OWC Confirms new 21.5 inch Late 2015 Retina iMacs Can’t Accept User Installed RAM Upgrades
I had a hunch I was right yesterday when I researched the new iMacs from Apple for late 2015 – and I wanted to be sure before I posted otherwise, but the way I read the specs on Apple’s technical specs page for the iMacs was that only the 27 inch iMac was upgradable and site sponsor OWC confirms this with a teardown of the Apple’s 21 inch model.

This means that like OWC suggests that if you’re going to want to max out the ram on the 21.5 inch iMacs to full capacity you have to do so at time of purchase.
