    Rating: 5/5 Great service & best quality parts April 11, 2019 My MAC Pro arrived there Wed. morning and I received it Thursday morning! Works great! Passed Apple Diagnostic tests. Had a 10 Core processor & 96 GB memory installed. All my questions answered and issues solved before I sent unit in by Sarah and Lucas. Both were knowledgeable, helpful, pleasant and thorough. I told them I was under some time pressure, hoping to get it back early next week, not the next day.

    I'm impressed with everything about the Turnkey installations they OWC does, and the people they employ. Can't imagine letting anyone else work on my machine if OWC will/can do it.

    Rating: 5/5 Great Product October 25, 2018 Bought it with a 2nd hand 12-core upgrade for my 2013 Mac Pro for the long way down the road. Easy Installation, no other procedures required for the RAM part afterwards. Now my Mac Pro has all the ram that it can't even use up for my works. Might feel pricey, but totally worth it down the road.

    Rating: 5/5 Saving Money In The Long Run... July 30, 2018 I have a Mac Pro that I use for work in my home office. I run Sierra and 4 virtual machines, Windows 8, MSSQL Server 2012, Infor EAM, and Maximo EAM. The machine was stock other than a 1TB SSD that I put in right after I bought it. The machine really struggled to run OS X and 1 VM together. I replaced the factory 12GB of ram with 64GB, and WOW, what a difference. I can now run all 4 VMs simultaneously with ease. Once I throw another 64GB (machine max is 128GB) of RAM, it should really scream!! I have purchased other things from OWC and have had no issues. If anything ever happens, they stand behind their products!!

    Rating: 5/5 With 128Gig I can rule the world! November 29, 2016 Little early to say since I just installed it but install was easy. No problems as yet. If it hasn't failed yet, it probably won't. That said, I have bought other RAM upgrades from MacSales and have not had a problem

    Rating: 4/5 Best third party memory for Mac Pro out there. July 3, 2016 I would definitely recommend OWC RAM modules. In fact I would recommend not buying the Apple's OEM RAM just based on value and expansion capacity. Order the least amount of default RAM possible then swap out for OWC RAM. That's what I did and I am pleased with the product and decision.

    Rating: 5/5 OWC 128 GB upgrade to Mac Pro 6.1 August 24, 2015 When I purchased the upgrade RAM of 128GB for my Mac Pro 6.1 I received excellent technical support from OWC, The product arrived very quick on my house and I installed the memory according to OWC procedure. When restarting my Mac I was surprised about the increase in responses for all my applications, start up times where in some case half of what I had before (64GB). I am very happy about the decision to buy the product from OWC. Very responsive support and a very good product for my Mac.
