New aluminum iMac, Leopard etc - any way to turn off the boot chime? Having headphones plugged in on my old G3 worked, but on this machine it doesn't and I still get the boot chime from the speakers.
Hello, Please see this MacRumors guide for an app that will allow you to change the chime behavior. Also see this thread for more background info.
UPDATE: Found a solution from http://lifehacker.com/software/featured-mac-download/silence-your-macs-startup-sound-279235.php
