How do I turn off startup sound?

thats what i did ...

Worked for me on 2013 rMBP with Mavericks. Thanks.

Turning the mute "on" before shutting down or restarting TOTALLY works perfectly for me too!. No changing any settings, nothing! Too simple and what a bummer that I've put up with this for 6+ years.

I use a small app called Startupsound - which allows you to control the volume or mute ( Works for Mt Lion not sure about Mavericks )

I keep earbuds plugged into the jack. Hit the mute button on the keyboard. (not necessary to hold during startup)

Startup Mavericks.... no startup sound.

Lot simpler than messing around with Terminal or third party software.

(Computer is a Macbook Pro. No idea if this works on all models)

Darksouljp's tip worked for me. Interestingly,MuteCon has not added itself to Login Items (and I have not manually added it),yet it still silences that dreadful Mac noise at every restart. Brilliant!

For anyone interested, here is my step by step to turning off the default startup sound. This builds on Hippomormor's posts back in October, filling in the gaps for basic users such as myself and adding a bit of context. The context may not be perfect, but I'm running Mavericks 10.9.2 and this works.

open terminal

type

sudo vim /Library/Scripts/mute-on.sh

this creates a mute-on.sh script file in a vim (editor) instance

press ‘i’ this will allow you to enter or ‘insert’ text

type

#!/bin/bash

osascript -e 'set Volume with output muted'

the first line means run this script in bash. 'bash' is a shell. A shell is a program that takes your commands from the keyboard and gives them to the operating system to perform.

the second line says “run the following statement 'set Volume with output muted’”.

Applescript adopts a plain English approach and this string mutes the volume. To unmute, which we’ll have to do below, the statement will change to ‘set Volume without output muted’. I guess the plain English approach only goes so far.

press ‘Esc’. This gets you out of the ‘insert text’ mode in the vim editor

hold ‘Shift’ and press the 'z' key twice. This gets you out of the vim editor and back into Terminal

type

sudo nano /Library/Scripts/mute-off.sh

this creates a mute-off.sh file in the nano editor. why use a different editor? not sure.

in your nano instance, type

#!/bin/bash

osascript -e 'set volume without output muted'

- Press ‘control + x’ then ‘y’ then ‘enter/return’

‘control + x’ is the Exit command in the nano editor, ‘y’ for “Yes, please” and ‘enter/return’ to save it to the default chosen file (the one you’ve been editing)

You’re back in Terminal

type

sudo chmod u+x /Library/Scripts/mute-on.sh

press ‘enter’

you’ll be asked to enter your administrator password

then type

sudo chmod u+x /Library/Scripts/mute-off.sh

I was not asked for another password

then type

sudo defaults write com.apple.loginwindow LogoutHook /Library/Scripts/mute-on.sh

press ‘enter’

this tells the computer to run the mute-on script when logging out

then type

sudo defaults write com.apple.loginwindow LoginHook /Library/Scripts/mute-off.sh

press ‘enter’

this tells the computer to run the mute-off script when logging in

Close your Terminal window and restart your computer a couple of times and enjoy the silence.

Hopefully this helps and works for you too.

Actually there is not a perminent solution for turning-off startup chime without third-part apps or writing some commands in terminal.

If you do not want to use 3rd part apps and change some operation system files you have have two options;

1. Press the mute key just before shutting computer down

2. Hold the mute key while turning computer on.

Thanks,

I have checked previous discussions. I think it ought to be user's choice to use it or not.

It's not, if you feel like hacking your Mac to get rid of it Google for solutions, use at your owm risk.

Remember people, Mac just works!

Not if you are foolish enough to hack them,

A lot of steps, but worked! I'm not comfortable with installing apps that do this for you, and was looking for a script instead.

The nano script editor thing got me confused as I was reading your process, but was back on track when the nano editor popped up for me to see after typing the said line code.

I'm running 10.7.5 on a late model 2006 imac.

Thanks for the info!

You had to revive a 2 year old thread just so you could complain?

Thanks for your contribution

Hippomormor, could you help me please? After I have made the changes you mentioned I still have the startup sound but now my computer is totally mute:-) I mean no sound at all. Any suggestion how I set it back? My timeline is off so that is not an option.

Thanks in advance!

The volume of the startup sound is whatever volume you set it to before you turn off your computer.

So just lower your volume to mute before you shut down and when you turn it back on you'll here nothing.

Remember it's the volume of your computer, so pull out whatever's in your audio socket before you lower the volume.
