21 21.5-inch iMacs do not have user-accessible RAM “slots”

IMacs RAM

Apple computers, especially notebooks, are less and less customizable. Once purchased, it is difficult to add more RAM, increase storage, etc. Like the MacBooks Pro with Retina display, the new iMac brought a much thinner design than the previous one (80%), also compromising its customization a little. The 21.5-inch model no longer allows RAM access; in the 27-inch model it is still possible, as we can see in the technical specifications of the product. (Cult of Mac)
