I have a Mac Pro and I'm using a small Visio tv as a monitor, and when I upgrade to Mac OS X 10.6.3 and up, my display is all messed up. It becomes smaller, the colors are all off, and the audio won't work. It works fine with Mac OS X 10.6.2, and I'm on 10.6, but I need to find out where to find a download for 10.6.2 (or how to fix the display)
