2011 MacBook Pro Graphics Failure
My 2011 MacBook Pro has the dreaded discrete graphics failure. The best description of the failure (and the fix) is here. I now have two bootable partitions on that machine, one has the kernel extensions for the discrete graphics removed and I use it only to fix the NVRAM and main partition after doing an OS update.
