MacOS X 10.6.4 on Mac Pro kills OpenGL - stay away

After installing the MacOS X 10.6.4 Update Unity3D (which is OpenGL-driven) kept crashing (as soon as OpenGL is initialized, the whole screen starts flickering) and freezing the system in the process (I run it on a 2008 MacPro). After investigating a bit I found out that it is a problem caused by the latest MacOS X update (10.6.4) and Parallels Desktop (which I use to run Visual Studio).

As I need Unity and Parallels (i.e. Visual Studio) both at the same time, I had to downgrade by re-installing OSX from a Time Machine backup.

I spoke to the Apple Support Hotline and they confirmed this to be a bug in the 10.6.4 update. They recommended downgrading to the last version of the OS.

Just putting this out there for anybody who might have the same problem.
