PowerPC distros prior to version 12.04 have separate 32-bit and 64-bit installers. The only PowerPC Macs that can use a 64-bit operating system are G5 iMacs and Power Macs. Anything before G5 can only use a 32-bit Linux. Starting with version 12.04 the 32-bit and 64. PowerPC was the cornerstone of AIM's PReP and Common Hardware Reference Platform initiatives in the 1990s. Originally intended for personal computers, the architecture is well known for being used by Apple's Power Macintosh, PowerBook, iMac, iBook, and Xserve lines from 1994 until 2006, when Apple migrated to Intel's x86.It has since become a niche in personal computers, but remains popular. Snow Leopard (OS X 10.6) is also the first Mac OS release since the introduction of System 7.1.2 that does not support the PowerPC architecture, as Apple now intends to focus on its current line of Intel-based products. Thus OS X supported PowerPC up to and including version 10.5 (Leopard). We're not only compatible with Mac OS X 10.4 and 10.5, but we also build our browser specially optimized for your G3, G4 or G5, add AltiVec TM JPEG, HTML and WebM decoding acceleration for G4 and G5 Macintoshes, and soup up JavaScript performance with IonPower, our best-in-class just-in-time PowerPC script compiler. One of our four versions is. Apple PowerMac PowerPC G5 Desktops. The Apple Power Mac G5 has several multipurpose ports that can function as interfaces for a wide variety of computer peripherals.

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.

What you'll need

Games
  • PowerPC-based Mac you want to install OS X on by using a USB drive
  • ...USB drive (16GB or more in capacity; 8GB might work, but come on, it's 2020)
  • Second old Mac that already boots Mac OS X Leopard (other versions may work, but are untested. All I know is that my macOS Catalina hackintosh did NOT work)

Part 1: Preparing the disk image for restore

Mac
  1. Boot up your second old Mac running Mac OS X Leopard
  2. Download #31 (Leopard_10_5_4.dmg_.zip) from here and extract the DMG
  3. Scan the DMG for restore using Disk Utility ('Images' -> 'Scan Image For Restore...')
  4. Lock the DMG (right-click -> 'Get Info' -> check 'Locked')

  1. Format your USB as 'Mac OS Extended (Journaled)' using the 'Apple Partition Map' using Disk Utility
  2. Restore the DMG to your USB using Disk Utility, making sure you check 'Erase destination' (open the Restore tab, drag and drop the DMG to the 'Source' field, drop and drop the partition you formatted in Part2Step1 to the 'Destination' field)
  3. Eject your USB drive and plug it into the PowerPC-based Mac you want to install OS X on

Part 3: Installing Mac OS X (okay kids, this is where it gets complicated - mostly copy/pasted from here; follow that if this doesn't work for some reason)

  1. Boot your PowerPC-based Mac into OpenFirmware (power it down and hold Command + Option + O + F while powering it back up)
  2. Run dev / ls and look for the entry with '/disk@1' at the end of it (in my case 'usb@1b,1')
  3. Run devalias and look for the entry with the text you found in Part3Step2 at the end of it (in my case 'usb0')
  4. Run dir text_from_Part3Step3/disk@1:3,SystemLibraryCoreServices (a.k.a. dir usb0/disk@1:3...) and make sure the entry that contains 'BootX' also contains 'tbxi' (if it doesn't, panic!)
  5. Run boot text_from_Part3Step3/disk@1:3,SystemLibraryCoreServicesBootX (a.k.a. boot usb0/disk@1:3...)
  6. You should see a little spinner, then some white-on-grey text, and finally the Apple logo. Congratulations, you've successfully booted your accursed PowerPC Mac from a USB drive! The installation process is the same from here on out as if you were booting from an official Mac OS X Install DVD.
