismount Stripped Disk, click OPEN, it re-mounts BUT does not change its name at all, so i try again uncheck the erase destination, and then nothing.
im using the original 10.5.0 Leopard install retail disc from November 2007
Ugh!!!
February 28th, 2009 at 4:42 am
Hi there!
I’m just discovering this tutorial and it’s very interesting. I’ve been to every steps without difficulty BUT after having the final Mac OS X Install DVD in disk utility it says ressource busy.
Some people here have the same problem?
Can you still help me out Jim, a year later!!?
Thanx!
March 22nd, 2009 at 10:17 am
Unicite, you have to restart your computer and redo the Disk Utility steps.
Me on the other hand have tried booting from the DVD after burning and it never loads in over an hour.
It detects it as a startup boot partition, it even goes to the apple logo and starts spinning. Then you cant hear the DVD spinning anymore, but the Apple logo and loading spinner continues…. for hours and hours.
Whats going on? Anyone have any ideas?
June 11th, 2009 at 4:18 am
At the end of step one you say to make a cup of coffee, i did exactly that and the disc worked….. now i have leopard and enough energy to face the world. your a good man very detailed instructions ( i have a dual layer burner but the discs are expensive)
June 17th, 2009 at 10:34 pm
It worked! It took several attempts to make sure I had the steps right, but it installed successfuly. In step 3, when it said to change the size to 4.36GB, I tried that and Disk Utility kept erroring about the size. So I tried 4.7GB that was listed in the drop down and it restored successfully (I was using Mac OSX Leopard on my iMac). As far as the installation, I tried 3 times before I got it to install (b/c I kept skipping steps). I had to remember to double-click the Macintosh HD to choose “Erase & Install” and I had to remember to click on the Customize button and uncheck the Language Translations & Printer Drivers. Thank you for these instructions! I had burnt OSX Leopard on a Dual Layer disk and my iBook G4 (1.0gHz) would not boot to it. It would blink a folder with the finder face. This option has saved me from having to buy another DL disk as well as not having to use my external backup HD to install!
I have officially went from Tiger to Leopard. Many thanks!
