In case you haven’t known, MacBooks with Apple Silicon are built to automatically boot up and play the startup chime (by default) when a user opens the laptop’s lid or when the user plugs the laptop to a power source. Some people may appreciate this enhancement; however, there could be some who find it as an annoyance, especially if they need to do a quick cleanup such as wiping the dust off from the laptop’s screen. But thankfully, Apple now explains via a newly-published support document on how to disable the auto functionality, and you need is the Terminal app. Here are the steps as explained by Apple:
1. Make sure that your Mac laptop with Apple silicon is using macOS Sequoia or later.
2. Open the Terminal app, which is in the Utilities folder of your Applications folder.
3. Type one of these commands in 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
4. Type your administrator password when prompted (Terminal doesn’t show the password as it’s typed), then press Return.
That’s it! Keep in mind that this only works in macOS Sequoia. Also, in case you want to restore defaults all you need to do is to run the following command in Terminal:
sudo nvram -d BootPreference
