That's what I worry about. I think I read somewhere the graphics looked choppy and there were no shadows when running in OS X. Also not sure it can handle the game in itself, even though my machine does meet the system requirements.
I'll think I'll rather save those money for the rockslide of coming games that I want this fall instead, and then maybe err... "aquire" Sims 3 at minimum costs, should the urge to starve, burn and drown virtual people hit me too hard, even though I kind of am a bit against piracy. But then again I'm also quite a bit against EA.
