21.5-inch iMac Ram Upgrades.
Memory is not removable by users on iMac (21.5-inch, Late 2012), iMac (21.5-inch, Late 2013), and iMac (21.5-inch, Mid 2014). If the memory in one of these computers needs to be replaced, Contact Us.
When we say not removable by the user, we mean that No ram door is on the back of the iMac that allows you to upgrade the ram in about 5 minutes, instead, you have to remove the glass, and the logic board….. don’t forget to purchase the adhesive strips ($20)
