OWC Memory 8GB (2X 4GB) DDR3 PC3-8500 1066MHz SO-DIMM RAM | 240-Pin Compatible with MacBook and MacBook Pro Unibody (Late 2008 - Early 2010), Mac mini (2009-2010), iMac (2009)

Works as expected.

Good memory for the price easy to install.

I was nervous because this is my first time buying and installing memory on a iMac computer. I have a 2009 late iMac which comes with only 4gb of ram. I mostly use the computer for video editing in final cut pro, I use Lightroom, and adobe Photoshop. I was all was having crashes and my computer would freeze up while doing these programs. When editing my videos would be so darn sluggish in final cut pro to wear I wanted to just hang myself with a thread of yarn. The shipping was fast and the memory look so good in hand. I exchanged it with no problem. The computer booted up as normal but a tad bit faster. Once it came to the main screen it didn't take forever for programs to pull up which was amazing. I opened up Final Cut Pro and It's was quick. Not lighten fast but it was quick. I started editing some footage and mannnnnn!!! That joint was working way faster than before. My videos weren't skipping like before and my playbacks and imports were smooth. I've seen a big difference in my speed performance. If you need a boost..this memory will restore the walking dead. I do still have issues every now and then which isn't all the ram but the ram is solid and you should get it now if you need that boost.

Booted right up. Has some unusual behavior though. When this Mac Mini (2010) had only 2 gigs of ram the video on YouTube ran real slow. Now it is much faster and runs video much better and without hesitation. However, while running programs, the system does periodic time outs that last nearly a second. I don't if the memory has anything to do with it though. I was given this Mac to learn a specific program native to Mac. I am a lifetime Microsoft PC user. I was thinking of upgrading the HDD with an SSD. Other Mac Mini users have done this and it seemed to reportedly work out well for them. I have SSD on 2 different i7 PC notebooks and they are extremely fast. I'm thinking its a timing issue between the new ram and the dual-core cpu. Even though this ram is the same speed as the old ram, it may be too much for the cpu? If anyone has any takes on this to share, please do.Update and review change 1/19/2018I called OWC tech support today about the new memory I purchased from Amazon. When I called OWC wanted to establish where I got the memory. I found out it was from another vendor at Amazon. However, they were still very helpful and started a ticket. The tech, Chris T. was very helpful and gave me some recommendations to try out. My computer started behaving better afterward but still glitched out on me. This time it was for a much longer time 5-10 seconds. I then moved the Mac Mini in question and it glitched again. During the conversation with Chris he said it may be a video issue, in passing. Remembering that I grabbed the HDMI cable and got the Mac to glitch out on demand. It is a video issue. I wanted to give kudo's to Chris and OWC for the great tech support.

My MacBook unibody is my go to laptop it has all my files and it had been running really slow. I decided to try and give it some new life before replacing it. It's a late 2009 so I ordered a New battery, new fan, SSD, and more Ram. Apple said the most I could go was 4GB but I had read some where (OWC) I could go as much as 8GB. I was really undecided, ignore Apple and take a chance and just go big. I'm so glad I went big. As soon as I received my new RAM I installed it. It was the first item to arrive out of my order and I wanted to see if that change alone would make a difference. It made a huge difference. My laptop is like new. I can jump from page to page no waiting, no spinning dial, truly amazing. Now I'm thinking I really don't need to change out my Hard drive to Solid State, hard to imagine it running any better.

Economical and convenient acquisition of RAM upgrade for an older iMac.Installation was a snap.This is primarily for enhancing function of Logic Pro 9 digital audio workstation software -- I've checked it out with the Activity Monitor app and it appears the program is making use of additional real memory, as desired.

I made a mistake and went to Fry's because I did not want to wait for an order to be shipped. I wasted my time and money, the Fry's memory was not compatible (I have since learned that iMac's are fussy). I installed the Fry's memory and the iMac screamed at start up, I never want to hear that sound again. So, I ended up doing what I should have from the onset - ordered OWC memory. It was compatible and easy to install - OWC also has great videos to help you use their products and that only adds to the value of this brand.

Did some survey and find this brand, price is higher a bit but given it’s reputable and mostly comments are positive so give it a try.I am amazed at the first glance by its simplicity and brand new appearance. It’s not only compact with old Mac book but also old gen intel chipset notebook, it’s an excellent upgrade.All in all I am satisfied with this purchase experience.

Ships on time. Great product that works! Highly recommended
