Microphone and audio device authorization for Piezo

MacOS requires applications to obtain user approval to access audio from microphones and other audio input devices. This page details how this works with Piezo.

Requesting access

The first time you attempt to stream audio from an input device with Piezo, the system will show a dialog confirming that you wish to provide access:

Click OK in that dialog to enable Piezo to access your input device. It will then be able to stream audio from the device, according to your configuration.

Fixing access issues

If you deny the system's request to provide Piezo with access to your input device, Piezo will be unable to stream audio from your audio device. If you attempt to stream this audio, you'll receive a warning message:

To fix this issue, you must provide Piezo with the ability to access your input device. Follow these steps:

1) First, quit Piezo.

2) Next, click the Apple () menu in the upper left of your screen, then select System Preferences.

3) Click the Security & Privacy option, then click the Privacy tab and select Microphone from the list on the left.

4) You should see Piezo in this list, with its checkbox unchecked. Click that checkbox to provide Piezo with the necessary access to stream from audio devices.

5) Now, re-open Piezo and transmit from your input device again. This should now work as expected.
