Mic Mute for macOS

A system-wide mute for macOS microphones with a global shortcut and visual confirmation of mute status. Inspired by VCM for Windows.

Mute with Cmd Shift A or from the system tray dropdown. This is configurable from a settings file in ~/Library/Application Support/mic-mute/settings.json.

Features

• CoreAudio API mute input devices
  • Mute input devices
    • Note: Some virtual devices may be unable to mute for now
  • Provide global hotkey muting
  • Poll new devices to mute while microphones should be off
• Visual confirmation of mute status
  • Show microphone mute status in system tray
  • Show microphone mute status in small popup window
  • Popup window shouldn't appear in screenshots or recordings and ignores mouse events
  • Popup follows screens and monitors with cursor
• Report whether camera is in use (disabling cameras appears to be impossible or too difficult for the scope of this project)
• Add configurable settings (hotkey, startup)
• Open app on system startup

Releases

I have not elected to sign the app by joining the Apple Developer Program. The releases have been self-signed by me and can be installed by bypassing the typical app security on macOS. You're also welcome to build and bundle the app yourself with the simple instructions described below.
