Mac OS X for PPC (Mac OS 10)

I need some help to make a single disk DVD for Leopard. The instructions seem to be missing. I am currently running 10.4.11 and have made a partition for 10.5. How do I convert the downloaded file to a bootable DVD? Thanks for any help.

What version of Toast did you use?
Remember that you don't mount the disk and then copy it.
You simply drag it into Toast and hit the Burn button.
If you mount the image and then try to use the copy function the disc will not be bootable.

When it reboots, hold down the Option key (also known as "Alt"), so that you can manually pick the CD to be booted, or the newly-installed Tiger partition.

Are you sure Lion will actually do you any good in terms of internet access?
Do you have Lion installed on an external disk? i.e is it bootable?
If so you can just attach it to the iMac and boot from it.
Now use "Migration Assistant" (in the Utilities folder) to grab everything from your 10.4 disk.
(probably should back it up somewhere else as well)
Then you can use the Restore function of Disk Utility to dub the external back to the iMac (this will erase the internal disk). Or you can use Carbon Copy Cloner.

I believe to get to Lion as an upgrade you will have to go Tiger, Leopard, Snow Leopard, Lion.
I don't think you can go directly from Leopard to Lion.

The Leopard 10.5.4 disk is here. It has to be burnt to a blank DL (dual layer) DVD.
I also have several Snow Leopard disks. Both full installers and Leopard upgraders.
I'm not sure if they pass the 10 year test - but I could upload them.

Thank you for your help and kindness.
Happy New Year!!

How can I upgrade my powerpc G5 1.8 with 10.4.11 to 10.5.8?
can anybody help me?
Thanks!!

@Jatoba i tried burning the tiger DVD to a dual layer DVD and it worked! Thanks for the help! Anyways i am now trying to burn a Mac OS X Leopard disk and it keeps giving me error "Unable to burn "name.iso." (0xE00002CA)". Tried the 10.5.4 dmg and the 10.5.6 iso and both do the same thing.

Alright, well, from "I only have dual-layer DVDs", my understanding is that you also tried burning 10.4.x Tiger on a dual-layer DVD, which I'm not sure would work.

It's good you are trying out the "single-layer Leopard DVD" download from here, provided you use a single-layer DVD with it. But in case that fails, here is one suggestion:

Try downloading the three 10.4 Tiger CDs (instead of the DVD version) and try burning those onto CDs, and use those instead. I'm not sure if it relates to your problem, but some of my G4 Macs have some trouble detecting DVDs, especially dual-layer ones, whereas CDs are detected all the time.

Also, don't worry, both .DMGs and .ISOs can be burnt correctly onto discs via Windows, with the correct tools and options. For ISOs, the general go-to option is ImgBurn. For DMG, if a Mac is not available, I personally use UltraISO, which is also a free to use/try program. To avoid headaches, whenever I can, I give preference to ISO files, across all platforms.

@sfp1954, I don't recall having any such ZIP issues on Windows, especially for ISOs and DMGs (and any other image file that doesn't require resource forks). On Mac, both the built-in ZIP tools and The Unarchiver also seem to handle everything correctly.

@Jatoba i think because its a dmg my pc didnt like it

I used poweriso and transmac. i tried tiger using poweriso and it didnt work. couldnt read it at all on windows or the powermac. i only have dual layer dvds. thanks @Jatoba

Hi, @papjco. In order for me or others to potentially help you, I have some questions:

- What program did you use to burn the ISO on Windows? Did you use a dual-layer DVD instead of single-layer? (Dual-layer is usually required for 10.5.x Leopard.)

- Did you try ISOs of 10.4.x Tiger yet? They may be burnt on a single-layer DVD, or multiple CDs, depending on the ISOs. It may be worth a shot before attempting 10.5.x Leopard.

Also, just for your own ability to troubleshoot problems with that Mac in the future, I'd like to let you know the dual-processor (DP) Mac you own is an early 2005 model, based on the description and model ID/number (PowerMac 7,3). The late 2005 models were, instead, all either dual-core (DC) or "Quad Core".

Hopefully you'll get your Mac up and running soon!

Congratulations to get such large uploads finished!

The Panther Internal Edition is the full installer for Panther given to Apple employees, it contains additional tools and applications. I believe there is also a CD version of this but I have been unable to locate it.

It should be installable on any machine that supports Panther

thanks, but I was on a "chicken/egg" situation, no blank DVD DL and my mini's HDD was reformatted. I thought I had the 10.5 DVD, but alas no, so the win10 PC was the only way to make the DVD (mind the mini's combo drive does not support DL)
BTW, I found the solution: I d'loaded the 10.5.4 (8GB image) then using TransMac on PC I restored it on a USB/Firewire external HDD, then used that HDD to install on the mini G4

Sure guys the Single_DVD_Leopard_Install.cdr is bootable? I am unable to boot it on my mini G4 (A1103). I imaged on a DVD-R on my PC using the ImageBurn from your site, still on boot (startup) its not recognised.

Didn't have more time than to upload the image, it's something thats requested every now and then since DL DVD's seem to be harder to find, and are a bit more expensive. As usual, all the extras need to be unticked before attempting to install

It'd be fine to get the 10.5.6 DVD as well, if you want to upload it.

I have Mac OS X Leopard Install DVD and Mac OS X 10.5.6. Should I upload this Mac OS X 10.5.6 DVD ? Do you have this already on your page ? Is Single DVD Leopard install.cdr is Mac OS X 10.5.6 ?

After a lot of kernel panics trying to run the installer 10.4.6 (Tiger 4 6.dmg)on my G5 (Powermac 11,2) (Burn a copy on a different system, clone the image to a small partition etc..), the only thing I didn't test was burning a DVD on the G5 burner which has Leopard installed. Went ahead and burned it, then it worked!! Succesfully installed Tiger now..

OS X Leopard doesn't work
Hopefully I didn't burn too much DL DVDs.
The others OSs work perfectly fine.

I burned successfully a bootable Tiger DVD for a PowerBook G4 on a Windows PC this way:

1.: Extract the Tiger_4_6.dmg.zip on a Mac (i used OS X 10.5.8) with the built in unarchiver (don't use 3rd party apps)
2.: Command-Click on the Tiger_4_6.dmg -> Open With -> Disk Utility
3.: In the window Command-Click on the image file -> Convert "Tiger_4_6.dmg"
4.: Now select the destination where to save and the Image Format -> DVD/CD master
5.: You'll get a 3.53GB image file with a CDR extension, which is just a ISO file. So you have to rename it to Tiger_4_6.iso
6.: Now you copy the image file over to a Windows PC and burn it to a DVD-R disc (i used a old TDK DVD-RW @ 2× burn speed) with a decent program (i used Nero 8).
7.: With this method it should boot with the disc flawlessly, i had no problems with the installation. Good luck!

I'm using macOS Sierra.

This is a great library of software.

I have seen to run into an issue though. I have gone through several DVDs and I can’t seem to make my 10.4.6 dmg bootable. I download it, extract it from zip, and then burn in disk utility. When inserting into my iBook, the optical drive never even spins long enough to tell me it is bootable or that a disc is inserted, it just ejects. The optical drive plays normal DVDs just fine though. When reinserting to my daily Mac, it reads the disk as a Tiger install DVD. Any idea what’s happening? I’ve read some comments about the DMG needing to be locked...not sure if mine was locked when I burned.

Thank you

So I have no clue how to make an actual Panther/Jaguar bootable disc. Disk Utility (the new one) says that both sets of images aren't bootable. And I've tried the discs on my iMac G3 and it doesn't restart. Any help would be appreciated!

Firewire must be built in. If you get the machine running again I would start with an earlier OSX (ie 10.2) and try to upgrade from there. I would not run Tiger on anything less than a 400MHz machine.
