App: Silent Start

Ever had to restart your Mac and you (or someone else) has been annoyed by the startup chime?  If so, get Silent Start for free 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, it will show a helpful dialog right before restart/shutdown to give you a chance to unplug them so it can mute the startup chime.

It's completely free, and fully compatible with macOS 10.14 Mojave, including the system Dark Mode.

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