How to mute your microphone on Mac with a shortcut
One key mutes every mic on the Mac — not just the one in the app you’re in — and the menu bar shows when you’re muted.
Short answer
macOS has no system-wide mute shortcut. MacFixes adds one that mutes every microphone, with an indicator so you always know.
What macOS gives you
Video-call apps each have their own mute button and shortcut, which only work inside that app. You can turn the input level down in System Settings → Sound, but there’s no single key that mutes the Mac’s microphones everywhere.
How MacFixes fixes it

- 2Record a shortcutChoose the key combination you want for mute and unmute.

This is one of 28 fixes in MacFixes.

Questions
Does it work in every app?
Yes. It mutes the microphones themselves rather than one app’s button, so every app hears silence.
