Mac Games

Well - I am 0 for 3 with my Mac games. Despite utterly predictable hardware, none of the three games I bought successfully runs on my system. Quake 4 starts, then just mysteriously shuts down, Civ IV gives an error trying to init python, and Battlefield 2142 tells me I'm on the wrong architecture. So the games apparently are just a bit below all the other software, and in fact the hardware. Steve mate, you've horribly failed.
