Audio Hijack’s Permissions window

Microphone Access (Optional)

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

Relaunching To Provide Microphone Access

If you’ve previously denied Audio Hijack 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 Audio Hijack, then grant permission when the application relaunches.
