Hi Karl, I have not tested it myself but I have heard from a few people recently that MoI is working for them using Parallels on a Mac.

There was one recent forum post here that mentioned it:

Just make sure you are using the most recent 4.0 version of Parallels - older versions did not necessarily allow for programs to access 3D display functions but that seems to be handled much better in Parallels 4.0 now.

Windows XP home edition is fine for running MoI.
