So, I am a happy (genuinely, not sarcastic!) owner of a new MacBook Air (2018). It works great! It’s running macOS 10.14.1 (Mojave).
But it seems to do something that owners of 2016 to 2018 MacBook Pros mention experiencing: That is the second you open up the lid to this thing, the machine boots up without hitting the power button.
sudo nvram AutoBoot=%00
And to unwind this you can run this command or reset the NVRAM completely:
sudo nvram AutoBoot=%03
But when I did this, while the machine—indeed—did not initially boot up when the lid was open, pressing any key on the keyboard—and even the trackpad—will make my 2018 MacBook Air start up. So my question is similar to that other Ask Different post but I am also asking about the issue where the machine will start up if a keyboard key or the trackpad is pressed.
This seems weird to me. Why have a power button when any touch of an input device will start the thing up?
So is there any way to prevent a MacBook Air (2018)—and possibly 2016 to 2018 MacBook Pro—from powering up when the lid is open or an input device (keyboard or trackpad) is touched?
Just let me be able to power it up the good old fashioned way by pressing the power button (with Touch ID) that is in the upper right-hand corner of the keyboard.
