Silent Start

Silence your Mac's startup chime

Stacks Image 28797

Requires macOS 10.10 or higher

Have you ever had to restart your Mac and you (or someone else) has been annoyed by the startup chime? If so, download it for free and give it a try. 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 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 with no registration required, and fully compatible with macOS 10.14 Mojave, including the system Dark Mode.
