StartNinja starts up your Mac with silence and stealth.

Macs don't have a built-in way to mute or silence the system start-up chime. If you're in a library or coffee shop you don't always want that start up chime to play. Now you can silence the Mac OS X Lion start up chime with StartNinja. It is a free and simple desktop utility that silences the start-up chime and will resume previous sound level after logging in.

Note 1: Does not work with iMacs

Note 2: The system start up chime is played through the internal speaker. If speakers or headphones are plugged in the more...

Hi all,

Just my input for getting this to work on an imac, running mavericks (i'm by no means a tech-person so this might only work by chance, and only work for me but thought i'd share anyway!)

Download StartNinja and install as normal, once installed, go into applications and pin StartNinja to dock. option click to open at login. this should cause the startup sound to be muted next time you power on (i think you can close after it's opened at login, for it still to work but haven't tested this yet.)

Let me know how it goes! :)

Just installed this on my late 2013 iMac with Mavericks 10.9.1 installed – no more startup chime.

There is a slight crackle at startup, but nothing that would upset anyone in your favourite coffee shop. Make mine a double-shot mocha.

For those looking to replace either the venerable StartupSound.prefpane or Psst, both which allowed you to lower the volume to your desired level (rather than only mute it), take heart: you can modify StartNinja's shell scripts to do just that!

Go to StartNinja > Contents > Resources, and load muteOn.sh in a text editor. Change the language in the quote marks to read "set volume output volume [number between 0-100]." You can change the login volume as well by modifying muteOff.sh in the same way.

You can verify the path to the login/logout hooks by typing these two commands in Terminal:

sudo defaults read com.apple.loginwindow LoginHook
sudo defaults read com.apple.loginwindow LogoutHook

@Acuraice: If you give it a moment's thought, you'll realize that the chime sounds BEFORE the boot process has even begun, so there's no way it could possibly live in a file that can't be accessed until after the process has completed.

this program is useless if it cant work on imacs!! why regardless of what the developer says,with a simple system hack anyone can edit or even remove the startup chime from ANY MAC!!!

Go to system/Library/Components/CoreAudio.Component/Contents/Resources and do a show packages contents on it by holding "control" and clicking with the mouse,select show package contents. then simply browse to the system sounds you would like to edit or remove including the system startup sound. Done. and FREE!

The startup sound does NOT live at the location you've specified, and, as a matter of fact, I'm not aware of anybody ever having located where in OS X it lives; the consensus is that it's somewhere in firmware, and that although it can be silenced it cannot be touched.

@AcuraIce, sorry StartNinja does not work for you in your situation. If I could figure out how to silence for iMacs I would be on it immediately.

@artie505, thanks for the back up! :-) I know the app looks pretty simple, however, dealing elevated privileges is not simple.

the startup system sound does in fact reside there,just replace it with a blank mp3 and rename it the exact same name startup sound and it will play the blank mp3 upon each restart, to restore,just replace back in the same location with the original system sound. done and again FREE!! rookies!

How about instead of thinking you're so clever and cute you identify, by its EXACT path, the SPECIFIC file that you think is the startup chime.

I've followed the incomplete path you've provided more than once in OS X 10.6.8, and the startup chime is not present where you've said it is.

I stand by my earlier comment: To the best of my knowledge, the OS X startup chime is not only untouchable, it's never ever been located.

Yo, Acuraice: An anxious world awaits your pearls of wisdom.

hey A hole you are so friggin wrong its not even funny!! first of all the sound does reside if you use my directions precisely and show package contents in the resources folder of the core audio components. and second of all i have successfully disabled the startup chime for years now on both of my intel macs running mountain lion with cocktail . so go f yourself biotch!!!!

You've quite obviously never looked in /System/Library/Components/CoreAudio.component/Contents/Resources/SystemSounds or you'd KNOW that the startup chime is NOT in there; what's your point in making up stories?

(Cocktail? Why do you need a $19 app? You can do it yourself…and FREE! [Refer to your own posts for incorrect, and useless under any circumstances, instructions.] And what does Cocktail have to do with anything, anyhow?)

Does exactly what it says on the tin. No more 'tadahhh' when i boot up. I had considered taking my Mac Pro apart to disconnect the annoying tinny speaker, Start Ninja is a much easier solution.
Not a complaint and maybe can't be done but its a pity its not a preference pane. Would be easier to alter if i ever needed to rather than trying to remember the name of a programme.

I may be mistaken here, but doesn't the start up chime also signify that the start up test has competed successfully? Maybe this has changed, but, from past experience when I didn't hear the chime and checked the system profiler that RAM had not passed the test.
