macOS has no built-in per-app volume control. Your music is too loud while a podcast is too quiet. FineTune fixes that:
- Turn down notifications without touching your music
- Play different apps on different speakers
- Boost quiet apps, tame loud ones
- Free forever, no subscriptions
- macOS 15.0 (Sequoia) or later
- Audio capture permission (prompted on first launch)
App not appearing?
Only apps actively playing audio show up. Start playback first.Volume slider not working?
Some apps use helper processes. Try restarting the app.Input devices not showing?
Grant microphone permission in System Settings → Privacy & Security → Microphone.Control FineTune from Terminal, shell scripts, Shortcuts, Raycast, or any app that can open URLs.
