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.

Reviewer: FloridaMacUser Location: Florida Age: Over 65 Experience Level: Home User Owned Product: less than a month
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.

Rating: 5/5 Old iMac sails on with enough RAM September 4, 2017 This old second-hand iMac had become unusable for a home-based business because its old Safari (because of its old operating system, which also kept other newer browsers from working). Newer Mac OSes required more RAM, so I figured to just go all the way. Mac Sales/OWC's guarantee that this RAM would work calmed my concerns. This entire shipment arrived as quickly as I needed and installed and worked perfectly.

Rating: 5/5 Super simple to install June 15, 2017 The culprit of painfully slow internet was finally diagnosed as lack of memory (computer, not mine). I ordered the upgrade and although I DID need a little help from a friend getting the panel off the Mac to install it, it was an incredibly simple operation which took all of a minute or two. I was immediately back in business and one very happy customer! The upgrade kit was shipped right away via USPS Priority mail and reached me in just two days, the packaging was excellent and, all in all, this was a very good purchase all around. Highly recommend this company and, seriously, any dummy can install this!
