Rating: 4/5 Not compatible with MacBook 3.1 July 23, 2020 This memory kit not compatible with MacBook 3.1. Assume these modules have another CAS Latency (CL4), which is not compatible with CL5 of original RAM modules. Had to return it for refund. Instead bought another 4Gb RAM kit (OWC Item #: OWC5300DDR2S4GP), which upgrade was successfull with.

Rating: 5/5 Allowed expansion of my old iMACs RAM July 3, 2020 Allowed me to expand the RAM on my old iMAS to 6gig of RAM (more than the specs say). This helped keep it going for a few more years. But after 12 years it is time to upgrade so I just got a new iMAC. I will be purchasing additional RAM for this new purchase from macsales, the best place to get your tech-on.

Rating: 4/5 Might not work, but.. May 23, 2020 I ordered the 6GB upgrade kit for my old Mac pro 15 inch early 2008 to put some pep into it. It's max ram is 4GB. The first kit I ordered did not work giving me all sorts of beeps and crashes. After reaching out the OWC techs it appeared that probably one or both of the sticks were bad so I returned the kit and after a back order delay the new kit arrived, I installed it carefully making sure it was snug in its socket and fired up my laptop. To my great disappointment my laptop didn't even startup at all!! Tried it 3 more times and zilch!! At this point I was mad! As a super last resort (rolling the dice) I tried swapping the kit's 2GB stick (4+2) with my original stick as a " might as well try anything" AND low and behold my laptop fired up quickly and sped through the boot up faster then before. I went through the apps and internet to see if it would crash but it held up beautifully. Left it on all day, shut it down,reboot with no issues. It's working great and has boost my laptops performance. My experince with this kit might be unusual compared to others but OWC has a stellar reputation for it's products so it might have been a curious combo of my laptop's "wiring" or incompatible sticks or none of the above. Who knows! It Works!!

Rating: 5/5 So far unbelievable May 7, 2019 I waited a month here in Canada to get this....Why? Because for a hundred bucks my 12 year old macbook makes a Chromebook look like garbage. That's why.....Fantastic service. Many thanks to you all. I've been experimenting with Windows 10 on this macbook, and all of a sudden the extra Ram has made it into a new computer. Outstanding. And I thank you all for bringing life to older computer's that normally would be junked. No need.....great tracking and fast out of the bin...YOU GUYS ARE AWSOME! From one old original from the beginning computer user.....Thank you.

Rating: 5/5 GREAT FOR AN OLDER MAC BOOK June 18, 2018 I have an old, 2006, Mac Book that I keep around as a spare. A few weeks ago, when attempting to boot it up, it began emoting the dreaded "honking" sound. This indicates a potential problem with RAM. I re-seated the RAM... then attempted to start it up with one stick... then the other. After swapping, the RAM, the honk continued.

Thus, I purchased this product. I plugged both sticks into the computer and was greatly relieved when the familiar Mac chime sounded upon start-up.
