If you can’t record audio on a Mac using macOS Mojave or later

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 when you're recording audio using your computer's built-in mic, an external USB mic, or the inputs on an external audio interface.

Depending on which macOS you're using, follow these steps to allow the app to access audio inputs.

1. Quit the app you're using to record audio.
2. Choose Apple menu  > System Settings, then click Privacy & Security.
3. Click Microphone.
4. Turn on the setting for each app that needs access to the built-in mic, an external USB mic, or the inputs on an external audio interface.
   
5. Open the app and try to record audio again. 

If you're using an external mic or audio interface to record audio and it's still not working, check with the manufacturer of your device for software updates and information on compatibility.
