Rating: 5/5 Excellent Products November 27, 2016 I just recently upgraded to 8GB of ram and, was previously running with 4GB's.It would appear that my MacBook Pro boots up a little bit faster but, the main difference I find there is less beach-balling. It still happens but not as much as before and I also have the added advantage of more memory. About 2 months ago I installed 2 SOLID STATE DRIVES in a 27" & 20" iMac and this has increased speed and, they operate a lot more smoothly. (This is the way to go). When I can afford it I will be increasing the RAM in my 27" iMac as I have already increased the Ram in my 20" iMac to 8GB (max) I am looking to increase my 27" to 32GB (max). Everything I have purchased from this Company works .(not like some others). I can highly recommend this company.

Rating: 5/5 Significant Improvement to MBP5,3 November 26, 2016 My old (June 2009) MBP 5,3 only had 4 GB RAM and a fried 320 GB hard drive. OWC rep was very helpful in guiding my choice of SSD replacement. Replaced HD with a new OWC 480 GB 3G SSB and then 2X4GB RAM. After reinstalling OS 10.10, WOW. All installation was very easy. Way to go Mac Sales!

Rating: 5/5 Best purchase I've made this year! November 25, 2016 Definitely a before and after success story. My mid 2009 13” MBP had become tediously slow and unresponsive. After looking for a solution online, I found OWC. For the price of the RAM it was worth giving it a shot.

Easy to order and easy to install. I’m usually all thumbs at trying to fix things nervous that I will render them useless, but with the help of the install videos it was literally a snap. It took me less than 15 min. for the process of installation.

I did have to buy a set of precision screwdrivers for less than $10 to open the chassis of the MBP.

My MBP now works great. This upgrade saved me a lot of money from having to buy a new laptop with features I didn’t need, and lacking features I wanted. The OS, various programs, the connectivity and the disk drive are everything I need and want from a laptop.

Thanks OWC

Rating: 5/5 RAM that meets or exceeds specs November 8, 2016 This isn't the first time I purchased OWC Ram, it's performance meets or exceeds Apple specs. I've mainly been getting the max Ram for the different Mac's that we have in the family that are getting to be 7 - 10 years old so I can beef it up to run the new OS. I have never ran into a problem other than my daughters mac mini (late 2009) which is suppose to take 8G but would not boot up with both 2x4 installed. It worked fine when using one of the 4G and the original 1G. I tried both 4G and they both worked so I know there was no problem with the RAM I received. I did contact support and they were very helpful and offered suggestions. There were a couple of things I did not try yet but will when I have time. As of now the mac mini is running fine on 5G of RAm and OS X. As for the product I cannot find any reason not to use it and will purchase again for any future RAM upgrades.

Rating: 5/5 Performs like OEM November 6, 2016 So I was looking for an inexpensive RAM upgrade for my Mid 2009 Macbook Pro which has 2 GB when I purchased it brandnew. I normally use it for web browsing and some MS Office application and it works fine until I installed Adobe Lightroom. I went to an Apple store near my place to check the price of 8GB RAM. Obviously the price was crazy and am not willing to spend more than my budget on my 7 year Macbook which By the way, Im just waiting for the release of the Macbook Pro with Touch Bar which will replace my current. Searched online and OWC came up. Read the reviews and all but positive. The website was very helpful in guiding which procduct is compatible for my macbook. Their Sales Support was very responsive and helpful thru chat. After Sales Support was reassuring when I didn't get my product which I thought 7 days to ship from US to the Philippines (my mistake for not reading the duration part. Up to 45 days but it came ealier than that. I opted USPS) After installing it and using it for more than a month now I'm very pleased with the results. Very happy with OWC. Sales and After Sales support are Amazing. One of the best customer service experiences I've had. Am placing another order SSD this time.

Rating: 5/5 Don't be tempted by lower prices November 3, 2016 I originally upgraded the memory in my MacBook Pro with non-Apple DDR3s. They began to fail three years later, and were replaced with these on the advice of a senior Apple certified technician. Good advice! They've run reliably since, and you can't beat the OWC warranty on OWC products.

OWC sells products from other manufacturers. The OWC warranty does not apply to such products, though they will honor the manufacturer's warranty, and other conditions may apply. Be clear on this—it's another reason to buy the OWC brand, which meets or exceeds Apple's standards.

Rating: 5/5 Easy to Install and Great Pricing October 30, 2016 This RAM has enabled my old MacBook Pro to handle more programs which has resulted in more work getting done and less crashes/waiting for apps to open.
