    I recently purchased a new mac (wish i didn't to be honest as it's a been a pain in the a$$ (especially with ML and it's narcolepsy issues)

    On my old mac I can't recall how i killed the startup chime but on my new one I've tried entering commands into the terminal and that didn't work. I also tried the ninja and that didn't work.

    I must be missing something, why does the ninja work? Why doesnt the command work? This si the command I used from a tutorial off the net

    sudo nvram SystemAudioVolume=%80

    Is it too much to ask for a computer that will actually do what I want it to do?

    Frustrated to the max!!

    Any assistance would be greatly appreciated.

    I think if you mute before shutting down it does not chime during boot.
    Did you try that already?

    Try replacing the "%80" with "%00" making the command read like this:

    sudo nvram SystemAudioVolume=%00


    Hope this helps,

    Edit: Also, what version of ML are you running?

    As others said, the current sound settings get saved when you shut down. So if you mute the audio or turn it way down, thats what the startup chime will be.

    However, the settings it uses are the internal speaker audio settings. If you use a USB audio output like I do, it won't use those settings. To affect chime volume, go into the system preferences, set the output audio to internal, set volume way down or muted, then switch output audio back to desired.

    There are also various third partys hacks to force it if you still use internal sound but want the startup chime muted. This one seems promising: http://www.cultofmac.com/200772/silence-your-mac-boot-startup-sound-altogether-os-x-tips/

    thanks for your feedback guys, this is the only way it seems to work on my mac:

    If you have headphones connected to your Imac but still hearing annoying startup sound, try following steps:

    1. open "System preferences", Sound and "Output" tab

    2. Unplug your headphones and watch "select a device for output" list

    3. After a while there should be appearing "Internal Speakers"

    4. Check "mute" checkbox from bottom

    5. Plug your headphones back, mute checkbox shold change back to unchecked


    now startup sound should be muted

    Jumping in as I'd like a different setup if anyone knows if it's possible.

    I switch between internal speakers and a USB headset a lot. I'd like the startup chime to be always heard on the internal speakers on boot, regardless of what my sound settings are.

    Possible?
