High Sierra is finally losing support from Apple (starting in Nov 2020), and I thought I’d give a go at upgrading my mid 2011 21.5” iMac GPU so I can run a supported OS. I installed some extra RAM a few years ago (going from 4gb to 20gb). This would obviously be a more involved task, but while I’m at it, I may stick an additional ssd in there.
I had an Nvidia K2100m graphics card arrive this week, just need to go pick up some thermal past and a few specialty bits.
I also found my spouses 2007 MacBook from college while cleaning/organizing our basement. The screen doesn’t want to display, but I was able to power it on. This may be a good candidate to tinker with assuming I can get the display working again.
