I have a PowerCenter Pro 210. its not the fastest machine on the block, nor the pretties, but it is fast enough for what i need. am thinking about getting a new machine though, i don't want to get left behind when OSX comes out. been waiting so long for it.

anyone has any info on this?

I dont think OS-X runs on any Pre-G3 machines, even upgraded 604's and other upgraded machines. =( Hope I'm wrong!

It should run ON 604e machines I think I read somewhere in Mac OS rumors that it will run on PPC's check it out at www.macosrumors.com

If you do an unsupported install, it will install and function just fine. the only thing is that if your machine goes on the fritz, you can't hold Apple responsible for it.
