hugh.

I already posess one mac OS to be installed on a PC. Now which MAc-System-versions would you mac people suggest to be used by a pc-freak who wants to get to know the most important mac systems? I mean installing the mac OS on my newer and also a little older PCs (Pentium4, down to 1, and up to dualcore and quad)?

also, what bootloader to use best? Thx.
