Silence Your Mac Boot Startup Sound Altogether [OS X Tips]

By

The iconic Mac startup sound has evolved over the years, but it is a distinctive part of being a Mac user. Sometimes, though, you just want to boot your Mac up silently. You can keep it from sounding out if you hold down the audio mute key on modern Macs (it’s that F10 key on my Macbook Air), but what if you want to disable it completely?

You can drop into the command line to do just that, it turns out. Here’s what to do.

Launch Terminal from the Utilities folder, which is inside your Applications folder. Once it’s up and running, type the following command after the blinking prompt:

sudo nvram SystemAudioVolume=%80

You’ll need to enter your administrative password after you hit Return on your keyboard, since this is a super user command (sudo). When you restart your Mac, you’ll notice that your boot sound is silent.

If you want to return to hearing the Mac startup sound, you can type or paste the following:

sudo nvram -d SystemAudioVolume

Again, you’ll need to enter your admin password to support the sudo command.
