Nvidia has released what it calls “a critical” update to the Mac drivers for its GeForce GTX 285 and Quadro FX 4800 graphics chip. The driver update is needed to maintain Mac OS X kernel compatibility, and will affect users who plan to update to Mac OS X 10.5.8, according to an Nvidia spokesperson.
Both cards are made for Mac Pro systems. The GeForce GTX 285 is offered by Nvidia manufacturing partner EVGA. It was released in June. The drivers are available for download from EVGA’s Web site. The latest Quadro FX 4800 drivers are available from Nvidia. The Quadro FX 4800 is a workstation-level graphics card offered as an optional add-on from the Apple Store.
Nvidia strongly encourages users of either graphics card to install the new drivers before attempting to upgrade to Mac OS X 10.4.8. As Macworld posted this article, the current release version of Mac OS X was 10.5.7.
