Hi,   I downloaded FMRTE 14 as the front screen says it is compatible with both Windows and OS X, however as it is a .exe file it will not work on OS.   I have read about a way of portioning the hard drive on a Mac so that you can run Windows.  I'm not a very techy person so I cannot make heads or tails of the instructions.   Does anyone have an idiots guid on how to do this? And what are the risks of doing it? And will I need to purchase Windows?   Many thanks.
