Anyone who had read the thread knows that the game doesn't use an engine that runs on Mac. I'd assume that would be because it uses DirectX, which is made by Microsoft, and doesn't work on Macs. When you buy a Mac you are aware that most games won't work on it, so don't get pissy when there's a game you actually want to play.
Oh, and go back to elementary school and learn how to use capital letters.
