Hi guys, here are a couple of quick questions for you and your experience: 1- I want to install Windows on a Mac ... I am thinking of maybe buying a mac pro somtime next year ... or mayber just install Windows on my current iMac. If I do install windows on my current iMac and get a virus ... will it spread to all my HDD ... or will I be able to just format the Windows part of my HDD and not my Mac OS part if things go bad ? 2- I am thinking of using my current iMac (1 year old) for doing 3D CAD (Computer Aided Design) Will it be enough ? Or will I be going for a Mac Pro after testing it ? (a have 2 gig of RAM right now) 3- Will my current iMac be able to handle Windows 64 bit ? if so ... Vista or XP do you recommend ? (again my iMac is a year old). I am not into gaming, just doing CAD into Windows. Thanks again guys !
