How disable startup sound mountain lion?

The Mac runs tests at boot up and the start up sound is the sign that it has passed the test. If you find a way to turn that sound off, you will not know If there is a problem or not. There is also a certain sound sequence to alert you of a problem with RAM, so the sound has an important function. I've heard of a hack to turn it off, but do not remember what it was.

Hi, check this manual:

Well, it is a hack, so caution is advised; personally, I would not trust anything from anyone who gets paid by advertising for MacKeeper which, according to hundreds of problems posted in these forums, is the worst software one can install on their Mac.

use StartNinja ! worked for me.

it works under Mountain Lion and is even retina-ready:

The 'no software or hack required' solution that works for me:

Turn down your volume all the way before you shut the computer off. Works perfectly on my 2012 MBA.

I try to avoid all unnecessary third-party software.

Using the following link at Mac OS X Hints, you can fully disable your startup sound, without fiddling with volume settings at shutdown.

On my mini, I turned the volume down to where it was nearly inaudible at boot. Turning it completely off had a negative side-effect with two-way audio in Skype, and my external firewire iSight camera.

The startup sound (chime) is the signal to hold down the shift/option/cmd key(s) needed for safe, diagnostic or recovery startups. Remove the chime and you'll find it hard to know when to press, search the forums for people who got stuck that way.

Turn the volume down.

I founded the same soft using Google...

Worked immediately!

Amazing that some "tech" guys "insist" that you need this sound to know that everything is "all right"...

My question to them is: " Does hundred millions of PC's, Iphones, Ipads, Itouch and others devices does have a startup sound to say that's "ok"???

Does your car, your coffee machine, your elevator has a startup sound?

I love, literally love Apple and Steve Jobs, but I still do not get this...

(by the way, I love this app as well: DaisyDisk , let's you know visually what take space on your harddrive)

Actually, the Apple Engineering Team made that decision.

Mac OS runs on Mac computers. It does not run on PC's, iPhones, other iDevices or elevators.

Good luck if you need to use Recovery mode or any other startup key command.

ohhh, really, I learn something here ;-) I am not a beginner. Sorry for you if you cannot think outside the box.

About recovery mode, there is a hundred other solutions to fix this and i will not loose time to explain.

I love Apple and Apple products by the way and if you have not more to add on the discussion, please avoid posting it.

Contact them and ask. Here is the contact info for Apple:

Please do explain at least four or five of the hundred other solutions to recovery mode. A user tip with the solutions would be great. Make sure you test them all first though as required by the ToU.

no problem:

before going deep, some points here:

• I own about 13 Apple Devices since almost 7 years and my country is the first where Apple has the most OS market share:
  http://royal.pingdom.com/2011/03/16/the-10-most-mac-friendly-countries-on-the-pl anet/
  
• Also, I have about 50 "close" friends that have Mac OS products (imacs, MacBook, Air...)

I never, ever had a recovery problems in 7 years and that's why I buy Apple products.I never, ever heard a friend, in my country or in another that was stuck because of the start sound. (i already have had a friend that have to replace it, but starting sound was not necessary on this case).Here 4 situations with a MacBook Air:

1. You try to start the Mac, nothing happen, even if the sound would work. In this case, battery was completly down. So you plug it, wait 3 mn and start it. What would be the use of the sound here? Should they not "spare" some battery just to make the sound work? No I do not think so.
2. You try to start the Mac, you disabled the sound and nothing happen. You bring it to Apple and they discover that your screen is dead. What would be the use of the sound here?
3. You try to start the Mac, you disabled the sound and nothing happen. You bring it to Apple and they discover that your processor is dead. What would be the use of the sound here?
4. You try to start the Mac, you disabled the sound and nothing happen. You bring it to Apple and they discover that you could repaired the problem if the starting sound could be heared. But you just putted on mute before the last shutdown. (so why not make the sound work, even though you putted on mute on this case?)

Seeing your "level" and points, I am pretty sure you will come with many counter arguments and I do not really care about them frankly.

My point is, after 7 years using Apple products, I am more than happy to have them and I will continue to buy them because they are so amazing, it never appear to me that I need this starting sound that causes me more trouble when i start it and my wife or kids are sleeping not too far, trying everytime to put me far away and try to hide the Air under pillows when I start it.

Frankly, if that's going to happen to me in the next 7 years, I would be more than happy to go to my Apple store and bring them back to their specialists and hear I was a bad boy, i should not have disabled the sound. I will not care 1 second trying to fix it myself if I do not see how to fix it. And I will return home, with new Apple products I would have buyed in the meantime.

My turn to ask you a question, if your car tomorrow does not start (you do not hear the starting sound ;-)), are you going to try to remove the motor and see if perhaps you can do something yourself?
If you are a mecanics, maybe, if no, I doubt.

If there so many threads about this and some software build around this, it means there is something about it.

I guess you are going to defend your point telling other things...

If that happen to me, I am sure Apple guys will fix it. That's my ultimate solution. Period.

I'm not sure why you two are going at each other but it seems a bit asinine. The Mac is a Mac because, well, it's a Mac! I imagine the startup sound diagnostic is just another one of many, many things that make a Mac a Mac. Like Swissroro, I've used and owned Macintosh's for years now. Since 1984 in fact. That's why I chose the original Mac pict for my avatar. In that time I've seen a few frowning Mac's come up on the screen of some of the very early Macintosh's and that's it. I've never have heard the startup sound diagnostic on the newer Mac's. I like the idea it's there just in case though. However the grand chime of the startup sound can be a bit obtrusive. I've used the startup pref for years now but it has become obsolete. While searching for an alternative, I've come across several threads that always seem to offer the all or nothing approach. With startup pref, a person could simply turn the sound down. That's all I wanted. All those nifty utility programs, including Cocktail, just gives a person the all or nothing solution. So far the best solution to turn down the startup sound is by using the Terminal (no pun intended) approach. That can be found here:

https://discussions.apple.com/thread/3208783?answerId=21930234022#21930234022&ac_cid=tw123456#21930234

As Cocktail generates unix code to do a lot of what it does, I contacted them and requested that they use the above solution to turn down the startup sound and not to just disable it too.

This is why I hate the forums. Everytime you ask how to turn the sound off some know it all tells you that you need it blah blah blah. No one cares. Just tell us how to turn it the heck off. We don't want it on.

Sorry, everytime I search for a thread there is some guy preaching his Apple tech knowledge and avoids answering the questions. Some of these yahoo's I think know how to do it, but just won't tell you like it's for your own good. I'll deceide that thank you very much. Maybe the best way to do it is let them know, but give them the answer. Honestly if I need beeps to troubleshoot my own computer than maybe I need another job profession other than IT. Of course yes not everyone is tech savvy I know.
