Ever wanted your MacBook to remain off whenever you lift the lid or connect it to a power source? Apple has released an official support guide explaining how to disable this function.
This method may seem like a workaround for seasoned users, especially since there isn’t a built-in option in Settings. However, it makes sense as advanced users are more likely to seek a way to stop the automatic boot-up process.
Apple’s support document outlines the necessary steps to modify this default setting.
- Ensure that your Mac laptop featuring Apple silicon is running macOS Sequoia or later.
- Launch the Terminal app found in the Utilities folder within your Applications folder.
- Input one of the following commands in Terminal and hit Return:
- To disable startup when opening the lid or connecting to power:
sudo nvram BootPreference=%00 - To disable startup solely when opening the lid:
sudo nvram BootPreference=%01 - To disable startup only when connecting to power:
sudo nvram BootPreference=%02
- To disable startup when opening the lid or connecting to power:
- When prompted, enter your administrator password (note that Terminal will not display the password as it’s entered), then press Return.
If you wish to re-enable automatic startup when opening the lid, you can do so with this command in Terminal:
sudo nvram -d BootPreference
These procedures are helpful for users wanting to adjust the default behavior for various purposes.
It’s important to note that these instructions won’t stop your MacBook from booting up if you press a key or tap the trackpad. For those looking to clean their keyboard without any key input, consider using CleanupBuddy for Mac.
On another note, if you simply want to silence the startup chime on your Mac, you can find a toggle for that in Settings > Sound next to Play sound on startup.
