On my Macbook. Back in my PC days, I used to have to manually update my video card drivers ALOT due to the many games I played on it. I know that Apple has the update software feature, but I never seem to see any video card drivers for the 9400/9600 chip. Can I update this manually from the Nvidia site? Or trust that Apple will update drivers when they feel the need. BTW, I'm not having video issues on the OS X, but just wondering.
