MiniMeters on macOS 14.2 and later uses a Core Audio Tap to capture the selected system output device. More info here.
Open Settings: Open MiniMeters and click Settings from the toolbar.
Select Default Output Capture: Under the Audio Source panel and choose "Default Output Capture" from the Audio Source section.
Grant MiniMeters Permission: A window will pop up requesting System Audio permissions. MiniMeters needs this to monitor outputs. You can revoke this permission at any time from System Settings.
From macOS 13 to 14.1 MiniMeters uses ScreenCaptureKit to capture desktop audio. MiniMeters disregards the video information as it is unneeded, leaving only the audio.
Desktop Audio Capture is not supported on macOS 12 Monterey and prior.
