Those of you who are Mac users may have noticed that Apple released the 10.6.7 OS X update earlier today. For Mac Pro users who have installed an NVIDIA Quadro 4000 for Mac in their systems, installing the update will overwrite their existing graphics drivers. The driver in the update does not contain support for the Quadro 4000 for Mac. Once we were informed by Apple of the release of the update, we initiated the posting of new drivers to the NVIDIA website for OS X. We expect that these drivers will be available on our website within 24 hours. Quadro 4000 for Mac users may want to decide whether or not to delay updating to OS X 10.6.7 until the drivers are posted tomorrow.
I apologize for any inconvience this delay may cause our users.
