If you can’t record audio from an external source on Mac
To record audio from an external source using an audio input like the built-in mic on your Mac, an external USB microphone, or an external audio interface, check that the app you're using has access to the audio input on your Mac.
When trying to record, an alert might say that audio input isn't accessible. Or you might not hear sound, see waveforms, or see audio meters move when recording. This can happen if you the app you're using to record audio doesn't have your permission to access audio inputs.
