Last week, I wrote that the OS X 10.8.2 Supplemental Update released by Apple contained a modified IOPCIFamily.kext file, which led me to speculate that the update might contain a fix for the kernel panics that have been dogging me and other users with Mac Pro computers featuring multiple NVIDIA GT 120 video cards with monitors connected to them.
Sadly, I have to report that, this morning, after five days of running OS X 10.8 with the 10.8.2 Supplemental Update and with the normal kext files, I had another kernel panic, with the same symptoms and the same kernel panic log information. So my conclusion is that the OS X 10.8.2 Supplemental Update did not fix the problem.
One kernel panic in five days is not so bad, but it’s still one too many for me. I have now re-implemented my hack with the IOGraphicsFamily.kext file from OS X 10.8.1, and we’ll have to see see how it goes.
