A friend of mine has an old 2012 MacBook Pro which he wants to give to his mother, if it can be made operational again. It was nearly dead on arrival, but I managed to get it running and and install High Sierra. I am now using OpenCore to install one of the newer macOS’, which is not officially allowed by Apple for a mac this old. I believe in the right to repair, so of course the newer OS’ should be able to work on older macs. Good stuff. Tech is fun.
