Keep alerts out of your Premiere Pro or DaVinci Resolve edit on Mac

When you edit video on a Mac, one Slack ping over your dialogue is enough to break the take — and the volume keys are no help, because they drop your timeline right along with the notification. Premiere Pro and DaVinci Resolve can't hold their own playback loud while alerts and music go quiet: macOS blends every app into one output, and each editor only steers its own share of it. The answer is per-app volume. Fader hands each app a fader of its own, so the edit stays put while notifications drop, and you ride the balance with letter keys instead of leaving the timeline.

If you cut video on a Mac, you know the interruption. You've set your monitoring to a comfortable level, you're deep in a scene, and a notification chimes over the dialogue you're trying to hear. The reflex is the system volume keys — but that master control moves everything at once, editor playback included. Turn it down to silence the alerts and your timeline goes quiet with them. There's no native "Premiere at 100%, notifications at 20%" on macOS, and switching editors doesn't help: Resolve behaves the same way.

Why the editors' own audio controls don't solve this

Both apps have serious audio sections, so it's tempting to assume one of their controls is the answer. They're built for a different job — mixing your project — not for balancing the editor against the rest of your Mac.

• Clip and track levels. Dragging a clip's volume line in Premiere, riding a Fairlight track fader in Resolve, or applying track gain is edit gain. It changes the level that renders and exports. Pull it down just to monitor quietly and you've altered your mix — not what you want.
• Audio meters. The meters in the Audio Track Mixer or on the Fairlight page are for watching levels so nothing peaks past 0 dB. They read the signal; they don't set how loud playback comes out of your speakers relative to other apps.
• Audio hardware / output device. Premiere's Audio Hardware preferences and Resolve's video/audio output settings pick which device the editor sends to. Useful for routing to an interface, but the audio still leaves at the system's level. It's a destination switch, not a volume that sits apart from macOS.

DaVinci Resolve does go one step further than Premiere here: its Fairlight page has a Control Room monitor level (with DIM and MUTE) that sets how loud you hear playback without touching your edit. That's genuinely useful — but it only governs Resolve's own output. It does nothing to Slack, Mail, a browser tab, or the music you had on for the boring parts. The gap is the same in both editors: none of these controls can pull your other apps down while leaving the editor where it is.

What "playback vs alerts" really means

The distinction worth naming: your edit's levels (baked into the file) are separate from your monitoring level (how loud you hear it while you work), and both are separate from everything else on your Mac — notifications, music, chat, a reference video in the browser. The editor handles the first. Resolve can handle the second for itself. macOS gives you one knob for the third, shared with the editor. What's missing is a way to say "keep the timeline where it is, and drop the alerts," without muting notifications one Focus toggle at a time or quitting every other app.

The real fix: per-app volume at the macOS layer

To hold Premiere or Resolve at one level while alerts and music sit at another, you add per-app volume — a mixer that works at the OS audio layer and gives every running app its own slider in one place. That's the only approach that leaves your edit untouched and keeps the system master out of it. A few options exist, and they differ mainly in how fast you can reach the control while you're working.

A note on what the editors themselves cost, since it changes the calculus. DaVinci Resolve is free in a genuinely full version (no watermark, no time limit), with Resolve Studio a $295 one-time perpetual license if you want the extras. Adobe Premiere Pro is subscription-only — around $22.99/month on an annual plan billed monthly, and higher month-to-month. Either way, the alerts-over-playback problem is a macOS limitation, not something a pricier editor tier removes. SoundSource by Rogue Amoeba is a capable per-app mixer with EQ at $49 one-time; Fader is $19.99 one-time with a 3-day free trial. All of them do the core job — the difference an editor feels day to day is how quickly you can nudge a level without breaking flow.

Why the keyboard matters when you're deep in a timeline

When you're editing, your hands are on the keyboard and your eyes are on the cut. A menu-bar mixer means leaving the timeline: mouse to the menu bar, click the icon, find the editor's row, drag its slider, click away, and find your place again. That's a real interruption when it happens every few minutes — which, with notifications, it does.

Fader's whole idea is that the fastest controller you own is the keyboard already under your hands. You hit a toggle hotkey and the keyboard becomes a mixer — one letter column is Premiere or Resolve, the next is your music, the next is Slack — so you push the alerts down or bring the editor up with a keystroke and go straight back to cutting. You can also bind a per-app mute key, so "silence notifications" is one keystroke from inside the timeline. For a task you repeat all day, that's the gap between a mixer you own and a mixer you actually use.

Routing is the related trick: send the editor somewhere else

Sometimes the cleaner answer isn't quieter, it's elsewhere. Monitor Premiere or Resolve on your headphones or interface while notifications and music stay on the laptop speakers, and the balance problem mostly disappears. Each editor can pick its own output device, but per-app output routing for your other apps — keeping them on a different device from the editor — again needs a third-party tool, because macOS routes every app to one output by default. If that's your setup, see how to send an app's audio to a different output on Mac. The approach here is the same one that solves the sister problem for Apple's editor — Final Cut Pro playback volume vs system audio — so if you switch NLEs, the fix travels with you.

Bottom line

Premiere Pro and DaVinci Resolve mix your project beautifully, but neither can keep its playback steady while your alerts and music drop — macOS hands every app one shared output, and the editors only control their own side of it. Resolve's monitor level is a nice extra for hearing Resolve, and nothing more. For a real balance you set once and reach in a keystroke — timeline at one level, notifications at another, without ever leaving the cut — a per-app mixer is the fix. If reaching the control fast is what matters while you edit, that's exactly what Fader is built for.
