Either way, keep things clean people. I don't want any OS wars here.
Good luck with that... sounds like a difficult ask for the GMC.
Anyway.... to the actual topic at hand:
I completely agree that GM4Mac is overpriced at $40. It's been neglected even since before it was released, and it's had very few updates since then.
I don't use GM4Mac, but I sincerely hope that Yoyo do some kind of stop-gap update for it.
Otherwise all those Mac users will have to wait until The Great Cross-Platform Unification of GM9.
