Rating: 4/5 Works well, Nice upgrade July 26, 2020 I upgrade my 2013 Mac Pro by adding additional memory The OWC memory is less expensive than the original Apple memory and seems to work equally well. Installation was fairly to very easy.

One mild complaint - their trade in procedure. The check for the memory I returned did eventually show up; just seemed to take forever. When I contacted OWC i was told that checks are issued twice a month. I wish they had told me that on the rebate form. Not a problem, just would have managed expectations.

Rating: 5/5 Speed of Light December 4, 2019 I live in Melbourne Australia and was pleasantly surprised when the order that I placed on November the 29th arrived 5 days later. OSX Catalina has been doing some random reboots since I did a clean install on my Mac Pro 2013 6,1. I tried many things but one day I had the idea that maybe it was low on memory. Since I have upgraded from 16GB to 128GB my Mac has not randomly rebooted one. Thanks OWC for great products, prices and fast delivery.

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: 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.
