Useful Tidbits

I am always in need of a certain command or utility and end up searching the Internet for a solution. I’ve gotten tired of it and am starting to collect useful commands and utilities here so that I can easily find them. Of course that means anyone else can find them as well.

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. It is running High Sierra (10.13) latest and runs great except for the graphics, but I don’t use it for heavy graphics work anyway.
