Rating: 5/5 Great product! January 11, 2017 I purchased this 8GB RAM upgrade for our MacBook Pro. Item was easy to find (as long as you have all necessary info from your computer prior to search), the video on the OWC website was excellent and made the installation very easy. I completed the installation in about 5 - 10 minutes, fired up the computer, everything works fine and it is now noticeably faster. Thank you OWC!

Rating: 5/5 Great Products backed by Excellent Support! January 10, 2017 I decided to give my older (but still vibrant) Mid 2009 MacBook Pro some help by getting it's tired, old, butt into better shape. I happened onto MacSales by chance, liked what I saw and ordered a 1 TB SSD and a RAM upgrade from 4gb to 8gb (it's maximum). I'm terrified of opening my computer fearful I will only do more damage and incur greater costs in repairs. I watched the videos on MacSales and they were both straightforward and seemed simple as well. I had no problem installing the new RAM - which gave me the courage to tackle the Hard Drive the week after. Whenever I had a question or hit a snag, MacSales Support personnel were available all the time by chat or phone and all of them were helpful and friendly. The laptop has gotten a much needed kick in the pants and both the new RAM and SSD have performed brilliantly. I'm a more than happy customer and I will be back when I'm ready to perform similar magic on my Mac Pro. Cheers to Macsales, their great products and excellent support!

Rating: 5/5 My mid 2010 MacBook Pro is reborn January 5, 2017 After installing sierra I thought my mbp was dead. After all, it is more than 6 years old. It was painfully slow & apps were quitting left & right. Chrome was unuseable. I took a chance and installed the full complement of ram, an ssd, and a new battery because mine was swollen & the trackpad didn't work. Now I'm in love with my Mac all over again--for well under $400. Installation was super easy & the update was seamless. I now have 500 gig internal & my old drive is external. I could have installed both internal but like having the DVD. Couldn't be happier with my purchase. It boots fast and runs all the apps I can throw at it.

Rating: 4/5 Easy installation, check the number of memory slots on your Mac first January 5, 2017 My late 2009 iMac came with 4GB of memory, and I wanted to upgrade it to 8GB. I thought I would have to replace the old memory with the new because I thought the iMac had only 2 memory slots when in fact it has 4. With the new memory, my iMac has 12 GB of memory, which is more than enough. I could have saved some money if I purchased 4GB instead of 8.

The installation was very easy. There was a lot of lint and dust in the memory compartment, so I would recommend cleaning that with compressed air while you have it open.

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
