I was wondering how difficult it would be to add an SSD drive to my MacBook Pro its an Early 2015 model with the following specs. Currently it only has the stock 125 GB storage drive it came with. I cannot install the latest OS update since I do not have enough storage. I have built my own desktop years ago and recently did a motherboard and CPU upgrade on it, but I have no experience opening or messing with a laptop. Any advice would be appreciated. Thank you,
