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

It does not always work

This app could be better. It does not always work. If you forget to unplug your headphones, or if the system thinks that the headphones are still plugged in, when you shut down then the chime will sound again on the next reboot.

Problem with running update

In high SIerra I am not seeing an icon for silent starton on my bar. The update would fail everytime I launched it as well. And I do not get any kind of interface from the launcher. Anyway it kept nagging me to update it so I did the following and now it is launching the correct version on boot up and no longer nags me. Still can’t get any kind of menu or icon on my bar but at least it is no longer nagging me for an update and when I check the version it is the latest: Launch go from the finder, computer, applications, right click on silent start, show package contents,moven contents folder to the trash, reboot,go into the App Store, install silent start.

Doesn't work

I've read everything I could about this app, because it hasn't worked once since I downloaded it last week. The app said not to shut down your computer with headphones in, because that will prevent it from working, so I tried that and it still keeps making the noise at startup... except now it also makes it when I have my headphones plugged in. I'm starting to think there's basically nothing that can prevent the startup chime from going off.
