Absolutely NO support of NVIDIA quadro 4000 for Mac on OSX 10.6.7 Update
I'm owner of a Mac Pro (westmere dual CPU) with a REAL GRAPHICS CARD!
...a "PNY NVIDIA Quadro 4000 for Mac"
After updating the Mac OS X 10.6.7 update
then all my NVIDIA graphics drivers/features went up in smoke!
- Monitor ICC color profile did not work (all to bright/whiteish OSX GUI)
- All webbrowsers tilted in all Flash driven websites,
because of GPU accel. in Adobe Flash Plug-in. (had to disable Flash)
- Adobe Premiere Pro CS5 Mercury Playback Engine did not work
I was lucky enough that I have used the primary Display port on the graphics card, if I had used the secondary then I would not even be able to start up the Mac Pro!
So I do not think it was a good update on that part!
Isn't Mac's about everything JUST WORKS
or have they got some Windows deceases!!!
So how I see it is that Apple is at WAR with NVIDIA!
Just like they are at WAR with Adobe.
I could manually install the old NVIDIA Quadro 4000 driver by doing a "Show content" at the driver package. Then installing each of the tree drivers and do a Restart. then my NVIDIA Quadro 4000 came to life again.
24 hours after the OS X 10.6.7 Update NVIDIA released a new updated NVIDIA Quadro 4000 driver compatible with OSX 10.6.7
Any ATI Radeon graphics cards is NOT supported with GPU acceleration in
Adobe Premiere Pro CS5 video editing application.

And the NVIDIA GPU acceleration in Premimere Pro CS5 called,
"Mercury Playback Engine" is simply geniously made!

Here is a great demo of what the NVIDIA GPU accel. can do on a Mac Pro:

...A Mac Pro is for a PRO Graphics Card, ... that's a NVIDIA card!!!
