re: MacIntosh versus PC
I did it for a guy in my office who needed autocad to run on his mac. You need to buy a program called parallels. It costs $80. Then you need to have a windows disk to install from that is not proprietary. Dell disks don't work as I discovered, so I ended up buying a new copy as well.
It wasn't hard, and once the OS is in its just like windows except some of the F buttons don't work the same and that sort of nonsense. I'm not a mac guy so that was a little infuriating, but luckily I'm not the one using the machine.
