Upgrading your iMac with more memory is one of the easiest ways to get better performance from your machine. And just like the original 27-inch iMac with Retina 5K display, a memory access panel on the rear of the Late 2015 model ejects via a button, making the memory upgrade even easier.
In this installation video, we show you how to easily install up to 64GB of OWC memory in a Late 2015 27-inch iMac with Retina 5K display.
