Hi, are you the same poster as this Steam discussion thread?

Sorry for the hassle I strongly suggest getting the latest drivers for OSX directly from NVidia's website - sometimes OSX updates do strange things like break OpenGL in strange ways. Graphics card manufacturer drivers usually sort these things back out again.

If that doesn't work, I'll start asking you for logs and other things to help us figure out what's going wrong.
