About Quartz Extreme

Mac OS X delivers an unparalleled, graphically rich computing experience. Thanks to the Mac OS X graphics system, the user interface in Mac OS X is fast and fluid.

If a supported graphics card is installed on your computer, Mac OS X uses a technology called Quartz Extreme to accelerate graphics performance even further, and to show enhanced graphical features.

Quartz Extreme-enhanced features include faster window resizing and scrolling, cross-fading when changing desktop pictures (using Desktop & Screen Saver preferences), a cube-rotation animation when switching users (using fast user switching in Accounts preferences), and others.

To check whether your computer supports Quartz Extreme:

  1. Choose Apple menu > About This Mac, and then click More Info.

  2. In the Contents list, click Graphics/Displays.

    If you can’t find Graphics/Displays, click the disclosure triangle beside Hardware.

  3. Note the value for Quartz Extreme.

    If you have more than one display, each may have a different value for Quartz Extreme.
