[QUOTE="harryb2448, post: 1757098, member: 42497"] Your problem is not the gfx card being 64bit, but the EFI being 32bit which means it will only run natively up to Lion OS X.7. Of course you can consider turning your Mac Pro into a 'Hackintosh' using various kext changes, but be warned you do rish turning it into a door stop. [/QUOTE]
