Rating: 5/5 Works great in my 2008 imac March 25, 2018 This memory upgrade was a good match with the SSD I had previously installed. I was impressed with the service from OWC over shipping delay to Canada, which turned out not to be a problem in the end. Have been using the memory card for several weeks now without any issues , very stable. Most noticeable when having multiple tabs open in browser. Previously the computer would bog down or get close to it. Now there memory to spare and more speed. Also boots faster, loads apps faster.

Rating: 5/5 OWC to the rescue! September 13, 2017 I don't think I've ever had a bad experience with OWC. My mother's old iMac had become slow as sh...ugar. It had a total of 1GB of memory. After swapping out (a super easy 3 minute procedure) the two 512MB (1GB total) memory sticks for two 2GB (4GB total) sticks, the computer is now running smooth and fast. I went with 4GB instead of 8GB because the performance increase would have been negligible, especially when compared to the price difference. How do I know this? Because OWC has benchmark performance results for all different memory upgrades for all Mac models on their site. Kudos, OWC.

Rating: 5/5 Excellent August 22, 2017 I always order memory for my computers both at home and at work. I have ordered in the past from other large companies and even though the price may be nearly as good as at MacSales, the items don't come with the fabulous warranty that you get from MacSales. Just because this vendor caters to Mac does not mean that the memory won't work in, PC.

Rating: 5/5 Memory for Macs May 8, 2017 I have purchased memory for many, many Macs over the years. MacSales are the ones I love to work with because their documentation and customer service is exceptional. I was a tech for years, but software. Their document instructions are so simple anyone can change out memory and hard drives. Thank you for being there for us laymen who have stepped out of their box and learned to put in memory, etc. I have NEVER had a problem with memory, except one time (many years ago) the computer kept locking up after installing. They shipped me memory right away to replace the faulty. Thank you!

Rating: 5/5 Rock Solid Performance January 28, 2017 I purchased this memory for an older mac years ago and it has increased system performance since the day I installed it. Easy to install - my mac is old enough to still have an access panel for the memory :) Has not given us any trouble over the years and will probably be working great when we no longer have use for the old mac. But for today, and the foreseeable future - all systems GO.

Rating: 5/5 A smart choice January 10, 2017 I would say a great investment to breathe new life into an old iMac. I have had this iMac since its release, and since then have used it less and less. Since my newer MacBook has died, I have made the return to working on my old 2008 iMac. Of course it's pricey, but I wish I have made this upgrade sooner. The start time has doubled, and my iMac is maxed out. Now the next step is an ssd. Recommend this upgrade for anyone, who thinks their iMac has no future.
