I am in the market for a new MacBook Pro 15" to replace my 2009. I mainly use this for basic internet, MS Office and when I travel to be able to play movies from it to hotel TV through HDMI (which my 2009 does not carry sound through HDMI). I have seen a lot of decent deals for 2012 MacBook Pro's with decent processors but I am hesitant due to it being a 2012. I would like to be able to run Sierra and is a 2012 able to have the ram upgraded? Any insight?
