Arghh, L4D won't work on Crossover. Help? :o

[Emmazing]

So basically, first of all I tried it and the menu didn't work.
So I changed the registry and enabled GLSL.
Apparently that should have fixed it but now when I try to start the game absolutely nothing shows up. Help?

Btw, don't ask why I have a mac. It's a personal preference kthx.

Crossover, as far as I know, is DirectX 8 only. L4D on the other hand is Dx9 and 10 only. So TF2 works on it, but L4D doesn't.

When I played on crossover it showed up, but wouldn't play at all. Too laggy. Good luck trying to play anything other than TF2 with crossover, it's complete shit IMO. Get bootcamp.
