How to set Apple Music's volume independently of other apps on Mac

Apple Music's volume slider on a Mac isn't truly independent — it rides on top of your system volume rather than replacing it. Move the slider and you're setting Music as a percentage of the master output, so the Mac's volume keys still drag Music around and Music can never play louder than your current system level. To give Music its own volume against your calls, browser, and everything else, you need a per-app mixer that puts Music on its own channel at the audio layer.

It's an easy thing to get wrong, because the Music app looks like it has an independent control. There's a slider right there in the player at the bottom of the window. Drag it down and, sure enough, the music gets quieter. So why does turning your whole Mac down also pull the music with it? Because that slider and the system volume aren't two separate levels — they're stacked.

What Apple Music's slider actually does

The slider in the Music window is a relative control. It multiplies against your Mac's system output instead of standing on its own. If your system volume is at 50% and you set Music's slider to 50%, the music plays at roughly 25% of full — half of a half. Apple's own support note spells out the ceiling: the maximum Music volume is limited by your computer's volume setting. Music can duck below the system level, but it can never climb above it.

That's the whole reason it doesn't feel independent. Two things you'd expect from a real per-app control simply aren't there: you can't push Music louder than the rest of your Mac when you want it out front, and you can't stop the system volume keys from moving it. Both of those are baked into how the slider works.

Why the volume keys don't help

On a Mac, the F11/F12 volume keys (and the Control Center slider) move one master output level that sits in front of every app at once. There's no built-in way to say "these keys control Music and nothing else." So when a track comes on too loud during a call, tapping the volume keys turns down the call, the browser, and your notification sounds right along with it. This isn't a Music quirk — it's how macOS handles volume for everything. We wrote up the full reason the Mac shares one volume across every app if you want the background.

The free half-measures (and where they run out)

You can get partway there without spending anything. None of these give Music a true independent level, but depending on what you're after, one might be enough.

Set the balance by hand. Turn your system volume up to where your loudest app (say, a call) sounds right, then pull Music's own slider down until the mix feels balanced. This works because Music can duck below the system level. The catch: it breaks the moment you touch the volume keys, and you have to redo it every time the system level changes.

Use a keyboard utility aimed at Music. Free open-source tools like Volume Control remap the volume keys so they drive Music's internal slider instead of the system output. That's genuinely handy for keyboard control of Music, but it's still the same relative slider underneath — Music still can't exceed the system level, and it only knows about Music, not your other apps.

Lean on the other apps' sliders. If your goal is really "Music quieter than my call," you can turn down the call app instead. That works when every app in the mix happens to have its own slider — and falls apart the moment one of them doesn't.

The real fix: give Music its own channel

To set Music's volume independently — louder or quieter than everything else, and immune to the system volume keys — you need a per-app mixer that sits at the OS audio layer. Instead of stacking on top of the master output the way Music's slider does, it gives each running app, Music included, its own true level. Set your system volume once for your calls and browser, then hold Music wherever you want it. Turn the Mac up or down and Music stays put relative to the rest, because it's no longer riding the master.

A few tools do this. They differ less in whether they can set Music's volume on its own and more in how fast you reach the control — which is what decides whether you actually use it during a track or forget it's installed.

Background Music is free and open source, and it will give Music its own line in a menu-bar list — a solid choice if free is the priority and you don't mind reaching for the mouse. SoundSource from Rogue Amoeba is a deep, polished menu-bar app with per-app EQ and routing on top of volume, at $49 one-time. Fader takes the volume-and-speed angle: a one-time $19.99, and the control lives on your keyboard.

Why the keyboard matters for music

Volume for music is a thing you ride, not set once. A track comes on hot, a quiet acoustic number needs a bump, a call starts and the music has to drop fast. With a menu-bar mixer that's: go to the menu bar, click the icon, find the Music row, drag it, dismiss. Five actions, every time.

Fader's bet is that the fastest controller you own is already under your hands. You hit a toggle hotkey, the keyboard becomes a mixer, and one column of keys is Music — tap to nudge it down, tap to bring it back, bind a mute key to kill it instantly when a call connects — without leaving whatever you're doing. You can also push Music past 100% with a boost when a quiet track needs to cut through. For something you adjust this often, that's the difference between owning a mixer and actually using it. The same approach works for controlling Spotify's volume separately if you run both.

Bottom line

Apple Music's slider looks independent but isn't — it's a relative level stacked on your system volume, so it can't beat the master and the volume keys still move it. For a quick balance, drop Music's slider by hand and leave the keys alone. For a Music level that holds its own against every other app, survives the volume keys, and can even push louder when you need it, a per-app mixer is the fix. If reaching that control in a single keystroke is what you care about, that's exactly what Fader is built for.
