Rating: 5/5 8.0GB (2x 4GB) PC-8500 DDR3 kit for Macbook Unibody late 2008 February 4, 2016 My memory upgrade was delivered within a week of ordering just before Christmas. I was able to install very easily with the on-line instructions and was up and running in less than 30 minutes (actually did not time myself so could have been much quicker).

I upgraded my Macbook from 2GB to 8GB and the performance is great, very little spinning ball!!!

This is the first time I used MacSales but will definitely use them going forward for all of my Apple product needs. Thank you.

Rating: 5/5 Buy this. Now. February 3, 2016 Admittedly, I purchased this product from Amazon, however this was a genuine OWC product that I got. I added the 8 GB upgrade to my computer and it noticeably increased in speed, no longer lagging like it used to when I upgraded from 2 GB. I thought about getting the 16 GB, however I don't do any heavy computing, so 8 GB is sufficient.

Rating: 5/5 Performance transformed January 26, 2016 Upgraded my mid-2010 MacBook from 4GB ram to 8GB. Was tempted to go for 16GB, but read a a forum post that said unless you plan on using Final Cut Pro, 8GB would be plenty. Before upgrading, I had to wait for ages - and watch the beachball spin - for the MacBook to do anything. Now, it's super fast. I did also install an SSD at the same time, so obviously that is a factor. But, combined, I now have a 6 year-old MacBook that performs brilliantly. I had been contemplating splashing out on the new superslim MacBook, but now so glad I didn't. For a tenth of the cost, I have a really good pc and can wait for the latest MacBook to improve before buying. Cost, service and delivery were excellent.

Rating: 5/5 This upgrade brought my iMac back to life! January 25, 2016 I wish I had done this upgrade years ago. I own a 2009 iMac and over the years, it had become more and more frustrating to use, for anything! OWC made the upgrade about as painless as it could be. If you have a slow Mac of any kind, I would highly recommend doing this upgrade as soon as possible! The dividends are worth every dollar spent!

Rating: 5/5 OWC: Always reliable January 23, 2016 I've been a customer at OWC for as long as I can remember. Probably since I had my own money to spend. I bought this RAM for my mom's MBP 2009 model. It worked perfectly. No problems, no crashes, no issues. A great bargain!

Rating: 5/5 So Worth The Upgrade! January 23, 2016 My MacBook Pro (Mid-2010) had been running slowly for awhile and it was getting frustrating. I was nervous to try and do this memory upgrade myself as I know nothing about computers and was afraid I'd ruin mine. However, I was totally wrong. This was an easy process and thanks to the install videos from OWC I was able to upgrade my memory in just a few minutes. I started up my computer and immediately noticed a difference! It's so fast now! I had to come here and leave this review right away. I haven't had a chance to give my computer heavy use yet, but I can already tell how worthwhile this upgrade was! If you're nervous like I was, don't be, and don't hesitate!

Rating: 5/5 Painless process, peace of mind January 23, 2016 Added RAM and upgraded to a SSD for my mid-2009 Macbook Pro. I was super nervous about setting everything up, but for the most part (outside of formatting the new hard drive) everything was a straight shot. Had to write a positive review because OWC really did make it easy and painless. Than you! It's also worth the peace of mind knowing that there aren't any compatibility issues.

Rating: 5/5 How to bring your old MacBook back to life. January 19, 2016 I purchased this RAM, along with an SSD, to update a 2010 MacBook, the old white one. The MacBook was really struggling to run El Capitan, let alone any additional software, and boot up took an age. The updates transformed it, turning it into a modern, useable laptop. The difference between a laptop with 2Gb of RAM reading and writing to a hard disk drive, and and the same laptop with 8Gb of RAM reading and writing to a solid state disk is "chalk and cheese". No more swap use either, there's memory to spare.

Rating: 5/5 This Product is as advertised January 17, 2016 I updated the OS 10.11.2 (El Capitan) on my MacBook 2010. The MacBook had the minimum RAM to run the OS and was extremely sluggish. The system requirements for the new OS recommended double what I had but I ordered this increased memory show the RAM was double the recommended. The OWC Support video led me through a step by step procedure by viewing it on my iMac and pausing after each step. All previous RAM I ordered had been from OWC and just as in the past I received quality and "perfect fit" product. I would recommend OWC Memory to anyone. The Model by Model guide is easy to read & I have never NOT have their memory fit and be recognized by any of the MAC computers I own or have owned.

Rating: 5/5 My 2008 Macbook is again awesome with new RAM! January 16, 2016 After researching the web to find out why my 2008 Macbook has been lagging, I came upon posts that said the RAM could be upgraded to 8GB.. OWC was one of recommended brands and I ordered through Macsales.com. I am thrilled after having received the product within 4 days of ordering online, and having it installed. I upgraded from 2GB to the max allowed on my Mac and am amazed by the difference it has made.

Rating: 5/5 Competitive price. January 15, 2016 For me, the most important feature of this product was the ease of installation. I can't speak to the quality of the memory -- it works or it doesn't, but the instructions given on the site are exceptional. More than anything else, that's the true value of buying from OWC.

Rating: 5/5 This added memory gave me a big performance boost January 3, 2016 My MacBook Pro has to OS X partitions. a 10.6 partition lets me run old software. Another partition runs the latest (El Capitan). Performance with El Capitan was painfully slow. Replacing the original 2 GB with 8 GB has made a fantastic difference. Performance is comparable under either version of OS X. Enhanced dictation previously brought the system to a screeching halt. Now, it's a useful tool.
