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.

Rating: 5/5 Excellent for my late 2008 aluminum MacBook May 20, 2016 This upgrade along with a new hard drive has completely revitalized my computer. The videos on the website were especially useful in helping me replace the parts myself. I feel like I saved a lot of money buying here and doing it myself.

Rating: 5/5 Removed the Mid-2010 MacBook Bottleneck May 5, 2016 I upgraded my mid-2010 MacBook Pro 13 inch, which came with 4GB of memory and which was dying under the weight of the new OS X operating systems. A completely easy installation. It gave me a chance to clean out dirt and crud that had settled inside the machine. An immediate and impressive gain in performance. No more hanging pinwheels when navigating the web.

I opted for the 16GB package. I could have got by with the 8GB upgrade. Now the machine is WiFi, disk and processor bound. I cannot take full advantage of the max memory because of the other constraints.

My advice. Upgrade 2X from OEM config. Going 4X is diminishing returns.

On the service side, OWC was GREAT! Nice online chat with a tech to confirm purchase. Fast shipping. Product well packed. This is an excellent outfit.

Rating: 5/5 Where has this been all of my life??? April 28, 2016 I had a mid-2009 Macbook Pro that I hadn't used because it only had 2GB of RAM. I had been contemplating to get the newest Macbook Pro or Macbook Air, but I ultimately decided to give my old MBP some love.

This arrived earlier than expected! When I opened the package, I wasn't being careful enough and dropped one of the chips. I panicked, but it was fine. Installation was incredibly easy with the video tutorials.

Wow, the speed! I can't wait to upgrade my MBP to an SSD as well later on.
