How disable startup sound mountain lion?

There's a display thats a pretty good indicator to alert the end user of problems. The sound only alerts my girlfriend that I want to look at **** at 3am.

I used Transplant1's Solution, as Follows:

"The best way I found to silence the GONG is to unplug your external speakers/headphones, and then use system preferences sound. In Sound, just mute the internal speakers and set the sound to zero. After that do a restart; you should not hear the GONG. After restarted, plug in your externals and set the volume to what you want, and then restart. This should solve the problelm."

It works brilliantly on my Mid 2010 2,93GHz Intel i7 Core iMac OS X 10.8.5

Yes, I know the Gong Chime is also a diagnostic Tool.

If I run into problems with my iMac I know how to fix it and without recourse to this idiotic intrusive noise.

This is ridicoulus! Where is the logic?

The "solutions" seem to be:

1. Turn down the volume before you shut the computer down

2. use external speakers and turn down internal speaker volume

3. use a third party software

4. it's a mac, learn to like it

No real solution, only cumbersome procedures and uncertainties regarding if the procedure was performed before the computer was shut down (my wife and kids love to play music at very loud volume and if they turned the computer off, I am waking up the entire family when I start it up at night)

And, the logic is way off concerning the necessity of the chime. Either it is a vital function, or not. If it is vital (as many seem to claim) one should not be able to silence it by just turning the volume down before turning off the computer! If it is not vital, to me pretty evident as it can be bypassed, it should be easy to switch off completely.

I am totally behind this one:

It's exactly it! ;-) R

Well, to get to the recovery and other boot options, you can simply press and hold the key combination you need while turning on the computer, as far as I know. No need to wait for any sound or anything like that. 😉

Also, the Mac OS startup sound cannot be used for diagnostics just because one can't remember for sure if he or she muted the system volume or not before the most recent shutdown, so he or she can't be 100% sure if any sound must be played back. 🙂

Being annoyed so much by that ringing C major piano chord personally I vote for an official system setting, i.e. for something like this:

[x] Enable system startup sound

Cheers, guys. 😎

yep! +1 ;-)

Totally onboard, with the "hack." A bit annoying that the "experts" in the forum won't just say something like, "yeah, dude, it is TOTALLY annoying and there's not really a good reason for the startup sound - but there's no approved Apple solution." It's "the signal to hold down the key combination for a safe startup"? Really?? Do you mean I'm the only Apple user who doesn't have their fingers poised over the shift/option/command keys every morning at 5 AM anxiously anticipating NOT hearing the startup sound?? C'mon, guys, I think I'll know if my computer turns into a desktop ornament whether or not I'm alerted by the obnoxious "BOOOOONNNNNNNGGGG" that wakes up my kids.

StartNinja it is. 🙂

Boooooooooooooing! Right back at ya! It so loud my roomate down the hall hears it with his fan on and his door shut.

StartNinja didn't work for me. I think I have the late 2012 or early 2013 model. Seems like nothing works for it.

Then stop turning it off, closing the lid works just fine, no noise, no waiting for it to boot, better for the Mac as well.

Unless of course you prefer to wait, it's up to you.

It's an iMac. Who are you referring to?

Then just walk away and let it take care of itself

Step 1 - Turn Computer Off

Step 2 - Come back to desk, turn computer on

Step 3 - BOOOOOOOOOOOOIIIING!

I just get up and walk away, the machine sleeps, When I return I touch the keyboard and it instantly wakes up, no boing.

But as you prefer to keep turning it on and off you waste time, increase wear and tear on the machine, and hear a boing.

I prefer my method

Ok, I don't know why, maybe because I been up all night, but when that last dude posted the boing thing I haven't stopped laughing. Anyway...

Look, I boot into Windows (bootcamp) to game. I'm one of the few that probably games on their Mac. So normally yes I do keep it booted up and don't hear it.

I can't cover the speakers, because I can't see them, and the blue tooth keyboard mute thing doesn't work because it's not hardwired I guess?

The keyboard mute works for me (iMac 2011, MBP 2009 and 2011) you should fix that issue.
