Rating: 5/5 Great set of 4 memory units, revived my iMac July 10, 2020 I was wondering whether I should trash my old iMac from late 2009. Then I decided to try to move it to Linux and upgrade a little bit, so I bought these 16 GB (4x4GB) and an SSD and now I have an old new iMac, which works great with Linux and delivers performance, which I never experienced with Mac OSX before.

If anyone decider to upgrade memory with these units, my recommendation is to also get "DIY Bundle 1.0TB OWC 3G SSD and HDD Kit for Late 2009 - 2010 iMacs" or the 2TB one. They are bringing a new life in your iMac and you don;t have to recycle it.

Rating: 5/5 Exactly what I needed for a 2010 Macbook Pro 7.1 July 3, 2020 Running 4GB of Ram in the year 2020 can be a bit underpowered at times. Making the change to 8GB made a HUGE difference! It's especially noticeable when running multiple tabs or apps. It breathes new life into an old system. I wish I would've done it sooner, and it was incredibly easy to install. I highly recommend this product, and this website in general!

Reviewer: evelyn
Rating: 5/5 Extended life of my 2009 27” MAC July 3, 2020 The early 2009 27” MAC started having frequent whirling ball issues. Doubling the RAM purchased from OWC solved that problem. The 2009 is not equivalent to the newer models but with the doubled RAM and some care to get rid of useless files it works just fine. Thank you OWC for your fairly priced good quality products and you excellent, friendly tech support too.

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!!!

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!!
