Applemacanix buys PC versions of these cards, flashes them for use on the Mac, and sells them via eBay. There are three relatively affordable options for Power Mac G4 users (not counting the PCI Graphics model): Nvidia GeForce 6300 and ATI Radeon 97 Pro. The stock card in AGP Power Macs was the ATI Rage 128 or 128 Pro with 16 MB of VRAM. Again, a supported video card might fix this. Once again, probably because the video card doesn’t support Core Graphics.įailing DVD Player, Ricker attempted to run VLC 0.8.6c, only to discover it dropping about 25% of frames.

Front Row: It appears that the program is running, but you can’t see anything on the screen, making it useless.

Again, possibly due to an older, unsupported video card.

DVD Player: No luck, not even with a better SuperDrive installed.

Time Machine appears to require Core Animation. But you can’t get backed up files back, at least not with the older, unsupported video card in his computer. Ricker reports on some things that don’t work on his 1999 Power Mac G4:

The bad news is that some third-party additions to the System can prevent Leopard from booting – Unsanity’s Application Enhancer (APE) tops the list of add-ons – so you should make sure all of your software is up-to-date and may want to (or need to) disable System add-ons before installing Leopard.

The bad news is that the Leopard installer refuses to let you install it on any Mac slower than 867 MHz.
