OWC memory is specifically engineered for compatibility with your Mac. We start with the highest-quality components, and then create memory to the exacting speed, capacity, and programming specifications of nearly every upgradeable Apple computer. The result is JEDEC-compliant memory that’s a perfect fit for a faster Mac.

Your Mac: Happier For Life

OWC memory is built to the highest quality standards and is backed by OWC’s lifetime advance-replacement warranty. That means if you have issues with your OWC memory, you won’t need to wait and return your upgrade to receive new memory. Instead, we’ll ship you replacement memory right away so you can get your Mac back up and running in no time.

Memory That Goes Further

We’re laser-focused on helping you get the absolute most from your Mac. So we developed the OWC MaxRAM certification program to test the true memory limit of each Apple computer. We found that most Macs support more memory than the official factory maximum. With OWC memory, you can truly max out your Mac with up to double the factory-supported limit.

It’s the OWC Difference.
