Rating: 5/5 Saved my Mac! December 5, 2016 A couple years ago I bought a used Macbook5.2 (mid-2009) as an "extra" machine, the price was so good. But it never performed well, and it became nearly useless after upgrading it from Mavericks to Yosemite as recommended. It would take several minutes to boot, even basic web browsing was painfully slow, and it would often lag several seconds in responding even to mouse movements and keyclicks. Just horrible.

Fast forward to 2016, one of our other machines died. I wanted to "promote" this one to daily use, but its performance was so bad I spent quite a bit of time researching new laptops (including a possible switch back to Windows, with Apple *again* abandoning the moderate range of the market). I'd assumed that this system's 2GB should be enough (and also that 3GB was the maximum, based on my other, slightly older MacBook), but then I learned that (1) Yosemite barely functions on 2GB, and (2) that 6 gigabytes, not 3, is the maximum on this system. So I decided it was worth the risk to spend some money and try to save this Mac.

Well, I've never gotten so much bang for the buck before. Even though this laptop is 7 years old, it functions as well as a NEW machine now. In, fact, it actually browses the web much faster than a Celeron-based budget Windows 10 laptop that we bought recently for another purpose. Boots fast, very responsive in use, handles multiple open apps and tabs with ease. This upgrade was worth every penny, several times over! I should have done this two years ago.

OWC's step-by-step upgrade videos make the job super easy, and honestly it would have been pretty easy even without the video. Just yank the battery, remove 3 screws inside the battery compartment and you have access to the memory bays. Just press a lever to pop out each memory module, press the new ones in, screw the memory/hard drive cover back in and replace the battery. Seriously just a 5 minute job. Part of the reason I'd waited was that I dreaded taking my MacBook apart to do this, but as it turns out you don't open it all the way up. Really, it could hardly be easier.

Rating: 5/5 works great November 30, 2016 Gave the old macbook a boost with SSD and a bit more RAM, saving a thousand bucks instead of buying a new laptop. Happy with the RAM, though I've not noticed much of a difference (probably not making great demands on the 'book).

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.
