MacPro NVIDIA Quadro FX 5600 Not Supported - Arrrrgggghhhhhhhh!
Quartz Extreme required.
iMovie requires a graphics card that is compatible with Quartz Extreme. One or more of your graphics cards does not support Quartz Extreme.
Simply amazing...the high end graphics card with two monitors does not work.
