Did a quickie gogely google and it seems that it is abselutely certain that it wont run on Mac as they cant open .exe files at all, which the new update requires. It also seems that even though linux can open .exe files they have a different architecture called ELF, while windows uses PE meaning you should not be able to open on linux either. The source did however mention something called
Wine which should be able to open Windows .exe.
So BIG NO for mac, And No too for linux though if you put the players through an install hell it MIGHT be possible.
