Ever wish you could mute the startup sound your Mac makes when it boots up? At the very least, perhaps you want to turn the volume down a bit on the startup chime? You’ll want to take a look at StartupSound.prefPane, from Arcana Research. The system prefs pane does two things, it either mutes the sound, or allows you to adjust the volume. That’s it. Thankfully, it does those two simple tasks perfectly, and absolutely FREE! You can download StartupSound.prefPane here. Be sure to grab the latest version if you use an Intel Mac.
