im running a 2 GHz intel core duo mac mini. i tried crossover games with this game and what happens? lags like crap. so i put it in windowed mode, but it freezes. so i restart my computer. now when i click launch team fortress 2 it just flashes a white screen and crashes. and thats with -novid on. without it i get to see that super cool bald dude then a few logos then it crashes when it gets to the game. im using the trial and so far not pleased.
