Disable Auto boot on M1 Pro Mac

[bbbc]

It also works on Sonoma 14.7.6 too. I suspect it's because my MBA's firmware was upgraded (to Sequoia) and then I downgraded the OS.

Mutton Jeff, just to say thanks for posting that. I did know there was such a script but had been unable to find a reliable source.
I only wanted the boot at opening the lid in my case for customs checks and accidental opening. The Terminal script for that works like a charm for my M1 on Sequoia.

Well then, I suspect I'm the last one to know but this is now FIXED

Prevent a Mac laptop from turning on when opening its lid or connecting to a power source – Apple Support (UK)

A Mac laptop with Apple silicon will automatically turn on and start up when you open its lid or connect it to a power source. With macOS Sequoia 15 or later, you can change this behaviour without affecting your ability to use your keyboard or trackpad to turn on your Mac.

support.apple.com

Takes you to "Prevent a Mac laptop from turning on when opening its lid or connecting to a power source" Google that if you don't trust the url.

You have be using using macOS Sequoia or later

• Type one of these commands in Terminal, then press Return:
  • To prevent startup when opening the lid or connecting to a power source: sudo nvram BootPreference=%00
  • To prevent startup only when opening the lid: sudo nvram BootPreference=%01
  • To prevent startup only when connecting to a power source: sudo nvram BootPreference=%02

Sorry if everyone knew this but well, I had to tell *someone*

Cheers

Shame the key presses are still there, but one step forward I guess…
