Summary

  • In 2016, Apple started to include an auto power-on feature in its MacBooks that turned on the laptop when the lid was opened or when USB-C power was plugged in with the lid open.
  • Some users, however, found this feature annoying, especially when trying to clean the screen or when undertaking activities where they did not want the MacBook turning on automatically.
  • In January 2025, Apple added an official way to turn this feature off for M1 and newer MacBooks.
  • For Intel MacBooks, there was already a Terminal command to turn it off, but this command did not work for M1 MacBooks.
  • To turn off the auto power-on feature, users must enter a command in the Terminal, after which they should fully shut down the MacBook and then test it by opening the lid to see if the setting has taken effect.
  • To reverse the setting, users should enter a different command in the Terminal.
