Rating: 5/5 This product did exactly what I was hoping for. January 8, 2016 Needed to boost processing speed on my mid 2007 iMac. Added 6GB RAM on 2 separate cards (4GB+2GB) and noticed better performance immediately. As I've never tried anything like this before on my own, OWC's online installation video was very helpful. Straightforward and very pleased I'm able to keep my old iMac going.

Rating: 5/5 Outstanding! October 5, 2015 Although Apple says that my 2007 MacBook Pro can only handle 4 MB of RAM, OWC said that it could use up to 6 MB, and they were right. My old machine has new life, running the current OS and several new programs that would have bogged it down before.

Rating: 5/5 New Life into an Old Friend August 3, 2015 I added a new hard drive and went from 2 to 6 Gig of ram in my mid 2007 iMac last week. The huge improvement in speed was noticeable instantly. Glad I went for 6 instead of the 4 that Apple says is the max. Wow, what a fantastic difference! I would recommend these upgrades to anyone who feels their old iMac has slowed down. The 'how-to' video for the hard drive made the process absolutely simple. Thanks for a great product and straightforward video.

Rating: 5/5 Pushed an old MacBook to 6GB August 1, 2015 This 6GB kit pushed my bargain MacBook to standards it did not have when it was new. Friends are amazed that I purchased this 2009 MacBook for $100.00 and then upgraded it with a hybrid SDD drive and 6GB of memory. I needed an additional computer with OS 10.5 in order to run some older software. Thanks to OWC, I have what I need.

Rating: 5/5 Excellent Product July 2, 2015 I used these new RAM sticks to replace the 2x2GB sticks that came with my early-2008 MacBook Pro. They gave it an immediate and noticeable boost and the installation videos and instructions are so simple that any person can install these sticks seamlessly. I highly recommend this product.

Rating: 5/5 Exactly what I was expecting June 22, 2015 After my daughter moved from Creative Suite 4 to Creative Cloud, and to Yosemite her older macbook pro the Adobe apps were intolerably slow. According to Apple her machine was maxed out at 4gb of ram. Crutial didn't offer an upgrade. But I found the 6gb upgrade here at OWC. The web site made it very easy to figure out precisely what was available for her system. The order came on time via 2nd day delivery. The instructions for installation were clear (the video very helpful) and I completed the upgrade without trouble.

The result provided a clear improvement when running creative cloud applications. (Not as fast as one might hope, but accdptable.)

This is helping her to preserve the lifetime of this system. She doesn't want to give it up because 17" macbook pros are no longer offered.

I returned the old memory for a credit. My only complaint is that the credit for the old memory is a token amount. (But better than nothing.)

Rating: 5/5 Great customer service! May 27, 2015 I can't say enough good things about the customer service and follow-up. I needed a RAM upgrade and found out from OWC that Apple was wrong in telling me how much I could add. I could, in fact, add more. I got a follow-up call to make sure I was getting what I wanted. Best online purchase experience I've ever had! Now my computer flies!

Rating: 5/5 Perfect solution for Windows crashing problem May 7, 2015 I run Windows under Parallels on an older iMac. After upgrading to Mavericks OS, Windows was hanging, getting corrupted and was generally unusable. I upgraded to 6GB of memory (max possible) from 4GB and it solved the problem. The product was easy to purchase, came right on time, was easy to install and worked like a charm.

Rating: 5/5 mid 2007 iMac memory upgrade May 2, 2015 My 24" mid 2007 iMac had 4GB of RAM & was very slow---upgraded to 6GB (2+4) as OWC advised I could safely exceed the original specs. By following the instructions in the OWC video I did the job in less than 15 minutes. iPhoto and iTunes are now significantly faster. NOTE: I simplified the job by used needle nose pliers to remove the old memory cards.

Response from MacSales.com, Technical Support May 4, 2015 While the use of pliers may have been effective in your case, it is very easy to damage the memory modules and we do not recommend their use when removing memory.

Rating: 5/5 VERY Obviously works, thumbs up! April 6, 2015 I ordered this kit no really convinced to start with....my Imac is tired and wondered if it was worth it. I've got a macbook pro and decided to use the Imac only as a studio with Logic pro. Well once the kit of ram installed the difference was very obvious, faster, everything suddenly worked much much better ( I started to wondering once the rams swapped if there was something wrong with he old ones! that's how obvious the difference was. I must too say that the customer service was incredibly friendly, fast and answered all my questions. Thanks again, I'll be back for more (my Macbook needs ram! ;) )

Rating: 5/5 Late 2007 iMac upgraded to 6 megs of RAM.... March 29, 2015 .....and acting like a youngster again. Great idea to get more life out of a wonderful computer for so little money. Each time I order something from OWC, they come through with service, quality product, and price. And, I got a refund for trading in my old RAM! Did the same with my MBP; now has 8 megs of RAM. Highly recommended.
