Can you send me detailed results for these tests (i.e., the shader you ran, the results on these machines, the hardware config of each machine)? I'm collecting results for an internal bug report to the Apple OpenGL driver group. Your data would really help them understand how to fix it, and hopefully which drivers are the highest priority.

If anyone else has useful results on Mac, that would be helpful as well.
