How to change the volume of one app on Mac
Turn a loud game down without touching your music, or make a quiet video call louder — one slider per app.
macOS can’t do this on its own: the volume keys and Control Center change one volume for the whole Mac. MacFixes adds a volume slider for every app that’s playing sound, from silent up to 200%.
What macOS gives you
One system volume, on the volume keys and in Control Center. A few apps have their own slider inside their window — Music, Spotify, most video-call apps — but most apps don’t, and there’s no single place to set them all. So a game, a call and your music get louder and quieter together.
How MacFixes fixes it
- 1Add the fixOpen MacFixes Settings → Sound and add “Volume per app”. Fixes are off until you add them.
- 2Allow audio oncemacOS asks once for permission to capture system audio, which is how MacFixes adjusts each app.
- 3Drag a sliderEvery app playing sound gets its own slider in the menu bar panel. Above 100% boosts an app that’s too quiet.
Questions
Does macOS have a volume mixer?
No. macOS has one volume for the whole Mac. Some apps have their own slider, but there’s no place to set every app’s volume.
Can I make a quiet app louder?
Yes. Each app’s slider goes up to 200% for apps that are too quiet even at full volume.
Can I send apps to different speakers too?
Yes — that’s a separate fix, Output per app.
