Rating: 5/5 INSANE performance upgrades January 4, 2018 I swapped out the dual 2 GB sticks in my Mid-2012 MacBook Pro for these two 8 GB sticks. Wow. Instant and consistent performance improvements. Apps and programs open and load quickly each time. No beach ball or bouncing icon at the bottom of the tray. Operations load quickly and nothing lags anymore. Apple rates the MacBook at handling dual 4 GB sticks, but as others have stated, they handle the 8s no problem. It’s like a whole different computer. Well worth the money.

Rating: 5/5 Excellent Purchase December 17, 2017 After installing High Sierra on my late 2013 27in iMac, everything slowed to a crawl because my 8 gigs of RAM just wasn't enough to get the job done anymore.

Rating: 5/5 This Set worked as soon as they were installed December 9, 2017 My first set of RAM cards wouldn't start up with my 2012 MacBook Pro, so I called customer service and explained that one of the cards didn't fit snugly when inserted in the RAM card receiver(s). They asked that I order a new set and send the faulty ones back. They emailed a mailing label and an RMA number and I mailed the RAM back to them. In a couple of days the new RAM arrived. I installed the new cards. They fit nice and snug. I fired up the MacBook Pro and it started as it should. I checked the status and it now had 16GB of RAM. That's that way it was supposed to work. Everyone I spoke with was very helpful and happy to assist in my RAM upgrade. I recorded my 5 piece blues band when we played the next night and the 5 year old MacBook Pro recorded 4 separate 24bit tracks effortlessly. Everyone should liven up their Mac with a RAM upgrade from OWC
