    there a way to stop the Mac startup sound?
    I am the very proud owner of a new 27" iMac, and so far, so good, though I do have one minor niggle,

    When the Mac boots up, you get what I can only describe as "Taa Daa" sound, and this happens even when I have external speakers plugged into the audio out, with the external speakers turned off. Is there a way to stop the Mac making this start up sound through its own speakers?

    There are probably other ways to do this but here is what I used to use Download StartupSound.prefPane for Mac - Control the volume of the startup chime. MacUpdate Mac System Software Downloads. I haven't used it in a while but the last time I did it worked well.

    The "Startup Sound Preference Pane" still works well and has even been updated to support Snow Leopard. I use it and have been using it since Leopard.

    Turn the volume down to "0" before shutting down... works for me!
