Introduction
The Auto Boot feature powers on your laptop as soon as you open the lid, so it should be disabled before undertaking certain repairs. Auto Boot can be found on 2016 (and newer) MacBook Pros and 2017 (and newer) 12" Retina MacBooks.
This guide will walk you through the process of disabling Auto Boot, and then re-enabling it when your repair is complete.
Note: Disabling Auto Boot may not work on Apple’s newer ARM-based M series MacBooks released in late 2020 and later. At this time, we don’t know any procedure for disabling Auto Boot on devices equipped with Big Sur v11.1 or later.

hello may i ask, how do u make it Jeff$? mine’s scarlet$ and i want to change it but idk how
You change the your user/Homefolder name
You do not need to change it for the command to work. But if you really do want to for a different reason, rename your home folder name.
I can’t type anything into the terminal…what am I doing wrong?
