Rating: 5/5 Mid-2010 model running like new!! January 24, 2020 Could not be happier with this purchase and upgrade from 4GB to 16GB RAM on my older Mid-2010 macbook pro. The site made it easy to identify exactly which product I needed (8GB ram x2), arrived in my mailbox 3 days later (earlier than expected), and the instructional video helped me complete the install in no time (like, 5 minutes max). My machine immediately recognized the upgrade on reboot.

My machine was basically a brick and after a fresh OS install and upgrading the RAM, it's running like new. I'm now using it to run high-CPU usage applications like MainStage and Logic without any issues. Best $75 I've spent in a long time!!!

Really impressed how fast it came to me in Ontario Canada. The other thing that I was impressed with is how well it was packaged to product the memory. Great job overall.

Rating: 5/5 Expanded memory on 2009 13" MacBook Pro October 12, 2019 Like all minimal memory computers, my 2009 13" MacBook Pro really needed more memory to give decent performance. I purchased 8GB of memory from OWC and have installed it. I was very pleased with how going from the stock 4GB of memory to the 8GB made such a very visible difference in the performance of that old laptop.

Rating: 5/5 Very happy musician. September 12, 2019 You guys promised me 7 day delivery and I got it today after just 4 days! Thank you. I installed it and had to check the speed. I gotta say...I am really happy with the upgrade. I had no issues on boot up. I had previously installed a SSD that really gave me great performance. This is icing on the cake with the new RAM. My music programs (Logic, MainStage, and Band in a Box) work much better. It's hard to find good service out here. You guys at OWC are the exception. I will be back soon. Thanks.

Rating: 5/5 Speedy, again! August 6, 2019 When I first got my 2010 MBP it was fast. Then, as time went on, and using my MBP for work and home purposes, I tended to do a LOT of multitasking. As a result, I noticed more and more of a time delay in opening progs, and especially the construction drawing files. This brought new life into my MBP!! It's still going strong today.

Rating: 5/5 16gb The right stuff for 2010 13" MBP June 28, 2019 Learned on another website that my 2010 13" Macbook Pro could take 16 gb of memory so I wanted to upgrade. Bought from them and struggled with it for several days. The chips were OK but just would not work - could only get it to 12gb. Read on another site the OWC memory was the only one that would work for this model. Ordered my two 8 gb modules here, got them super fast, plugged them in and POW - I have 16 gb in my 9 yo laptop. Upgraded to a 1TB SSD drive and this thing just purrs right now. Hope I can get another 4 years out of it. THANKS OWC!!

Rating: 5/5 a good solution for my problem with disk January 21, 2019 A few months ago, I filed an objection to disk quality (120GB OWC Mercury Electra 3G SSD 7MM), which after a short period of installation failed. But after I wrote my remark to OWC and MacSales.com, the company OWC replaced the old disk with a new one in very short time. I take this opportunity to thank the OWC for efficient problem solving and a high professional level and to recommend OWC and MacSales.com to all future customers on this official website.

Reviewer: DuffENator
Rating: 5/5 Ram always helps December 27, 2018 I was given a free 2009 20-inch iMac, 2.66 Ghz that only had 2 GB ram. Wiped it and installed El Capitan, the last OS it could handle, 10.11.3.

Slow as molasses. Painfully slow. Too be expected though. The GPU is old, as is the CPU. Tweaked the prefs to turn off the fancy transparency stuff, but still slow. Just maxing out the ram to 8GB helped immediately. Activity monitor showed before almost all the ram was being used just to run the OS, lol.

This upgrade helped a lot. Also replaced the HD with an SSD, which helped this old machine astronomically. But that's in another review.

Using this old mac as an email server. Working like a champ. Ram helps.

Rating: 4/5 Installation flawless - outcome ok November 6, 2018 The installation of 16GB of ram in my IMAC was flawless. The instructions were excellent. I discovered a fair amount of dust bunny stuff in the compartment and this needs attention. After I closed up the IMAC and turned it on, it booted flawlessly. Then the major question: was peformance better? The answer is a qualified yes. Some of the delay was not improved and may relate to my Cable Service (Optimum) and some may relate to performance issues with Chrome. So the outcome was positive but maybe not the tremendous increase of speed that I expected. No fault of this wonderful company.

Rating: 5/5 Like New October 29, 2018 OWC/MacSales.com was a pleasure to deal with. To make sure I ordered the correct memory upgrade for my IMac, I called and spoke with a tech representative. He checked carefully with me and then re-assured me what to order. The upgrade kit was delivered as ordered. Once installed (which was easy and took only about 10 minutes), the computer worked as quickly as it did when I first purchased it years ago. Very happy with OWC. I already recommended them to a friend and would definitely order from them again.

Rating: 5/5 Simple Upgrade · Great Result October 25, 2018 I just upgraded my MacBook (13-inch, Mid 2010) from 8GB RAM to 16GB RAM. OWC makes it so easy to order the right parts by making sure you select the right MacBook model and ID. In my case, this was a MacBook7,1. I ordered with confidence, they shipped the next day!

When it arrived, I went directly to the Install Videos they provide for my model MacBook7,1 and the hardest part was unscrewing the 8 itty-bitty screws! I was grateful that I had already had purchased my screwdriver kit from OWC years ago.
