Mac OS X for PPC (Mac OS 10)

Yeah, Single_DVD_Leopard means Single Layer DVD (not single quantity as they all Leopard were single quantity DVD) and is a hack with like printer drivers and language translations removed to make a smaller image that fits a "single layer" dvd disc.
Not sure if thisun retains those hidden partitions supposed to be on all os X install discs.

The Single_DVD_Leopard_Install.cdr is not genuine

When nothing else worked when trying to install Mac OS X Leopard onto my PowerBook G4 1.67GHz without the original installation DVD, here's what eventually did: https://blogbriae.blogspot.com/2020/08/install-mac-os-x-from-usb-drive-o... (Yes, I still use Blogger. Stop laughing!)

Let's say I have Mac OS X 10.4 Tiger installed. I want to reinstall OS. Can I install Tiger using the installer from a DVD image without having a real DVD?

Can I use Mac os 10.4 DVD image with Disk Utility "restore" function?

What filing system is on the drive you're saving it to? Are you hitting a file size limit?

Definitely its own page, just like how we don't add Mac OS 9.2.2 compilations that work in previously-unsupported hardware to the main Mac OS 9 page. This is better for keeping things clean and organized, and is easier to troubleshoot (and I'm sure a lot of troubleshooting will be necessary for that one).

But I must say, what a breakthrough. PPC OS X fans in general will be extra busy trying to see what works and what doesn't for months, and maybe even years, to come now, very very happily so.

So... Snow Leopard Beta for PPC has been fiddled with a bit and got to work on a range of PPC Macs. Details in https://forums.macrumors.com/threads/snow-leopard-on-unsupported-ppc-mac...

From that thread, it looks like attempts have been made to upload it here, but they've failed. I've got the "fresh install" copy that should just work; is there a particular place I should try to put it?

Thank you so much for your help! Ultimately, I was able to get it to boot from the single layer DVD instead, and it is now installing from it.

Burning both the 10.5.6 ISO and the 10.5.4 DMG using ImgBurn and PowerISO respectively, on a Windows PC with a known-good drive, produced media that the iBook would read and mount while booted to 10.4, but would not boot from.

Burning them with Disk Utility produced discs that the machine refused to read - spin up, spin down, eject. I tried using three different SuperDrive-equipped MacBooks. All the SuperDrive machines would read the burned media fine, but the iBook would eject it almost immediately.

I did also try the USB method from the second video you linked, after trying several other (simpler-looking possibilities, including boot ud:,\\:tbxi,; however, I found that my USB disk did not show up in the tree of devices, so I was unable to direct the iBook to boot from it.. In fact, the LED on the drive never illuminated until after OS X started to boot from the hard disk (Regarding this, I mentioned that it showed a prohibitory symbol and printed text mentioning ata-6 when I tried; I ended up testing to see if it did the same thing when I directed it to boot from ud with no USB devices connected at all, and it did the same thing.)

So after all, Leopard is installing and I'm satisfied. Thank you again!

@sfp1954 Yes, I'm in the US. I've tried both the 10.5.6 iso and the 10.5.4 dmg. When burned to a disc both mount fine in OSX 10.4, but it will not boot from either of them.

Hello! I'm having trouble booting the 10.5.6 iso, download #32, on my 12" PowerBook6,7 (iBook 2005.)

I was able to burn it to a DVD-DL using imgburn on Windows. The burned disc mounts in 10.4 on the iBook and I can browse it without trouble. I can select it in the Startup Disk control panel. When I reboot the iBook with it set as the Startup Disk, I get only a flashing ? briefly before it boots back into 10.4 automatically.

If I hold C at boot time, nothing happens.

If I hold option at boot time, only the 10.4 install on the hard disk shows up.

If I try to dir or boot or do anything to it from openfirmware, I get an error.

Moreover, I am not able to use download #31. I cannot extract the dmg from the archive - I'm told it's damaged.

Any help would be appreciated!

EDIT: The zip is extractable on OS X, trying that now. I'm expecting to Restore it to a USB flash drive using Disk Utility. A friend has furnished me with instructions on how to boot it if I'm able to do that, and I will report back here if I'm successful.

UPDATE: I was not able to restore using Disk Utility - the option was greyed out. I am now doing it using dd, which I do not expect to work. It is going at USB 1.1 speed for whatever reason so it will take roughly three hours. I will report back when it's done.

UPDATE: I was able to do an asr restore after doing an asr imagescan with --filechecksum (and it wrote at much faster than USB 1.1 speed, which makes me wonder what was up with dd) but it's still not bootable. I've tried several methods of booting from the USB drive in OpenFirmware, but in all cases I get a prohibited screen with the following text over it:

Opening partition [/pci@f4000000/ata-6@d/disk0:3]...
HFSInitPartition: ffbbeb00
Loading HFS+ file: [\\com.apple.boot.plist] from ffbbeb00.
FailToBoot: 2

To me this looks like it's trying to use the Tiger install on the hard disk as the root filesystem and I'm not sure what to do about that. I cannot ls the contents of the flash drive from within OpenFirmware and I don't know how to proceed. It mounts properly in OS X, just like the DVD I burned earlier, which I also cannot ls. (Earlier I was trying to dir, but I know now that it's ls instead.)

I need a 10.4.2. Installation Disc 2 for iMac G5

Hello Gustavo. Glad to hear that fate and you have that model
Final Cut Pro up to version 3 is supposed to be Mac OS 9 compatible, so you should be good to go with that software. All the best and good luck with your installations.

@Gustavo Miranda: Please note that your 1.25Ghz processor/256ram G4 may not be able to boot natively up into Mac OS 9.2.2
G4's above 1GHz tend to be USB 2.0 late model G4 Macs that are only able to run Mac OS 9 in Classic Mode from an OS X installed system (unless user modified). I think that one exception to that rule is the G4 Mirrored Drive Doors (2003) 1.25GHz FireWire 400 model. If that's also your Mac then it should be OK for you to install OS 9.2.2 to.

Welcome, Gustavo.

You can start by using ImgBurn. I believe it also runs under Windows 10. Page description tells you to unzip in OS X, but you can unzip it in Windows just fine too. Just ignore an extra folder called "MAC OS X" that comes with the zip.

After that, you burn a CD or DVD of the image file of the OS of your choice. It can be Mac OS 9.2.2, or Tiger or Leopard. It's up to you. (I recommend OS 9 for the 400Mhz Mac, but your other machines are perfect with any.)

If you have further questions, feel free to ask us.

It IS the retail 10.5.4 DVD. My retail DVD.

The target archive for download #31 should be for the retail DVD for 10.5.4. Instead, however, it's actually a compressed archive which contains Boot Camp drivers. Can someone upload the the actual cdr/iso for the 10.5.4 retail DVD?

@wnlewis: Whether you're talking about the full Leopard images (dual-layer DVD) or the slimmed-down image at the bottom of the download list (single-layer DVD), after you open Applications/Utilities/Disk Utility on your 10.4.11 installation, there should be a "Burn" button near the upper-left corner of the Disk Utility window; if you click that, it should show an "Open File" dialog box, and in there you would just select the image file you want to burn to disc, click Open, insert a blank DVD, and click Burn once it sees the blank disc. That should be all there is to it. I hope this helps.

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.
