Mute the Mac Boot Chime with StartNinja for OS X Lion

Jan 26, 2012 - 23 Comments

StartNinja for OS X Lion mutes the boot chime on Macs

Macs have always had the classic boot chime that announces the system has begun startup or has rebooted, but if you’re in a quiet place you don’t always want that sound to play. You may know that you can temporarily mute the Mac by holding down the Mute key during boot or reboot, but if you are looking for a more permanent solution that doesn’t involve the terminal, check out StartNinja.

A free and simple utility that gives users the ability to disable the startup chime, StartNinja will keep the Macs boot sound quiet while allowing the Mac to retain normal sound function otherwise.

If you’re interested in getting StartupNinja to silence your Mac startup chime, you can download it from the developer here:

This should work on all modern Macs to hush that boot volume, though it’s OS X version dependent, so older OS X versions will want to rely on a different app.

For those running Mac OS X 10.6.8 or prior, holding mute works on a per boot basis, or there is a system preference panel that gives the same ability to disable the boot sound.

    Both utilities (StartNinja and post) work on my iMac with OS X 10.8.2 (Mountain Lion). But only if I have not plugged in the headphones. If I have headphones plugged in, the iMac plays “ta-dam!” on boot. And it plays it from internal speakers!

    Installed Startninja on my Mac 10.7.4 and it doesn’t always work :( once in a while the chime would still go off again and wake up the whole neighborhood. Very annoying…

    You really do need to turn it of when working in a library, or trying to take notes in a lecture, or just trying not to wake someone up.

    Why would you want to do this? The whole point of it is to tell you if your mac is working correctly.

    • Ted says:

      some people travel Alex, and some people run studios. you can always if it passes boot procedure by the Apple logo and spinning wheel.

    it did not work on my Mac Pro

    Did not work on my iMac.

    Startup Sound preference pane sets a volume that applies only to the startup chime:

    I use it with Lion 10.7.2 and Snow Leopard 10.6.8

    • John says:

      Make sure you download the beta, not the “latest stable release.” The “stable” release installs, but won’t work on an Intel-based Mac. Neither will the uninstaller.

    I’m so terribly happy I’m still on Snow Leopard. StartNinja looks awful, just look at it. Since Apple made iCal and Address Book look ridiculous people seem to think they can do to the user interface whatever they like to do—as if they are on MS Windows.
    Snow Leopard StartUp Sound’s aesthetics are much better, although not perfect either because of the way the credit line is crammed in.

  11. Tim says:

    I haven’t tried StartNinja, as I use Snow Leopard. However, “Psst” has been the most reliable program I’ve found, and it works in Snow Leopard or Lion:

    Nice utility, but not planning to use it..I love the boot chime!

  13. Pippox0 says:

    I don’t think , because chime is inside efi bios …

  14. Justin says:

    Is there a way to change the boot chime to something else?

  15. Les says:

    StartNinja is awesome! And it works!

  16. haroon says:

    There is also “auto mute”

  17. icebreaker says:

    Start ‘ninja’…good one :)

  18. uuwalnut says:

    Is there a command line instruction that can do the same thing?

    Awesome site.

  19. Kenov says:

    Alternatively, you can mute your computer and after the restart/ new start you will not hear the chime.
