••• We're happy to announce Silent Start is now free! •••

Ever had to restart your Mac and you (or someone else) has been annoyed by the startup chime? If so, give Silent Start a try today. It's able to silent the chime and then restore the volume back to normal after it starts up.

The only exception is if headphones are plugged in, and in that case macOS doesn't allow Silent Start (or any other app) access to the internal speakers. However, Silent Start will show a helpful dialog right before restart/shutdown to give you a chance to unplug them so it can mute the startup chime.

We love hearing from our customers, so please feel free to email anytime for support or comments at

What’s New

Version 1.1.7

[New] Menubar icon! This was a highly requested change so we hope you like the new one.
[New] Using a toggle button in the menu to easily and quickly show the status of the startup chime muting.
[New] Added option to not show the confirm quit dialog again.
[Improved] The notes for the feature to show an alert on shutdown so it's clear about why the dock icon/menubar need to be shown.

Works Perfectly

No fuss to use. I’ve been wanting something like this and I’m glad I found this app.

I did wonder why the dock icon could not be removed, but the answer was simply explained on the support site’s FAQ page.

Works Like a Charm

Works perfectly on my iMac running macOS Sierra 10.12.6. No longer does my computer start-ups awaken my wife in the wee morning hours. *Note that I have my "Silent Start" Preferences set as illustrated in screen shot #3. Thank you Turnabelly Software Inc.
