Just a side thought (and it's certainly not meant as a slam to Mac owners, I have one too) but with all the awareness that Markus works alone on this game and the recent discussions on the V6 release, it's a bit amusing that the suggestion of a Mac version comes up
The guys do have it right, however. eLicense is not compatible on a Mac and to be honest, I'm sure Markus has not had the time to investigate Virtual PC. This is another one of those things that might find its way into the mix at some point - but not now
