ArmA 2 Free for Mac OS X! :D.
So, finally, ArmA 2 for Mac! Tested on Snow Leopard (10.6).
Remember though, this is the FREE version of ArmA 2, not the paid version... :3.
This is the 1.0.1 Version, which fixes the no startup error. So do NOT download the old version! Ah well, i might have the old version deleted anyways so, uhm, yeah, but download this version!
