Rating: 5/5 More Ram For Older iMac June 24, 2018 When I upgraded to High Sierra I needed more Ram in my wife's 2011 iMac. I ordered on line and received the memory in qick time. I looked at the videos on utube and installation only took a few moments. The computer fired right up and recognized the new ram. Great job and far cheaper that a new computer. We are good until the next upgrade by Apple.

Rating: 5/5 I hate myself for not buying this sooner!! June 18, 2018 My Macbook Pro Mid 2012 is SO much more responsive since I installed this 2 x 4gb RAM kit. I can't believe I sat looking at that dumb spinning beachball icon for SO long.... it's been 5 years... ew... BEST NEWS: I haven't seen it since installing the new RAM :)

OWC - thank you for a well packaged item, quick delivery time and an extremely competitively priced product that works GREAT.

Rating: 5/5 Easy to Install and Works Great! June 18, 2018 This was really easy to install — so easy, in fact, that I didn't even use the directions.

The upgrade gave my poor old little Mac Mini a significant performance boost for very little cost. (I went from 4GB to 16GB.)

There were no issues with the product whatsoever, and worked out of the package.

I would recommend this product to anyone in a similar situation as me, where you are suffering performance issues, but don't really want to buy a new system.

The communication here was excellent, the shipment arrived sooner than expected and the follow up was on point.

I will not hesitate to purchase from OWC in the future!

Rating: 5/5 it's great April 17, 2018 2 grad students, each with an older 13" MacBook Pro (model 9,2) that came with 4GB RAM installed. Bought 2 sets of 8GB for them. They easily installed it, and they're both happier. Not as happy as if they'd been bought new laptops, but happy with the increase in speed. If they're good, I may get them each a hybrid disk drive, and that'll make those old laptops feel a lot faster.

Rating: 5/5 Fabulous! April 9, 2018 I am so glad I decided to upgrade my 2012 Macbook Pro from 8GB to the OWC 16 GB. It immediately gave my computer a boost, with breathing room for RAM memory. I have an app which shows me how much RAM is being used and it was topping out with the 8Gig and now with the 16 gig it is regularly showing over 50%, which means I did the right thing. This is a great company - I've also upgraded to the 1TB SSD, both the new hard drive and memory were easy to install myself with the tools which came with the SSD.

Reviewer: 12AX7 Location: Bakersfield, CA Age: 55-65 Experience Level: IT Professional Owned Product: over 6 months

Rating: 5/5 Good deal and works perfectly March 8, 2018 The order arrived more quickly than expected, positive #1. Took all of about 15 minutes to remove the existing RAM from my iMac and install the new modules from OWC, positive #2.

On startup, machine ran short test (maybe 15 seconds longer than normal boot), recognized the increase in RAM and started up with no problems. Checked system information, had 32GB of correct RAM listed for memory. Positive #3.

iMac felt quicker, noticeable but not huge difference as it had 16GB before, but multitasking and program startup both benefitted from the addition. I was able to re-use the prior installed RAM to upgrade an older Mac mini, so this was a win-win all around.

Thanks, OWC!

Rating: 5/5 Fantastic! Money well spent. March 7, 2018 The RAM was easily installed. There was an immediate improvement in my 2012ish MBP’s performance. It felt like I had a new machine. The performance improvement seen after the RAM update removed any doubt about my continuing my upgrade with the purchase of an SSD drive.
