Rating: 5/5 More RAM August 13, 2016 Purchased 8gb ram to upgrade my wife's MacBook. OWC makes it easy to order and easier to install with all their helpful videos. Next up I will try to put an SSD drive in her computer to speed it up more. Thanks !!

Rating: 4/5 second set worked as expected August 4, 2016 Used this memory to upgrade my son's MacBook Pro, as part of an upgrade which included a new SSD and battery. The second set of RAM sticks that I received works as expected, so far. The first pair of memory sticks I received looked new and perfect, but despite my trying a variety of procedures courteously suggested by OWC tech support, the MacBook would not recognize the memory. Tech support authorized an RMA, and when a week+ later the replacement RAM arrived it was immediately recognized. In my case, I waited for OWC to receive the defective RAM and then ship out a replacement. If you experience a similar failure and are in a hurry, you might want to inquire about the "Advance Replacement" of the "Lifetime Advance Replacement Limited Warranty".

Rating: 5/5 Easy Easy July 24, 2016 I wanted to double the RAM in my older 2010 MB Pro, and the price for 8 GB if memory was ridiculously cheap these days. Easy to install, and definitely a help to have more RAM. I've bought RAM from OWC for a very long time and the quality has always been top notch, never a problem. I would also like to commend OWC's excellent packaging of sensitive products.

Rating: 5/5 Perfect solution for my MacPro. Product, service, international shipping, price plus online installation guidance. Very happy customer. July 24, 2016 As a returning customer, I was sure my expectations would be met but it turned out they were exceeded. The whole transaction process occurred by the book and receipt happened much faster than expected despite international shipping. Online instructions were clear and concise and the product performed as advertised. I am delighted.

Rating: 5/5 good bang for the buck July 6, 2016 After a bit of research, and given my wife's iPhoto situation, I decided to upgrade her Macbook Unibody RAM. From what I read, the difference between 4gig and 8gig is huge and well worth the expense............going to 16gig was too much $$ for the nominal increase in performance versus 8gig. My wife has a large iPhoto library........about 50,000+ photos and hundreds of vids.......needless to say.......iPhoto works MUCH better for her now.

Rating: 5/5 Success!! July 3, 2016 I bought the 8 GB kit plus the 240GB Mercury Electra 3G 2.5-inch 7mm SATA 3.0Gb/s Solid-State Drive to speed up my Mac Book (late 2008). It actually surpassed my expectations, the Mac Book now handles OS X El Capitain as if it was made for it. I won't need a new laptop for quite some time.

Rating: 5/5 Significant speed-up achieved with memory upgrade. June 27, 2016 I was running a MacBook with 4GB of memory, along with Parallels and a Windows XP virtual machine. When I upgraded the XP machine to Windows 10 it really bogged down the machine. So I upgraded the memory to 8GB and my performance problem was solved.

Rating: 5/5 Good qualty RAM upgrade experience June 6, 2016 Had an exciting time upgrading my RAM with RAM from OWC. Good shopping and delivery experience and easy installation. My Macbook mid 2009 is now up to speed with the addition of SSD drive with external case for my old drive. I plan on getting the data doubler as it's a cool hack for replacing your DVD drive space with a second solid state drive. Thanks alot guys OWC rocks! Great deals on used macs also!

Rating: 5/5 Functional as Advertised June 3, 2016 I added this memory to my 2009 (early) iMac with the 'want' to speed up my machine by upgrading from 4GB to 8GB. These memory modules did just that. Installation was quite easy with an available video showing the steps clearly.

I have a bias to be honest. I have purchased quite a few products from OWC and everyone has functioned as advertised and were delivered promptly. Customer Service has been quite professional and helpful when I had questions. This is a fine company to conduct business with and would not hesitate recommending purchases of what ever products that they offer.
