MicMüter

MicMüter is a very simple app that runs in the menu bar that lets you toggle your Mac’s built-in microphone on and off - effectively making it a microphone kill switch. In a world where many of us spend much of our time video conferencing, this can be really useful if you need to mute yourself quickly.

• Use a global hot key to quickly toggle your Mac’s microphone on and off (accessible from any app)
• Choose from one of several hotkey combinations
• Choose to also display your microphone's status in a clickable, floating window
• Choose whether or not to play an audible confirmation
• Choose whether or not to run MicMüter each time your Mac starts up
• A signed and notarized native application
• Very lightweight and uses minimal system resources
• It’s free. Similar tools cost money!
