Rating: 5/5 It's hard to run out of memory with this RAM upgrade January 22, 2016 I run numerous memory-hogging programs simultaneously on my Mac, so it helps me to have lots of RAM available. For instance, I can have several browser windows open while I'm working on a Final Cut video project, producing podcasts using one of my audio editing tools, or designing graphic images using Photoshop. In addition, I often run Windows in a virtual machine environment using Parallels. Having less RAM available at any given time requires my Mac to rely on swap files stored on the internal boot drive, which is not as responsive as physical memory. Installing the memory chips was straightforward and easy as the OWC tutorial video make them out to be. OWC also has an attractive exchange policy, and I took advantage of this program by mailing the two 4 GB RAM cards that I had bought earlier from the firm. Within a few weeks, I received a rebate check in the mail. If your Mac has 8 gigs of RAM or less and you work on a lot of multimedia projects as I do, then you may want to consider ordering this upgrade product from OWC.

Rating: 5/5 Too Easy. Macbook pro recognized the additional memory - plug and play. December 18, 2015 Too easy. OWC install video was very good for a person with limited skills. Buy the $5 installation screwdriver set as I didn't have a screwdriver small enough to remove the back cover. Macbook pro (21103) recognized the additional memory right away. Memory was fully compatible. I put this off for a month or so but should have done it earlier. Too easy. Use a dryer sheet and wipe your hands for anti-static protocol. Start to finish about 10 minutes. Too easy. Don't hesitate, you can do it. Traded in my removed memory and got a check from OWC in about a week, Used the new shipping packaging to return the removed memory.

Rating: 5/5 More RAM = More stuff December 15, 2015 I have a Mac Mini with a fusion drive and with 8 GB it booted in about 8 seconds, with the 16 GB Ram upgrade it boots in about 5 seconds. Everything opens quicker and I have more things open at once without any slowdowns. Don't forget the REBATE for the old memory! It's great to be able to recycle the old memory and get a few bucks for it too! Very pleased with the results.

Rating: 5/5 easy install, great for speed December 14, 2015 In Apple’s world of hard-to-install upgrades, adding this RAM was pleasant exception. As easy to install as advertised, and a nice performance boost for my MacBook Pro. Though Apple only advertises 8GB as the maximum, this 16GB upgrade works just fine.

Rating: 5/5 Memory Upgrade is a Snap November 26, 2015 The OWC website makes it easy to figure out exactly how many slots your Mac has and offers numerous appropriate upgrade options. Memory chips are shipped quickly. Instructional videos make the actual install easy, even for a novice. Chips removed get sent back to OWC and your rebate is mailed. It has been a pleasure dealing with OWC on the memory upgrade for my Mac.

Rating: 5/5 Rock Solid RAM - Rock Solid Price October 3, 2015 As a Mac computer tech, I've been buying my RAM & hard drives from OWC for as long as they've been around. And that's not just hyperbole.

The RAM I bought for my new 27" iMac 5K Retina will last long beyond the life on this new Mac. How can I say that? Because every stick of RAM I've purchased has worked form day 1, on my computers, and on client installs as well.

Always a fair price for a quality product. And you can't go wrong with their support. From install videos, to phone support, I always get the info I need.

Rating: 4/5 iMac Memory Upgrade Kit September 28, 2015 I needed a memory upgrade for my Late 2012 27" iMac to give the iMac a bit more 'room to breathe'.

I did the search around the net to compare products and prices and although it ended up costing me a little more I decided to go with OWC. I had ordered memory upgrades from OWC previously so I was reasonably sure that the iMac would be 'happy' with the new chips.

The iMac has been running with the new chips for a while now and so far there hasn't been a single problem.
