Issues with replacement SSD
Yes, I already know that the new MacBooks have a new SSD Interface hence why traditional SSD's won't work.
I have an EMC 2978 MacBook with a 820-00875-01 LogicBoard. I tried to use an used SSD of the Internet for this model and it doesn't work. The SSD Model is: 656-0044A.
I am currently typing on this MacBook by booting it over an external drive I had laying around.
