I have a MacBook Pro Mid-2012 15inch, stock 8GB RAM. I was worried when it arrived because the package only says: "Compatible with: MacBook/MacBook Pro Mid-2010, Early-2011, Late-2011 and iMac Mid-2010, Mid-2011." Missing MacBook/MacBook Pro Mid-2012 as it says in product description online here. However it works fine, I installed the two chips and it started up no problem, and under "About This Mac: Memory" it now has "16GB Installed" My Mac now runs noticeable quicker loading and running multiple apps. I also installed a Samsung SSD a couple years ago. For a 7-year old notebook, this thing runs fast and like new. It was definitely worth the $2,000 investment 7 years ago. There is no way a PC laptop would still be running 7 years later as good as this.
