Typo? There is no Mac port of SWTOR. It won't even run on Wine (Linux or Mac). (Well, a few claim to have, but it involves patching and recompiling Wine and massive workarounds and still there are issues.)

But back to ARR, Cider > Wine > no Mac port. And even a native port can introduce its own bugs and performance issues, so there's no automatic win there.

For capability, it's generally Windows >= Mac > PS3. (So many Windows computers sold only have built-in graphics, if any, and Macs at least come with some graphics, so there's a little overlap. And though less powerful, all PS3s can play ARR.) For numbers of gamers, it's PS3 > Windows > Mac.
