Hi guys, new to the site, new to mac's, iv'e recently moved from the dark side and purchased a mid 2012 13" macbook pro (non ratina) i5, i want to start by upgrading the ram, now i've looked on apple's website and it says it only supports 8gb of ram, (4x2), but i have watched YT videos of people installing 16gb (8x2), when i run the crucial memory program it says 8gb but if i check manually on crucial it also offers me 16gb.....i'm confused, is there any guru's here that can clear this conundrum up for me....
