Silent Start is now completely free!

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

A real life saver

I cannot understand why Apple does not make all sounds optional (on/off), but then the more I learn about Apple products, the less impressed I am with their software. Nice hardware (if exceedingly expensive); weak software.

In any case, this app made my day. The silly startup chime should have died ~20 years ago, but for some reason Apple has kept it around. Possibly it's to give customer the sense that these computers are not intended for serious work.

Turning off the chime was a simple matter of installing this app and making sure "Mute startup chime" was turned on. That's it!

I give it 4 stars instead of 5 because I haven't tested it with different OS "upgrades" yet, or under different scenarios with my headphones on/off. But those seem like easy things to fix, one hopes.

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.

Works but there is a problem (Update)

After installing this app I had trouble with my computer restarting on it's own after going to sleep. I thought I had a virus or malware and spent the better part of a day checking that out. The computer continued to reboot. After uninstalling this app I haven't had a problem.
Update: it wasn't this app that was causing my problem. It is still rebooting in sleep mode. Sorry for the confusion.
