SSD of early 2013 MBP Retina upgradable?
I got a early 2013 Retina MBP, 2.8GHz processor, 16G RAM(have the logic board replaced with the same model) and as it known to all, Sandisk SSD(512G) which lead to a annoying fan issue. Tried to replace the SSD with a Samsung 768G one, but it turned out the Mac cannot boot with the bigger size, Samsung SSD. I search the Q&A and found everybody said the SSD is upgradable. So how can my situation happened and anybody knows how to fix it?
