Graphics card compatibility for Mac OS X is a difficult subject. Some graphics cards (especially AMD Radeon cards) are supposed to work out of the box for Mac OS X, but of course, problems happen. Most graphics cards require additional drivers. If your NVIDIA GTX 460 graphics card isn't displaying Mac OS X at full resolution, then this tutorial offers a possible solution, by using the official NVIDIA drivers for Mac OS X 10.6.8, NVEnabler, and the 32-bit kernel for Mac OS X.
NOTE: This method is outdated. The Galaxy GTX 460 works out of the box with the newest versions of Chameleon and Chimera bootloader.
The following solution is only confirmed to work on the Galaxy GTX 460 768 MB, with the Gigabyte P67A-D3-B3 motherboard (my current configuration). However, anybody with similar parts and a similar problem should feel free to try this fix.
1. Install the official NVIDIA graphics drivers for GTX 4XX cards on Mac OS X. This by itself should work for most people; however, graphics card compatibility is a fickle issue, and what works for one person might not work at all for another.
If you're running a version of OS X lower than 10.6.8, you can fake your system version and then install the official drivers. To fake your system version, check out my post here.
2. Install NVEnabler, which is available at OSx86.net (registration required). This is a graphics driver for older GTX graphics cards, but it works wonders for my GTX 460.
