Rating: 5/5 Memory Upgrade is a Snap November 26, 2015 The OWC website makes it easy to figure out exactly how many slots your Mac has and offers numerous appropriate upgrade options. Memory chips are shipped quickly. Instructional videos make the actual install easy, even for a novice. Chips removed get sent back to OWC and your rebate is mailed. It has been a pleasure dealing with OWC on the memory upgrade for my Mac.

Installed 6.0GB Memory Upgrade Kit from OWC and El Capitan. Everything now seems to be as fast as you can expect on a MAC this age.I think this extended the life of my iMac by at least two years. This is memory kit is high quality and easy to install.

Rating: 5/5 adding 6GB memory to 2008 iMac from OWC August 16, 2015 OWC is a company who's stringent standards are as tight as the Apple 2008 iMac , that was running with the original 1+1 gigabit memory factory installed and that I was using as my computer kept becoming more and more sluggish. After a quick and easy to find, best company making memory especially designed for Apple products, I read inmortant information that I could indeed treble my Memory power by adding from OWC a 2+4 GB, two chip memory set that I easily in under 5 minutes installed and which OWC sent speedily to my home and in great packaging and there is even a buyback program that I can easily send back to OWC in their original shipping packaging and recoup a small amount back on my original purchase. I highly recommend using OWC for many of your needs.

Rating: 5/5 A New Lease on Life for my Older iMac May 25, 2015 My 2008 iMac was beginning to feel a little sluggish; however, the hard drive was only about 30% full. After a little research, I decided that increasing its memory from 2 GB to 6 GB would be a worthwhile upgrade. It was, and it made a significant improvement in operating speed. The installation was a snap--even for a non techie like me. The price seemed fair, and the kit arrived when promised.

Rating: 5/5 Easy to Install Works Correctly May 25, 2015 The memory cards were easy to install with concise instructions. The additional memory helped speed-up my 2008 Mac after installing the Yosemite operating system. Yosemite, because it is a memory hog made my Mac almost useless. Good prompt delivery too. No problems with the new cards. Thanks OWC john

Rating: 5/5 pleased with my transaction April 25, 2015 Apple says the iMac I purchased RAM for would only accommodate 4 GB. Another major RAM company says the same thing. OWC, on the other hand, tested 6 GB of RAM on iMacs, found it worked, AND guaranteed that it will - so it was a "no risk" thing for me to order from them. I also appreciated being able to get a rebate on the RAM I removed from the iMac. The RAM arrived quickly and the iMac had no problems with it. And my rebate for the old RAM was processed quickly as well.

Rating: 5/5 6 gigs of ram in my 2008 iMac April 5, 2015 With this 6 gig set, my 2008 iMac is now happily running 6 gigs of ram. I've read that some folks see only five gigs when installing one 4 gig module and one 2 gig module but my machine is seeing (and using) all 6 gigs with this OWC ram.

Rating: 5/5 Fantastic March 19, 2015 I like OWC. These guys test each and every product they sell pretty thoroughly. They make sure that the RAMs they are selling for a particular version of mac is indeed compatible. I have used their product thrice and every time I have had the best experience. My mac had become pathetically slow and needed a RAM upgrade. Apple's site did not do a good job in telling which particular type of RAM should I buy. OWC, however, had all the necessary details (including how-to video). My machine is working much much faster now and I am enjoying the product very much.

Rating: 5/5 Worth EVERY penny - TOP NOTCH ram! March 5, 2015 After much research and the temptation to save a few bucks, I decided to go with OWC. First, the customer service was perfect and the shipping...ULTRA fast! Receiving the 6gb ddr2 ram for my iMac 8,1, I gleefully installed the ram expecting a great performance boost. I was not prepared for the speed that my old 2008 machine roared back to life with! The performance is such that I darn near cried with joy! Thank you OWC for an amazing American Made product, and you have gained yet another faithful customer!

Namaste'

Rating: 5/5 No sweat January 15, 2015 My experience with OWC can be summed up in two words, No Sweat. First I checked the website for availability of the additional memory that I thought my computer needed and found out that not only did they have it but that I could add more than I thought because OWC had the Apple stats that applied to my iMac. I bought the memory at at a most reasonable price, free shipping and OWC included very helpful instructions for putting the chips in myself. Done. In 3 days I had my iMac going from slow to insane! Love it!

Rating: 5/5 It's like having a new computer again. November 23, 2014 My old macbook from 2009 was getting pretty slow. I was worried that I would need to buy a new one. Then I discovered how easy it was to upgrade the ram, and started researching how much ram I could add. The official word from Apple was 4 gigabytes, but OWC said differently. Taking my Mac from 2 gigs to 6 gigs made it run like a new computer again. This is easily the best investment I've made in my computer since the initial purchase.
