Review on 🔧 A-Tech 8GB RAM Upgrade Module for Apple MacBook Pro (Mid 2012), iMac (Late 2012, Early/Late 2013, Late 2014, Mid 2015), Mac Mini (Late 2012) - DDR3 1600MHz PC3-12800 2Rx8 204-Pin SODIMM Memory by Alex Webster

This is the second part I'm buying because the first one didn't work when I combined it with the original RAM, but it works fine when used alone, and also the serial number of the product is not displayed in the memory test, but it is readable and compatible with the Macbook as stated by the seller. The performance of my MacBook was not what I dreamed of, but everything is fine and better than the previous one.
