Introduzione
Prerequisite-only guide for disabling Auto Boot, and then re-enabling it when your repair is complete. This is an abbreviated version of the guide How to Disable Auto Boot.
The Auto Boot feature powers on your laptop as soon as you open the lid, so it must be disabled before undertaking certain repairs. Auto Boot can be found on 2016 (and newer) MacBook Pros and 2017 (and newer) 12" Retina MacBooks.
