hey just wondering whats different about a mac and pc? i read somewhere that the coding or instructions mac uses to tell the cpu what to do is different than the pc, maybe that was referring to the IBM cpu's, but i'm not sure? Second since my macbook uses the intel core 2 duo, don't i really have a notebook that looks like a mac but has pc parts inside of it? i have to admit the mac os (10.5) overall operates better than any windows os i've tried...so since i have a intel core 2 duo cpu i shouldn't have troubles installing win xp or would i cause of the EFI? If anyone can answer my questions please do so, thank you.
