I just put Mint on a different 2011 iMac 27”, haven’t done Linux since Yellow Dog. Much nicer experience so far

One of the best they ever made imo

There were no 2013 MacBooks with spinning disks, last year for that was 2012

I just updated a few 2011 iMacs to Monterey using this: https://dortania.github.io/OpenCore-Legacy-Patcher/

They’re a bit more sluggish than they were on High Sierra, but everything works well enough. For some reason I couldn’t get the latest version to work but a previous one worked great (1.5 vs 2.2)
