Start MacBook quietly - how to turn off the startup sound

Apple has eliminated the startup sound on the newer devices from 2016. However, any owner of an older Mac may be annoyed by the loud startup sound. This is especially annoying when you start your Mac in a library, for example. There are several ways to disable the startup sound.

How to turn off the startup sound of your MacBook

1. Press the F10 key during shutdown. This trick will only work temporarily at the next boot and you will need to press F10 key at every shutdown to keep the startup sound off.
2. You can also get rid of the startup sound using Terminal. To do this, open a terminal by searching for "Terminal" using Spotlight search (Command + Spacebar) and launch it.
3. Once the terminal has opened, type "sudo nvram SystemAudioVolume=%00". You must confirm the command with the administrator password. Finally, enter the command "exit" to save all changes and close the terminal.
4. You can also use a third-party program to make your MacBook start quietly.
5. The program StartNinja provides this function. Laden Sie sich die Software herunter und starten Sie das Programm.
6. Nun klicken Sie auf „Get Current Setting“ und geben Ihr Passwort ein. Danach klicken Sie auf „Off“ und geben erneut Ihr Passwort ein.
