Today i got this message for the first time from the new NVIDIA System Preferences pane that a new driver is available. I couldn't find this update on their site as a standalone- this could be the first direct update for users of the NVIDIA Web drivers. NVIDIA Web Driver 313.01.02f01 http://www.nvidia.com/object/macosx-313.01.02f01-driver.html How to Install the Web Drivers: In order to flag the alternate drivers on a CustoMac, you must install the package and also add the flag manually to the chameleon.org.Boot.plist. For Chimera bootloader: 1. Open Finder 2. Navigate to /Extra/org.chameleon.Boot.plist 3. Open in TextEdit 4. Add nvda_drv=1 to Kernel Flags as shown: Example Usage: Code (Text): <key>Kernel Flags</key> <string>darkwake=0 nvda_drv=1</string> 5. Save and reboot You should be on the new NVIDIA drivers.

If you aren't having any issues, do not install- the native OS X drivers work great for most people.
