MacBook Pro wouldn't accept RAM upgrade.
Last month I tried to upgrade my Mom’s 2012 MacBook Pro with this RAM - Crucial 8GB Kit (4GBx2) DDR3/DDR3L 1600 MT/s (PC3-12800) SODIMM 204-Pin - CT2K4G3S160BM. It would run for a bit but then crash and never figured out why. The attached picture is the specs for her Mac. I’ve searched all over google for an answer and can’t figure out why it failed.
