Upgrade 2012 iMac 21.5" RAM
I know that it is extremely hard to get to the memory and hard drive on the latest iMac (ungluing screen, etc). I've always thought iMacs were hard to upgrade and have never done one myself. I have used authorized Apple repair shops to do upgrades, so my warranty has never been voided.
Is that possible? Could I go to one of those shops, have the HD upgraded to a 3TB drive and get some more RAM in there without voiding the warranty? Has anyone attempted this?
Thanks!
