Huge thanks to iFixit for sponsoring today’s video! As usual you can find all the parts and tools you need for an upgrade or repair project at https://iFixit.com/lukemiani With the new M1 24 inch iMac here for 2021, I thought it would be worth taking a moment to look back at the old 2019 21.5 inch 4K iMac. Specifically, the old design retains a lot of upgradability that Apple has been getting rid of for years now. The last upgradable iMac can actually be taken quite far, so today I’m going to upgrade a 21.5 inch iMac from the core i3 to a core i9!
