Personally, I am a big fan of all Mac’s startup sounds. And I know that, there are soo many hardcore fans of this sounds. But it can also be annoying, if you’re in a library or a quiet place or the place you do not want to make a noise.
To mute the startup sound; here are some basic tricks.
- If you have to restart your running Mac, press the mute button (F3 on laptops) or lower your volume manually before you restart.
- If you’re starting up your Mac from scratch, press and hold the mute key on the keyboard (F3 on laptops) before pressing your Mac’s power button.
