Notifications too loud.
Music too quiet.
Your Mac has one volume for everything. Volly gives every app its own, so the music can be loud while the pings stay quiet.
Three moves. All from the menu bar.

One click silences whatever keeps interrupting you. Everything else plays on.

Installed in a minute.
Volly comes straight from this site, not the App Store, so macOS asks you to approve it the first time you open it. You only do this once.
- VollyApplications
Drag it to Applications
Open the Volly file you downloaded and drag Volly onto the Applications folder.
“Volly” Not Opened
Apple could not verify “Volly” is free of malware that may harm your Mac or compromise your privacy.
Open it, then click Done
The first time, macOS may say it couldn’t verify Volly and won’t open it yet. That’s expected: click Done, not Move to Trash.

Questions
Is Volly free?
Yes. Volly is free, with no account and no subscription.
macOS won’t open Volly. What do I do?
Volly comes from this site rather than the App Store, so macOS asks you to approve it once: click Done, then Open Anyway in System Settings → Privacy & Security. The install steps show each screen.
Which Macs does it run on?
Any Mac with macOS 15 Sequoia or later. On macOS 26 it takes on the Liquid Glass look.
Why does it ask for audio recording permission?
macOS asks for System Audio Recording permission for any app that works with another app’s sound. Volly only turns each app’s sound up or down on its way to your speakers; nothing is ever recorded or stored.
Does it install a driver?
No. There are no drivers and no kernel extensions. Volly uses the process taps that Apple built into macOS.
What happens when I quit Volly?
Every app’s sound goes straight back to the way macOS plays it without Volly, all at once.
