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.

Reviewer: Teke

Rating: 5/5 Exceptional Service February 5, 2018 New memory cards were shipped promptly. However, it appears that USPS lost the package.

I opened up a chat on a Sunday. The MacSales representative was very helpful in taking my information, but (as I expected) there was no one that could help with tracking the shipment on the weekend. However, a MacSales representative contacted me on Monday, as promised.

After exchanging information about the USPS tracking system feedback, MacSales promptly shipped replacement memory cards. This time, by UPS.

Great service and communication all the way around. By the way, the memory cards are exactly as ordered and are working great.

Rating: 5/5 6GBUpgrade November 28, 2017 I used the 6 Gb upgrade kit to speed up my old 07 I-Mac which only had 2 Gb of original memory in it. The memory arrived quickly, and was packaged securely. Removing the old memory and replacing it with the new was easy and quick, it only took a couple of minutes. When I started up the computer, it recognized the new memory right away. The start up time and computer response are now a lot faster, about 1/3 the time it use to take. I sent the old memory back in the protective packaging to Mac Sales.
