I've got a 15-inch mid-2012 non-Retina MacBook Pro. Apple's website explicitly states that the maximum RAM supported on this machine is 8GB, but I see that Crucial is selling an upgrade to 16GB for my machine. http://www.crucial.com/systemscanner/viewscanbyid.aspx?id=A978FEAC31D926C3 (I found this link by using the Crucial System Scanner, and also verified the stated compatibility with my machine by using Crucial's compatibility chart.) I telephoned AppleCare and spoke to a senior person, who reported back that the reason that Apple's website lists the 8GB maximum for my machine is that the motherboard won't "see" anything past 8GB of RAM. He said I could install the 16GB of RAM but that it wouldn't do any good. Since Crucial is actually selling 16GB of RAM for my machine, either Apple or Crucial is misinformed. Can someone please comment whether you have ever upgraded from 8GB to 16GB of RAM on this model of MBP, and if it made a difference? Metrics would help if you have them! Thank you.
