Customer Reviews
My IMac is blazing fast with the new 8x4 chip card inserts that was easy schmeasy to install. A very expensive Apple upgrade done DIY for only $65.00 in less time it takes to cook a burger. You-guys rock and thank you. Let me know when the late 2014 - 27” IMac can upgrade further with 4x16 chip card inserts. Thank you for my “Ferrari” - iMac.
I would recommend this product to a friend!

My Mac, with its 8GB of stock memory, was really bogging down. The 32GB upgrade was super simple to do and the DRAMs from Mac Sales arrived fast and were a good price.
