MicButton is your physical mute button for working by voice. It lets you mute or unmute your Mac’s system microphone from your Apple Watch or iPhone Action Button without leaving a ChatGPT Voice or Codex conversation. Whether you're stepping away for a quick side conversation during a video call or working alongside a voice assistant that shouldn't hear you talking to someone else, MicButton lets you mute in an instant — right from your wrist or phone. It’s a master mute switch. MicButton mutes your Mac’s system microphone itself rather than muting inside a single app — so when it’s off, nothing running on your Mac is listening: not a call, not a browser tab, not an assistant. Your mic is off because you turned it off, and you can confirm it from your wrist without walking back to your desk. FEATURES • One-tap mute/unmute from Apple Watch • iPhone Action Button and Lock Screen control support • Live mute status shown in the Dynamic Island • Mutes the Mac’s system microphone at the source, not inside a single app • Works entirely over your local network — no internet connection required, and no audio ever leaves your devices • Lightweight menu bar app that stays out of your way MicButton is built for anyone who works from a Mac and wants mute control without breaking their flow.
