Rating: 5/5 Great product with excellent features June 5, 2016 The product was received in great condition relatively quick after ordering. The process of ordering was very efficient and effective. I am very impressed with the excellent level of costumer service and as a result I will purchase from OWC again in the future. I will also recommend OWC to persons seeking the products that the company sells. The products are working very well so far. I also like the videos on the MacSales.com Web Site that provide instructions on how to remove and install the items that OWC markets.

Rating: 5/5 Great memory at a great price April 5, 2016 The speed of my mid 2011 iMac is unbelievable with the upgrade to 32 GB of memory over Apples 16 GB as Maximum. MacSales has great products at a great price and ordering and delivery is fast. Customer service is great and they are knowledgeable about Apple products.

Rating: 5/5 Despite what Apple says, 32GB of RAM works! March 31, 2016 I was a bit hesitant to order this kit since Apple states that the July 2010 iMac Pro only supports 16GB of RAM, but I figured I'd try it and if it didn't work, I'd just return the RAM.

Sure enough, after I installed the RAM, it shows up as 32GB on my machine! Works fantastic and has significantly increased the amount of work I can do at once on my machine (heavy number crunching in Excel, opening massive images in Photoshop, etc.)

Also, it was great that I could send in my old RAM and get a rebate on it. :)

Rating: 5/5 It's good to be the king February 20, 2016 Back in 2011, I never would have thought I'd need more than 16GB of RAM for video editing, but after tacking on audio engineering, 3D modeling effects, and a whole slew of other plugins, I realized I had to make the leap. It was totally worth it though. It feels so great when the computer is faster than I am in my workflow again.

Keep in mind what processor you have, as I'm glad I went with the i7 because this much memory feels like such a luxury. The speed isn't as important in this case.

Since my OWC 16GB kit is almost 5 years old now and without any issues, I'm sure this kit will be just as reliable.

Rating: 5/5 The Finishing Touch on my Mid 2011 27" I7 iMac! November 1, 2015 The original iMac Apple Hitachi HDD died. I decided to upgrade the iMac with an OWC Mercury Extreme 480GB SSD and a WD Black 2TB HDD. Using OWC cables for the SSD and for the HDD installation, coordinating the process with OWC videos, the installation went smoother than I expected. I created a Fusion Drive using the SSD and HDD. I decided to do a clean install of the Fusion Drive using El Capitan. Then dragging my projects from an external HDD and downloading Apps from the Apple App Store to restore my apps and files, instead of using Time Machine. Now my Mid 2011 iMac feels like a new computer. The finishing touch was using the 32GB of OWC RAM to finish the upgrade. Right now everything is like a new Apple Factory Fresh iMac. Let's see what is happening a few years from now.

Rating: 5/5 Upgrading Memory Good Investment February 26, 2015 My iMac27 was being taxed with only 8 GB of RAM when I began to scan all of my photos and slides in a project that would digitize all of them for preservation. I decided after reading several articles online that upgrading the amount of RAM would help the Adobe photo programs do their jobs faster. OWC advised that my iMac would easily accept 32 GB of RAM with no problems, so I finally went that route (selling my old RAM on eBay). There was a noticeable improvement in processing, especially of digital slides and large RAW images, proving this was worthwhile. I have had no problems with this RAM, but I like the idea of OWC's warranty if something does fail.

Rating: 5/5 iMac 2010 i7 with 32GB of RAM - YES! December 18, 2014 Finally, a solution to my poor old Macs memory handling dilemma.

I can now operate more efficiently with the added memory ceiling that 32GB provides.

Multiple Parallels instances is no longer the major P.I.T.A. that it was :)

Rating: 5/5 Exactly what I needed. November 18, 2014 I purchased this from the web site which helped me find all the correct info about my computer and helped me pick the right hardware for my upgrade. A big bonus was installation instructions and installation videos, I am not a geek but did this upgrade in about 10 minutes with tools I had around the house. Excellant service, handling and fast rebate on exchanged memory chips. I would buy again from this company in the future.

Rating: 5/5 32GB in my iMac OMGWTFBBQ?! August 11, 2014 OWC's website let me in on the little secret that my iMac could be stacked with 32GB of RAM instead of the published 16GB limit. Obviously I had to order 32GB of RAM and make it happen. RAM arrived quickly, packaging was awesome and now my 2011 iMac never runs into any memory issues. Can't wait to purchase an SSD from OWC to complete the makeover!
