Rating: 5/5 Best service and product July 28, 2020 It was great to see the price and then you can be assured of the quality too. Straight out of the box it just works and works and what a life changer. Careful reading and I have double the RAM that was initially catered for. But with so much information both by OWC and via their YouTube Chanel - I took the plunge = it works great! Shipping with DHL and the SMS kept me posted all the way to my door! Thank you for it all

Reviewer: norseman
Rating: 5/5 easy to navigate web site made it a breeze to order July 4, 2020 started off not knowing which product I needed for my particular computer model, but was able to easily narrow it down to the specific memory modules I needed for my generation of iMac. A few helpful realtime exchanges with the helpful representative confirmed it. Although I was prepared to wait weeks for delivery (because of the pandemic), the product arrived within a few days. Very satisfied.

Rating: 5/5 Mac sales once again rocked it.. July 3, 2020 I own a lot of macs at home and I always go to Mac Sales for any parts. This time I bought a 16gb RAM for my mac mini (which had 4gb to start with). This made the mac mini super fast (by reducing the swap files). Installation was a breeze too. Highly recommended.

Rating: 5/5 Worked as anticipated June 17, 2020 A long awaited memory upgrade for a MacBook Pro 13 in (mid 2012) non retina finally realized. The machine’s speed improved very noticeably using this advanced replacement, as suggested by OWC memory selector. I still need to replace the HD with a solid state one; maybe a dual one. Bottom line: this computer service life has been extended. The set came certified in a nice packaging

Rating: 5/5 Wow May 20, 2020 My iMac (27-inch, Late 2013) was running so slow and getting the beachball so much that it was virtually unusable. I started shopping for new one but the cost is really prohibitive. I was running with 8 GB of RAM (standard when it was purchased) but saw that the max I could use was 32 GB. I took a $180 gamble and ordered 32 GB of memory. It's like I have a brand new computer. Everything happens instantly when I click it, like it's supposed to. Thank you OWC for saving me ~$1500!!!

Reviewer: BruceP
Rating: 5/5 Old Slow Laptop No More December 11, 2019 My old 2011 non-Retina MacBook Pro had become so slow and unpredictable that I cringed when thinking about using it. A deep system cleaning helped some but I felt a small investment in a RAM and SSD upgrade might be worth it. I replaced the 4 GB of factory RAM with 16 GB OWC RAM and at the same time replaced the 320 GB HD with a 500 GB SSD from macsales. Install was easy with the tools provided. I cloned my HD to the new SSD using SuperDuper!. The first time I powered up, everything was faster. Much faster. After a few weeks of usage, same: everything is super fast. Booting up, waking up, application opening/switching/quitting/etc, everything. It would be nice to know how much to attribute the performance changes to RAM vs SSD but for less than the price of a couple of cases of fancy beer, I'm thrilled to have what is essentially a brand new laptop. Now, my original battery is rather wimpy so maybe an upgrade there is in order.

Rating: 5/5 Saved my 2012 Mac! December 19, 2018 A few weeks ago, my mid-2012 MacBook Pro suddenly shut down and started to beep out the code for a RAM error. Trying to turn it back on never lasted more than a few minutes before it shut down again, and none of the solutions suggested online related to reseating the RAM sticks worked.

This product did the trick! After a 5-minute install, my Mac was back to great working order.

A tip for anyone in a similar situation: A MacBook Pro can run fine on one stick of RAM. Try using each stick individually to see if one still works, and that will help you keep working while you wait for the replacement RAM to arrive.
