Rating: 5/5 Speed is Good! September 19, 2017 This is not my first memory upgrade from OWC. I have a mid-2012 MacBook Pro 13" that came with 4GB RAM. I upgraded it to 8GB shortly after purchasing it. The installation videos made it absolutely pain-free and fast. I recently purchased an SSD for that same Mac and wanted to upgrade the RAM again while I had it open. A quick and easy upgrade and my "old girl" is fast, fast, fast! My next upgrade for the "old girl" will be a Data Doubler for a stripped raid setup. She's pretty fast now. Then she'll be keeping up with the youngsters half her age. Mmmm, speed is good!

Reviewer: MadcityMacOwner Location: Madison, WI Experience Level: IT Professional
Rating: 5/5 Trust MacSales info, not Apple, when choosing RAM amount! September 3, 2017 First things first-- I have a mid-2012 13" MacBook Pro... all official Apple documentation regarding RAM indicates it supports only up to 8GB. MacSales.com's upgrade tools though suggested 16GB as the max (spread across 2x8 GB DIMMs). 8 GB seemed suspiciously low, and indeed MacSales' info is spot on. Assuming you're up to date on your MacOS X version, it will take 16GB without a peep of complaint. So go ahead and max that thing out! It made a hugely noticeable difference going over the 4GB I already had. My shipment arrived AMAZINGLY fast even with the slowest option--I think it got to me less than 48 hours from placing my order! Kudos to MacSales for that! Only "complaint" is that installation is really a challenge thanks to Apple's super-tiny screws which require a specialized screwdriver. Luckily a friend who works with a lot of obscure electronics just happened to have one that sorta-kinda worked, but none were a perfect fit--it worked, until the very last screw above the power supply, which wouldn't budge. It would be great if RAM purchases for MBP upgrades included an option to throw in an appropriate screwdriver (maybe they do and I didn't notice it?). Anyway, I "solved the problem" by just bending the heck out of my case to create enough clearance for accessing the RAM--on a 5 year old MBP long out of warranty, that I hardly take anywhere, a little crimp in my case was worth it for more memory! A little electrical tape closed the gap just fine. :)

Rating: 5/5 Fast and Easy August 20, 2017 I found the website very easy to see what would fit my imac as an upgrade and the ram was my first choice. Arived well packaged and no hassles. Video tutorial was nice and clear and fitment was easy. My mac runs a lot better now as it was pushed with the original 8 gig. I now have 24gig. Next purchase a ssd.

Customer service team also very good to deal with, very helpful and knowledgable.

Thanks

Rating: 5/5 2 Minute install. Works Great! August 3, 2017 Compatible with my Apple iMac with Retina 5K display - Late 2014, 4.0GHz i7 Model ID: iMac15,1

Received in a well made tamper-proof package Installation fast and easy. Works great, no glitches ---- I tried a memory upgrade from a different company (Crxxxl) at a lower price and it sent my iMac into a tail spin and would not come out of sleep mode without a full reboot. I returned it and went with OWC.

Rating: 5/5 It's been great so far! August 1, 2017 I upgraded from 8GB of ram and there is definitely a noticeable difference. I wouldn't say that it's acting like a new computer again but its definitely worth the money spent on it. It's also very easy to install. I highly recommend this upgrade to anyone looking to extend the life of their computer. Well with the cost.

Rating: 5/5 They finally worked! July 25, 2017 I added two 8GB memory to the already 16GB (2x8GB) originals. I placed them in the empty slots (1 and 3). At start up it gave me the sound of error. I changed the old ones to slot 1 and 2, and the new ones to slot 3 and 4 and it worked. There was no video in OWC page for this scenario.

Rating: 5/5 Great Upgrade, pro service! July 13, 2017 Got the memory pretty fast. Love how OWC packages everything, it had to endure international travel and it arrived perfectly. The upgrade was worth it every dollar, specially coming from a 4gb Ram macbook pro form 2011. After the painless install, everything was running smoother, faster, it felt like a new device. I work on audio production, so Ram is pretty important for loading plugins, so it actually has improved my work a lot.

Thank you for your amazing products and great prices!

Rating: 5/5 MacBook Pro Memory Upgrade June 22, 2017 I should have performed this upgrade when my Apple Care expired. I swapped out 8Gb for 16Gb and my 2012 9,1 2.7 machine is flying compared to the way it used to perform. Easy step by step video directions made this an easy upgrade. My next upgrade will probably be an SSD for just the OS before the next upgrade. Total time to perform the upgrade - 30 minutes.

Rating: 5/5 MacBook Has a Bit of New Life June 10, 2017 I still plan to buy a new hard drive for my MacBook Pro and I know thats where the real performance improvement will come from, but I can tell this RAM upgrade has helped. My applications run a little smoother and things don't hang like they did before when I run multiple apps, some very heavy resource consuming, at once.

Also, the RAM was super easy to install. The instructions in the video were super clear and I was ready to go within 10 minutes.
