Rating: 5/5 Excellent November 28, 2016 I bought the 2 banks of RAM to expand the RAM of my old iMAC from 4 GB to 8 GB. The new ram modules worked just fine when I did the upgrade. I am very satisfied from the purchase. Also, the shipment was smooth and on time.

Rating: 4/5 Works, but problems installing. November 19, 2015 I followed the video to replace the memory, but had problems with the new stick in the bottom slot. Searching found similar sob stories on the Apple Support Communities. I finally got the new sticks working by nudging them slightly, so not sure if the new stick's notch and contacts are out of spec, or the Mini's slots are too loose, or what. Details near the end of the post at https://discussions.apple.com/thread/3693218.

Rating: 5/5 Great memory October 5, 2015 The memory is performing flawlessly in my late 2008 MacBook Pro. The installation went very quickly, good instructions from OWC. I ordered the memory because my laptop was progressively slowing down. It is back to it's old speed now, actually probably faster with most tasks. Strangely when I talked with a rep at OWC about which memory I needed he said oh no, memory won't make it faster. It of course did.

Rating: 5/5 Works great. Install video was a huge help. August 31, 2015 Bought a memory upgrade for a 2009 Mac Mini. The install video made it simple to get into this Mini and exchange the memory. I don't think I would have attempted it without the video.

Thanks OWC.

Rating: 5/5 Excellent August 18, 2015 The memory chips ordered arrived promptly and work great. Most importantly thanks to the video guide they were pretty easy to install - getting into the Mac mini without the video guide would not not have been fun!

Rating: 5/5 New life for my old laptop June 1, 2015 I installed this memory chip in my late 2009 white Macbook, which had become terribly slow and glitchy. Works great now. The installation video was very helpful. The only problem I had was getting those little screws on the back of the computer out and in. I finally got it and am very happy with the result. You need a small metal screwdriver, size 00.

Rating: 5/5 Great memory, running strong over 6 years February 6, 2015 I bought this to upgrade a mac Mini. This mini was used for home automation and then it was used for network backups and now it is used as my HTPC running XBMC. This mac is always running 24/7, never slept in over 6 years.
