Simon Leopard doesn't require an Intel machine. It requires a G4 867mhz, i have had it running on a G4 400mhz,

Ugrade From: Simon Graham <[EMAIL PROTECTED]> Date: 30/09/2008 23:51 Hi Simon, I don't know how you are going to get Leopard to work even if you update to a G4 chip, for reasons Bruce suggest. From what I here Leopard is even more demanding of Altivec and requires the Intel chip set. But if you do go ahead and upgrade the chip and the OS, please keep us informed. I'd be interested to know.
