Rating: 5/5 Great product!! March 2, 2017 Worked on my late 2015 27" iMac with no problem. I doubles my memory from 84GB to 16 GB. I didn't want to leave the original memory in the mac since it was two different brands. It probably wouldn't have had a problem but my experience told me to stick with one brand of the exact same kind. Works beautifully!!!!!

Rating: 5/5 Quality RAM, Excellent Performance January 22, 2017 I was between ordering 32Gb Crucial or OWC RAM for my new iMAC. I opted for the OWC based on the positive reviews and the cost being a few dollars less than Crucial.

The product arrived very quickly, was well packaged and the RAM was a perfect fit.

I have yet to put the RAM through much more than normal use, but the speed of the iMAC went from very fast to noticeably faster.

I'd certainly purchase more OWC RAM based on my experience thus far with the product.

Reviewer: MacDaveinSactown
Rating: 5/5 Excellent Upgrade January 22, 2017 I bought a new iMac with the standard 8 GB of RAM. I bought another 8 from OWC almost immediately, rather than buying it from Apple. I've used OWC in the past and I couldn't be happier. The products and customer service are outstanding. Installation was easy. OWC had written instructions and, of course, there are many 'how to' videos on YouTube. I really wish Apple hadn't made the decision to solder RAM to the logic boards in their newer laptops and Mac Mini. I would love to be able to add RAM to those as well.

Rating: 5/5 The simplest memory upgrade ever. January 12, 2017 I decide to upgrade the memory in my iMac. Reviewed what was available for my model and bought the memory set, 2 x8 gig, bringing my total to 24. Opening the back and installing was a couple of minutes and back up and running. Never disappointed with anything from OWC.

Rating: 5/5 Does what it is suppose to do January 2, 2017 I added additional memory to be able to run virtual Windows machines and additional memory for Final Cut Pro on my late-2015 iMac.Since adding the memory a year ago I haven't had any memory issues. Adding the memory to the 27" iMac was very easy and cheaper than buying the memory from Apple.

Rating: 5/5 Works GREAT....but December 13, 2016 Initial pair of RAM was faulty and had to be replaced, but OWC was quick to get an RMA issued out. The replacement worked like a charm for a good 3 months. Unfortunately, I started getting freezes/crashes that were RAM-related issues. Tried running a thoroughly RAM memory test which kept giving my iMac kernel panics. OWC was quick to issue me another RMA. I'm sure the product works and electronics are always faulty. The fact they are quick to issue me another RMA is great customer service!

Rating: 5/5 Great upgrade... December 5, 2016 Cheap compared to Apple prices and thankfully fully compatible with the 17,1. Makes a huge difference if you are a power user / app developer with multiple browser tabs, development tools, simulators, photoshop, etc running simultaneously. Big difference is no more compressed memory compared to my old 32GB iMac which is more significant than you would think. Switching between apps is instantaneous and app startup is also very quick.
