Who said you need a Mac to run Mac OSX?
I was able to install Mac OSX Panther on top of Windows XP the other day using an amazing little tool called PearPC. It’s not really a “tool” per se (Mardigan’s a tool) it’s more of an emulator that mimics the PowerPC ISA on an Intel machine. And, as an obvious consequence, running Mac OS X this way is pretty slow– but still usable.
