Apple has released an Nvidia graphics update which, according to the release notes, is designed to improve cursor movement when using the Apple Mini DisplayPort to Dual-Link DVI adapter with the latest MacBook Air, MacBook, or MacBook Pro computers. Additionally, the 3.2MB update should also improve playback of HD video on the new unibody MacBook Pros with GeForce 9600M graphics cards, as well as older Mac systems using Nvidia’s GeForce 7300 GT chip – namely the original Mac Pro and late 2006 24-inch iMac model.

The patch comes amid complaints from some users who noticed video distortion when using the DisplayPort adapter with various Dell and Samsung displays. The Nvidia Graphics Update 2009 requires Mac OS X 10.5.6 and is available from either Apple’s website or through Software Update.
