Death to the Start-Up sound!

How do I turn off the start-up sound?

The chime is the equivalent of BIOS beep codes you hear on standard X86 hardware that uses BIOS. When things are wrong, you will hear different tones. The chime just indicates that all standard tests have passed.
Most Macs are designed to "sleep" instead of be shut down entirely, and by that line of logic you aren't constantly powering the unit up and down, so the chime won't be heard as often as it otherwise would be.
However, the chime CAN be silenced without additional software by holding down the mute key on a standard Apple keyboard, or the F3-key I believe it is, on Apple notebooks while pressing the power button. This setting is not saved, but per-session, so you'll have to do it everytime you power-on if you never want to hear the chime again.

  • Is there a way to shut off the start-up sound?

    how do I turn off the start-up sound that plays when I turn on my macbook?

    Try downloading Psst from www.macupdate.com. There is also another, called something like startupchime.prefpane or something like that. Look around macupdate using words like chime and startup chime, and you'll find a way.

  • The Start up sound - shutting it of?

    Hi!
    I've got a MacBook and I really want to know how to cancel the start up sound. You know, you turn the power on, the screen is lit, you hear som mechanic noises from the machine waking up and then Boom the starting sound of Doom let's everyone know Jakob has just turned his notebook on. Mostly irritating and a bit embarrassing when sitting in a quiet study hall.
    Have a good one
    Jakob
    (oh and turning the sound all the way down doesn't help)

    Cheers mate

  • Silence the start up sound?

    I often find myself in the library wanting to use my macbook but i always know the last time i had it on i had the volume turned up and so when i press the power button that beautiful start up sound will come blaring out of the speakers which is really quite embarassing when everyone else is in silence!
    is there a way to stop the start up sound playing without having muted the volume the previous time i used it?
    (i don't want to turn the start up sound off completely just when i'm in a quiet place!)

    hmm... people don't really seem to be understanding

  • Mute the start-up sound!

    I just had my MAC in for a repair at the Apple store and now that I have it back home, I noticed that  on start-up, the start-up sound plays through the built-in speakers. I do not remember how to turn off that one sound. I do not necessarily want to turn off all system sounds. Is there a way to just turn off, or mute the start-up (and other individual system sounds)?

  • Is there any way to mute or eliminate the start up sound?

    Loud Start Up Sound of Mac OS 10.4.11 drives me nuts!
    It wakes up the babies in the neighborhood and starts the dogs barking.
    Is there any way to prevent the start up sound from being produced? Mute it?
    Reduce it?
    (The sound volume controls on the keyboard and in the Sound Preference Panels
    seem to have no effect on it.)

    Hello,
    Just so you are aware, the startup chime is there for a reason. It means all is well with your Mac, but if you wish to silence it go here; http://homepage.mac.com/geerlingguy/macsupport/mac_help/pages/0025-startupsound.html
    And just in case the above link isn't what you want go here; http://www.versiontracker.com/dyn/moreinfo/macosx/21378
