Mute Chime iMac Mavericks
Aside from muting the sound via the keyboard before turning off the computer - which I never remember, is there a way to mute/disable the start up sound in Mavericks OS?
I did a search of this forum and did not find anything for Mavericks. I used to use TruePreview but it does not work in Mavericks.
For iMac users who don't want to hear the startup chime I have found a simple and permanent solution: mute the internal speaker and monitor sound through the headphone port or an audio interface (plugged into in the thunderbolt or USB port).
First, just a little background: Unlike many laptops, plugging something into the headphone (audio output) port of my iMac does not stop the chime, because the internal speakers continue to play the chime. However, you can control the sound of the internal speakers separately from the headphone port. If you mute the internal speaker it stops the chime.
Like many people, I always listen to the audio of my mac either through a sound system or headphones plugged into the headphone port (or else through an audio interface plugged into the thunderbolt port). So muting the internal speaker doesn’t affect me; I can still hear audio. Also, I don’t have to constantly mute and unmute anything, or put any code into the system.
How to do this: When you have nothing plugged into the headphone port the system preferences for “Sound” let you mute the internal speakers. Be sure nothing is plugged into your headphone port. When you have something plugged into the headphone port the system preferences will allow you to change the settings for the headphone port only, and not the internal speakers. (By the way this seems like a confusing set up. Why not have these in the same menu at the same time?)
