How to remove the sound when starting a Mac?

If you want to discreetly turn on your Mac in the library, in transport or during a meeting, then this tutorial is for you.

Why does a Mac sound at startup?

A sound emanates from your Mac during its startup, even when headphones are connected to it because the external speaker is the default output of the chime (chime, in French). This melody indicates that your Apple computer has powered up correctly.

The trick then would be to turn down or turn off the volume, by pressing the Mute key (F10), before turning off your Mac. Still, need to think about doing it.

Permanently delete the sound of a Mac at startup

If you tend to forget to turn down the volume, then we suggest you turn it off permanently. To silence the chime for good, you will have to go through the Terminal and follow these 3 steps:

  1. Open the Terminal (Finder → Applications → Utilities → Terminal).
  2. In the Terminal window, type the command, respecting spaces and capital letters: Sudo NVRAM SystemAudioVolume =% 80.
  3. Enter your password and press Enter.

Now, your Mac starts silently until you decide to reactivate it.

If you want to go back and activate the chime again, open the Terminal, enter the command: Sudo NVRAM -d System Audio Volume, press Enter and finally enter your password.

If, on the other hand, you do not want to disable the chime then it is advisable to put your Mac on standby instead of turning it off completely (especially if you plan to use it again soon after).
