Q: disable start up sound

On Leopard I could simply put down the volume before a shut down, and I had no anoying start up sound.However this seems not to work anymore on Lion.Which possibilities do I have to start my system without the roaring bong?

    It is outrageous that so many people keep on complaining about the near impossibility to mute the startup chime. The user must be able to perfectly predict the future and mute the sound before shutdown if they foresee that the computer will be booted in an environment where silence is desired.

     

    Until around 2006, it sufficed to plug in headphones to prevent the chime from being played through internal speakers. Then Apple disabled this on new Mac models. They only left the workaround of muting the sound before shutting down. Judging from this thread, even that workaround is under threat.

     

    Years ago I filed a bug report about the impossibility to mute the chime. Apple engineers closed the bug as “behaves correctly”. In other words, someone has really decided that the chime must sound unless the user was visionary enough to take precautions. Common sense would allow the user to mute the chime on-the-fly by holding down the ‘mute’ key while booting. Apparently this has worked on some models, but it does not on my MacBook Pro and therefore I just woke up everyone in the house again due to my lack of clairvoyance.

    Don't know if this helps or not with Lion but in the Mountain Lion version of Onyx I discovered only this evening that under the parameters tab and then the log in tab there is an option to turn on and off the startup sound.  It has been working so far.  It would be better though if it showed the option you selected but Onyx if free and it works.

    Why someone would install an entire application or preference pane to disable a sound, I have no idea.. You do realize your just letting all those little useless programs eat away at your system resources...

     

    You can disable the Mac startup sound with a single command line... Just open terminal and copy and paste the folowing line.  Press enter.  You'll be prompted for your admin password because your attempting to run a system command.  Satisfy the prompt.  Restart in silence. 

     

    sudo nvram SystemAudioVolume=%80

    because it simply doesn`t work! That`s why. And why would setting the volume to 80 percent be silent anyway?

    I cananot believe this thread is still going and people are still complaining.

    The solution is simple:

     

    Chime OFF

    sudo nvram SystemAudioVolume=%00

     

    Chime ON

    sudo nvram -d SystemAudioVolume

     

    Chime % of ON

    sudo nvram SystemAudioVolume=%10

    ----

    Here is what you see in terminal:

     

    Last login: Tue Dec 10 19:42:05 on console

    Ms-iMac:~ m$ sudo nvram SystemAudioVolume=%00

    Password:

    Ms-iMac:~ m$ sudo nvram SystemAudioVolume=%00

    Ms-iMac:~ m$

    -----

    If you are still having problems go to an apple store and counsult a genious.

    believe it or not, people should complain forever if a problem does not get solved. Perhaps you`ve realized that your "solution" does NOT work for everybody

    The thread and complaining will continue until the stupid startup gong is gone forever.

    Then go to terminal and type one of the above. I do it on all my systems and it works fine.

    Did you actually try it?

    Did you go to an Apple store?

    I've tried the suggested command,

     

    sudo nvram SystemAudioVolume=%00

     

    and been successful, in some cases.  On other computers, I have tried it, and it has failed, in spite of trying it repeatedly.  This variation doesn't seem to depend on the age of the computers.  Other postings in this thread and elsewhere, suggest the need for quotation marks around the data following the equals sign, hence,

     

    sudo nvram SystemAudioVolume="%00"

     

    This version has also worked for me at times, and failed for me at other times. 

     

    Perhaps Daling or someone else can answer a procedural question for me.  I normally work in a standard account, switching to my admin account only when necessary for a handful of installs or other tasks that won't allow authenticating with an admin password from a standard account.  Issuing one of the above commands is one of the times when, I believe, I have to be logged into an admin account.  Is there a way to run this command as a standard user, and authenticate with an admin login name and password?  Or is switching accounts always required, for those of us who normally run standard accounts?

    If you look at my post terminal prompts you for the admin password.

     

    Here is what you see in terminal:

     

    Last login: Tue Dec 10 19:42:05 on console

    Ms-iMac:~ m$ sudo nvram SystemAudioVolume=%00

    Password:

    Ms-iMac:~ m$ sudo nvram SystemAudioVolume=%00

    Ms-iMac:~ m$

    -

    I am logged into an account with admin privlidges at this time. Should not matter but you can try it this way. Note after the login prompt I did repeat the command.

     

    Try %10 instead of 00.

    You say sometimes works and sometimes does not. Is there a pattern?

    In my experience, it DOES matter whether I am logged in as admin or standard.  When I am logged in as admin, I see what Daling posted above.  When I am logged into a standard account, after entering the password into Terminal, (after the first two lines as in Daling's post) I see:

     

    Password:

    kgb is not in the sudoers file.  This incident will be reported.

    kgb-3:~ kgb$

     

    I get this result whether I use the password of my standard account or the password of my admin account.  Perhaps there is a way to enter both the admin login name and the admin password, but I don't know it.  Maybe someone can enlighten me.

    Hello all,

     

    I am afraid it doesn't work on my iMac27 Alu with Mavericks installed. Tried all the commande lines with all % (all all the 3rd pary tools). Still this horrible annoying sound...

     

    Apple, why are you doing this to us!!! If you REALLY want us to hear something at boot, put a gentle peacfull little bing, not this agressive robotic fart!

    Try looking at Onyx.  Granted I have an older Imac but it has been working with Mountain Lion.  Under the Mountain Lion version of Onyx under the "Parameter" tab and then under the "Login" tab way at the bottom is an option for "Startup Sound".  Turn it off and you should be good to go and not hear it anymore.  It's been working perfect on my Imac for over several months now.  Onyx is free too.  I don't know what version of OSX you are using but it should work with any version from Mountain Lion on back.  Don't know what the version of Onyx does under Mavericks so if that is what you have that option may not be there.  Here is the link to the different versions of Onyx;       http://www.titanium.free.fr/downloadonyx.php

    Hello Johnny,

     

    Thanks for the suggestion, but here also, with the latest version of Onyx, despite the fact that option exits at the location you specified, it just doesn't work. I am just getting desperate of getting rid of this horrible sound... Can someone from Apple pitch in here giving the amount of people complaining so hard?

    I know how frustrating this can be!  I have tried various suggested solutions (such as Onyx and others) without real results.

     

    I did run across this discussion reply in mid-2012.

     

      http://hints.macworld.com/article.php?story=20120513121111656

     

    I use external spreakers. Through the instructions supplied, I am able to lower the gong volume considerably. Now there is no LOUD gong at startup, only a minimal gong sound...

     

    It is an option to consider.

     

    Bob
