Does anyone know why every operating system needs an annoying startup sound? My guess is it is included to scare the crap out of the cat. I could be wrong. Anyways here is how you get rid of it on your Mac.

  1. Goto Arcana Research and download StartupSound.prefPane.
  2. After you download it, install it.
  3. Go to Preferences > Startup Sound and check the Mute check box.
  4. Make sure “Turn on start up volume control” is checked as well.

StartupSound.prefPane

That’s it. For me, it took a couple of reboots before it took effect.

As for the cat.. It’s doing much better. Thanks.
