MicLock

Your Mac keeps its mic.

Stops Bluetooth headphones from stealing your microphone.

When Bluetooth headphones connect, macOS switches your microphone to the headset's, and the sound quality drops. MicLock gives the Mac's own microphone back in less than a second. It lives in the menu bar with no Dock icon.

Free

• Restores the Mac's microphone in under a second when a Bluetooth headset connects
• Never touches USB microphones or audio interfaces: only Bluetooth is "fixed"
• Menu bar only, no Dock icon

Requires macOS 14 or newer on Apple Silicon.
