Rating: 5/5 Works well-Installed easily September 22, 2020 This kit is well put together, everything I needed is there in one kit, I fitted and assembled all of the kit and it is installed and running well on my late 2012 27" imac. All of the instructions worked as they said, what I liked the best is how I was able to get everything in a kit form in one place, and the kit was made for this specific imac, I didn't have to second geuss if it was going to work or not, also like the Install instructions that helped me set up the operating system after I installed all the hardware.

Rating: 5/5 Memmory Upgrade For Mac Book PRO September 20, 2020 The price was right and instructions were clear. Easy install with the video directions. I wish I had only listened to getting the right tools as I tried to make due with a jewelers kit. My Mac Book Pro runs better and I can open more programs with the new memory.

Rating: 5/5 Correct products competitively priced August 23, 2020 I needed to improve the performance of my Apple desktop computer by adding additional memory. Because it is an older model, I was uncertain which products to order.

Using OWC's online guidance I was able to easily identify the correct memory for my Mac. Although telephone support was available, it was not needed.

Using the enclosed instructions, the installation was a piece of cake and the new memory installed memory wors like a charm. I strongly recommend OWC!

Rating: 5/5 The more the memory-er August 22, 2020 Memory is so cheap compared to the cost of a decent computer. Next to replacing an HDD with an SDD, maxing out the memory in your computer is the biggest bang-for-the-buck upgrade you can make. I've upgraded several computers with OWC memory and never experienced a single problem.

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.
