Well basically I'm using a 2011 MacBook Air with Parrallels running Windows XP. I've downloaded the Arma 2 OA demo from Steam to test out how it runs before buying it. However, when I click the play button on Steam, I get this error message Display adaptor does not support format D24S8 for X8R8G8B8 I've tried turning the Hardware accelaration up (was already on full), and have the latest DirextX thingy. Just wondering if it's even possible to run Arma 2 on my Mac? Or is there a simple fix to get it to run?
