Mac OS X 10.6.7 Driver Update

Apple's Mac OS X 10.6.7 system update overwrites any existing Quadro 4000 for Mac or Quadro FX 4800 for Mac graphics driver, resulting in a loss of graphics acceleration functionality, and also disables CUDA (if installed). To restore full graphics acceleration and CUDA functionality to your Mac Pro system after installing the 10.6.7 update, you must download and install the latest Quadro for Mac driver and CUDA software.

The latest NVIDIA Quadro 4000 for Mac driver is available here:
