I don't this will be on the Mac for awhile the engine was not designed for backward capabilities, due to the fact that Bioware did not create the engine as well they just licensed it. The only solution they could is make a Wine Wrapper but I doubt that. So I don't really see a bright future for SWTOR on the mac usually most Mac builds are made from the ground up (I.e. WOW) and such there's not many Mac Compatible MMO besides Everquest
