From Yosemite to Big Sur and shocked how easy it was

garage sale, late 2013 21.5 inch iMac $30.00. Came with a magic mouse and keyboard so even if the iMac was pooched it would still be a good deal. Perfect chance to try using OCLP and it was much easier to do than I anticipated. Of course it helps that I've been in IT since forever but wow this is nice.
