I’ve been trying to learn which affordable iMac would be best to run world of Warcraft classic, but there’s so much conflicting stuff with the graphics cards on iMacs and which older ones can run metal, and I’m just in over my head. I’ve read that any iMac 2012 and later can upgrade to Mojave, but a lot of the ones for sale run High Sierra. If it’s free to upgrade why are they mostly running High Sierra? I asked this on another forum and got banned so I’m crossing my fingers here. Thanks for any advice you could give me.
