Permissions

Airfoil’s Permissions window is shown on first launch, and can also be accessed from the Airfoil menu. It lists both required and optional permissions. For the best experience, we recommend enabling all permissions.

Airfoil’s Permissions window

System Audio Access Required

System audio access is required for Airfoil to operate, and you’ll be prompted to grant permission the first time you launch the app. This permission enables Airfoil to capture audio from other applications running on your Mac.

Microphone Access Optional

To stream audio from a microphone or other input device, Airfoil must be granted permission with MacOS. If Airfoil does not have microphone access when you attempt to stream from an input device, it will request it.

Relaunching To Provide Microphone Access

If you’ve previously denied Airfoil permission to access your microphone, you’ll see the following dialog when you try to enable the permission, or attempt to capture from an input device.

Click Relaunch Airfoil, then grant permission when the application relaunches.
