James Williams, can you provide a link to the kit you purchased on Amazon. Kit with New battery along with screws, driver and brush. thanks!
I just followed this guide and it really helped me install a replacement cable and a new Samsung 860 EVO 500gb SSD in my aging MacBook Pro 13 A1278 MID 2012. It’s performing like a new machine now! The guide worked fine, but I’m curious why this HD cable costs €45 on Ifixit’s webshop, and only €13 on Amazon.de (I live in Europe)? The Amazon purchase also included two screwdrivers and a spudger.
