# Just how do I disable or remove the startup appear my Mac makes?

Everytime I activate my Macbook Pro it proceeds up sound. This is aggravating given that there is no quantity or capacity to transform it off. I simply do not desire the audio to dip into all.

Just how do I disable this startup audio?

Open Terminal.app and also type :

sudo - s

Give the password when requested for after that :

cat >/private/etc/rc.shutdown.local
#! /bin/sh /usr/bin/osascript -e 'set volume with output muted'


after that press Ctrl - D and also type "exit". Next time you'll reboot in silence BUT you'll need to by hand reset the sound quantity (F10, slider ...) if you intend to listen to some songs once more. In theory it needs to be feasible to run under/ private/etc/rc. neighborhood a manuscript to do it (' set quantity without result silenced') yet that appears to act unevenly.

I have not seen that audio on my MacBook Pro for ages, and also today I identified why. The MBP appears to bear in mind 2 collections of quantity setups ; both for having - no - earphones - connected - in, and also for having - earphones - connected - in.

I generally have my exterior audio speakers connected in - when I'm at residence, and also when I'm travelling/way from residence clearly I do not. At some time in the past I have actually transformed the quantity to absolutely no when earphones weren't attached, and also currently when I start the MBP up there's no audio.

You can attempt this (though it's not specifically sensible) - turn the quantity on your Mac right to absolutely no, after that reactivate the computer system. I believe you will not listen to the startup - audio. Like I claim, not actually sensible yet if the start - up sound frustrates you sufficient, you could simply get involved in the behavior of transforming the quantity down prior to turning off. : -)

EDIT : Just knew this this factor concerning transforming the quantity down has actually currently been made in various other solutions below, so do not hesitate to overlook this!

You can make use of StartSound.PrefPane which primarily simply establishes the quantity to 0 when you closure and afterwards transforms it back up after login.
