Disable Mac Startup Sound permanently

In between starting your computer and signing in, you hear the typical Mac startup sound. It indicates your computer has passed the startup diagnostic test and all the hardware in it is working properly. But, just like me, if you prefer to boot up your Mac in silence the better option would be to disable the sound chime.

Depending on the version of macOS you're running, you might hear a startup sound shortly after pressing the power button to turn on your Mac. As desired, you can enable or disable the Mac Startup Sound.

On your Macbook, go to the Apple menu (visible in the upper-left corner of your computer screen).

From the list of options displayed, select System Preferences.
