Rating: 5/5 Freakin' Fantastic! June 17, 2016 Apple said we can only have 4Gb of RAM, but MacSales.com said no way! Here's 6Gb ready to install ... and IT WORKS!

Don't stress, their combined package of 4Gb and 2Gb of RAM just clicks in and works, so we're very happy. It's given an old laptop new life.

Rating: 5/5 New life for my mid-2009 13-inch MacBook May 5, 2016 My little 2009 macbook wasn't being much of a help anymore, and after the upgrade to El Capitan, it was pretty bad. Painfully bad, enough to think of getting rid of it. I decided to max out the RAM, and as I could only go to 6 GB, I did. The price was great, ease of installation a no-brainer.

Now, I coupled the RAM upgrade with a new 1 TB SSD, so I can't claim that all the speed increase is due to the memory improvement, but it would most likely still be limping in some respect without it. As it is, now it is FAST and and I am in love with my little macbook, and it does everything SO WELL and SO FAST!

Definitely recommend the memory upgrades from OWC.

Rating: 5/5 Worked great for me April 18, 2016 I had a 2008 iMac with 2Gb of memory that had slowed to an unbearable snail's pace. I only use it as a server for my movies etc because the Photos app just couldn't cope with the load of my 11,000 or so photos. So I was just about to upgrade to a new iMac when I thought I'd give this a go.

I upgraded to 6Gb of memory and did a clean install of Yosemite, and now my old clunker of an iMac has a new lease of life. It's not instantaneous by any stretch, but whereas before I'd have to wait 10-15 seconds for iTunes to open, and 15-30 seconds of 'beachball' when I scrolled through a page of photos, now my wait times are down to a couple of seconds. So for me it's a usable machine again.

Best $100 upgrade I've ever done.

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.

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 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.
