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.

Reviewer: Kepik Location: San Francisco, CA Age: 25-34 Experience Level: Power User Owned Product: 3-4 months
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.

Rating: 5/5 Easy to install, works great! November 28, 2016 I've purchased memory from OWC a few times, and I've been satisfied every time. Their support videos make the installation a breeze, and the memory is as good and reliable as that costing much more. I definitely recommend it!

Reviewer: redbeard
Rating: 5/5 It's A No Brainer November 14, 2016 What is there to dislike about 32GB of RAM? I purchased this since I work in a graphic arts field where Photoshop, Illustrator, Lightroom and even After Effects can be open all at once. 32GB can easily cover that with the compatible iMac.

Hard to speak about quality and Durability of the product – BUT once installed, I have never had a problem with any OWC RAM!!

Rating: 5/5 My iMac screams! November 8, 2016 Upgraded the memory of my iMac to 64Gb to boost performance when processing video and photos. The difference is amazing. Installation is a breeze! Macsales prices are so much better than what we can get here in Australia. But I would upgrade to first class USPS for an extra couple of bucks. The order took about 6 weeks to arrive via the cheapest option.
