You can run AutoCAD on your mac with Boot Camp. But, in my experience (since the beta version of Boot Camp), the AutoCAD license breaks. I don't know why. I tried Googling the problem and there is a fix or patch for this kind of thing. But it was ineffective for me. So I am not able to run AutoCAD at all on my mac, using Boot Camp or Parallels.
For experienced users:
I want to try the Portable License Utility but am afraid that the source computer might lose its license. For example, if the original computer (Comp 1) has the license I want to transfer to Comp 2... if the license breaks on Comp 2, then the license will be invalid for Comp 1 forever. I might have to call Autodesk to activate it again.
In the end, I would not buy a mac for use of AutoCAD. I basically, myself, do not use AutoCAD at all because I only have macs in my household. I wish autodesk could make a mac version!
