How To Disable the Annoying Mac osx Tab Complete Alert Sound

We are a mac office here at work, and I love my mac, but they do something very annoying: beep every time you tab complete the terminal.

`ls` a directory that doesn't exist? Beep.
mv a file? Beep.
Any sort of tab complete? Beep, beep, beep.

When you fill an office with people who live inside their shell, that's a lot of beeping. It's almost as prolific as iPhone sms sounds coming from the marketing side of the room. Don't get me started on that.

So here's how to disable the annoying mac osx tab complete beep alert that you hear when auto-completing on your terminal.

Open up system preferences and click on "sound", then turn the "alert volume" all the way down. Die, alert sound, DIE!!!

Turn the "Alert volume" slider all the way down to disable the mac osx alert sound.

Be nice and mute your system or disable this sound.


  1. Finally some peace! This sound is todays version of each key beeping on the first cell phones. Cute at first, well actually, never cute. Especially not after a month or two! Thanks for the post

  2. This works too.



  3. Thank you for such a common sense solution.

  4. Thank you, thank you! I am at peace now

  5. It doesnt help. The beep beep beep does not stop. The sound is Sosumo. Turning alert volume down does not help. The only thing which helps is to restart the computer, which takes 15 minutes until the computer is normal again after a restart.

  6. Yeah! It works! Beep them off!

  7. This silenced a bell every time I hit tab in Spotlight. Thank you.
