Do you want your MacBook to stop booting every time you open the lid or plug it in? Apple has published official support documents detailing how to disable the feature.
Without properly switching settings, it’s a bit of a workaround for power users. However, that’s probably fine given that power users are most likely hoping a way to turn off automatic startup.
In the support documentation, Apple provides the steps required to change the default behavior.
- Make sure your Mac laptop with Apple silicon is using Macos Sequoia or later.
- Open the Terminal app in the Utilities folder in the Applications folder.
- Enter one of these commands into the terminal, then press return.
- To prevent startup when opening the lid or connecting to power:
sudo nvram BootPreference=%00 - To prevent startup only when opening the lid:
sudo nvram BootPreference=%01 - To prevent startup only when connecting to power:
sudo nvram BootPreference=%02
- To prevent startup when opening the lid or connecting to power:
- Enter your administrator password when prompted (the device does not display the password when it is entered), then press return.
Additionally, auto-start when opening the lid can be re-enabled on the terminal with this command.
sudo nvram -d BootPreference
These steps are useful for those who want to change the default behavior for a variety of reasons.
Note that these steps do not prevent your MacBook from starting when you press a key or trackpad. For example, if you need a way to clean your keyboard without key input, check out CleanUpBuddy for Mac.
On the other hand, if you just want to prevent your Mac from chiming at startup, there’s that toggle in Settings and play the sound in Startup.
