With previous versions, I used to keep track of machines that LeopardAssist was confirmed to work on. I've since come to accept that it's less clear cut, and some machines work while others don't. So the "Known Compatible" list has been scrapped. However I have tested LeopardAssist on the following machines with success:
- Power Mac G4 QuickSilver (Original, not 2002 or 2002ED)
- Power Mac G4 Digital Audio
- Power Mac G4 Sawtooth
- iBook G4 (800MHz, October 2003)
LeopardAssist worked when run on OS X Panther and OS X Tiger on the same hardware.
Unfortunately LeopardAssist is only capable of clock frequency modification - it doesn't install any additional kernel extensions or modify any system files. "Unable to find driver for this platform" suggests that OS X is unable to locate the correct kernel extensions for the hardware. I haven't had the chance to look into this myself though as all my machines have accepted Leopard without modification. Even once it's resolved, I wouldn't be sure that LeopardAssist could correct it since it would depend on modifying Leopard's system files after installation, which would depend on Leopard being bootable so LeopardAssist could be run... and so on.
One more thing I need to mention is this line in the "Read Me First" document (Step 2 of the LeopardAssist setup assistant):
I haven't tested LeopardAssist on any machines with a processor upgrade card, but I included this line after receiving an email from someone using LeopardAssist 2.1 several years ago with a Powerlogix processor upgrade card. After running LeopardAssist, the machine would no longer boot. I can't exactly explain the reason for this, and I never found out how the issue was resolved. Since machines with processor upgrades are already likely to meet the minimum requirements for OS X Leopard, I can't recommend running LeopardAssist on those machines.
