MacBook 12" Retina Battery Replacement

Instructional video and guide on how to replace the battery in your 12" Macbook. This applies to the models 2015, 2016 and 2017, and also the 2017's sold in 2018 and 2019. Tools you need: - a replacement battery, obviously :) - a P5 Pentalobe screwdriver - a T5 Torx Screwdriver - a Tri-point Y00 Screwdriver (recommended but I did it without) - alcohol to remove adhesive from old battery
