Ok...off we go to a first post as a new member and a new MAC convert. I'm trying to get everything set up on the mac pro to start using it instead of my old PC. My Mac came with Fusion and Vista Ultimate installed but I haven't registered it yet. I want to take my main drive out of the PC and put it in to the Mac and use Fusion to go back and forth until I'm comfortable with the Mac. The drive is not an SATA and I have XP Pro on it which i would rather keep it than try using Vista with some of my old apps and hardware. So first things first, is this possible and where to I find info on how to procede. Thanks in advance!
