What you don't have on the Mac Audiophile drive you can copy from the Win Audiophile, you will just need to convert the wma style demos to m4a unless you have a default media player on Mac that will play wma, there are many that will do that.
The Win Audiophile drive works on Mac with a few modes like the RealTracsk/Library folder change to RealTracks/LibraryM & RealTracks/Direct Input/LibraryM
