I have one of the MBP's from 2008/09 that has the Nvidia 9400M chipset in it. I have frequent freezing which is only getting worse and I have learned that the freezing on these machines is related to a bug in this chipset. Supposedly, there was a firmware update/driver release a while back that fixes this, but I can't find it anywhere. When I go to the Nvidia site, I can't find ANY drivers for Mac. I can only find drivers for Windows, Linux and something called Solaris? Anyway, does this mystical driver I read about actually exist, and does anyone know where I can find it if it does? Thanks.
