I want to upgrade to 32gig can I do that and what do you recommend I use and where should I get it?
Everymac says no.
The RAM is soldered to the motherboard &amp; cannot be changed.

16 GB of RAM is onboard and cannot be upgraded to a higher capacity at the initial time of system purchase or later.
