Mac Auto Mute on Unlock: Prevent Accidental Speaker Output After You Sign Back In
Need Mac auto mute right after unlock? This Default0 guide shows how to enable automatic mute for Mac when you unlock and prevent accidental speaker playback in meetings and shared spaces.
You unlock your Mac for two seconds, and sound suddenly blasts from the speaker. It happens fast, and always at the worst time.
If you are building a broader mac auto mute setup, unlock is usually one of the first rules to enable because it covers the first second back at your desk.
