How to Turn Off Startup Chime on macOS 13

This guide explains how to disable the startup chime on compatible Mac computers running macOS 13 Ventura. You will learn how to turn off this boot sound directly through the macOS System Settings interface, as well as an alternative method using the Terminal command line.

Method 1: Disable via System Settings

Click the Apple menu () in the top-left corner of your screen.
Select System Settings.
In the sidebar, scroll down and click Sound.
In the main panel, look for the option labeled Play sound on startup.
Click the toggle switch next to Play sound on startup so it is turned off (grayed out).

Your Mac will now boot silently without playing the startup chime.

Method 2: Disable via Terminal

If you prefer using the command line or need to configure multiple Macs remotely, you can mute the chime via Terminal.

Open Terminal (located in /Applications/Utilities/ or via Spotlight).
Enter the following command and press Return:
```
sudo nvram StartupMuting=%01
```
Type your administrator password when prompted and press Return (no characters will appear on the screen as you type).

To re-enable the sound in the future via Terminal, enter:

sudo nvram StartupMuting=%00
