PERSISTENT INPUT
Lock your Mac microphone with priority and fallback

AIRPODS
Stop AirPods using the microphone on Mac
Listen through AirPods while keeping a built-in or external microphone selected for input.
DICTATION
Fix Dictation using the wrong microphone
Choose built-in Dictation’s separate microphone source in Keyboard settings.
APP OVERRIDE
Mac app using or changing the wrong microphone?
Check whether the app is pinned to a device, following the system default, or changing it.
PRIVACY & SOUND
Microphone permission versus selection
Permission decides whether an app may access a microphone. Selection decides which one it uses.
The choice should stay chosen.
Mic Check protects a ranked list of Mac inputs. If another device takes over the system default, it restores the highest-ranked connected microphone.
