Give PagerDuty an alert you can’t miss on your Mac

Why a page can sound like a Slack ping

On call, the whole job is not missing the page. But a PagerDuty desktop notification uses your Mac’s one alert sound — the same chime as a Slack message or a calendar nudge — and macOS only lets you turn it on or off.

So the single most consequential notification on your machine is also the one that’s hardest to tell apart, and the easiest to miss if you stepped away or muted your Mac.

What you can do without TrillMark

• PagerDuty’s own escalation. PagerDuty’s real strength is phone calls, SMS, and push to the mobile app, with escalation policies if you don’t ack. That’s the reliable backstop and you should use it — but the desktop notification itself still rides on the Mac’s one sound.
• System Settings › Notifications. Toggle the sound and set the browser or app to “Alerts” so a page stays on screen until dismissed — helpful, but not a distinct or louder sound.
• The mobile app. Your phone is the true safety net for sleeping through — but at your desk, a Mac alert you can actually tell apart keeps you off the phone.
• Scripting tools. Hammerspoon or Keyboard Maestro can escalate a page, but that’s real engineering to build and maintain for something you can’t afford to have break.

How TrillMark makes a page unmissable

TrillMark reacts to the PagerDuty banner, whether it comes from the desktop app or a browser. Give it the loudest, most distinct sound you own — TrillMark can play above 100% — and a full-screen flash in a color you reserve for incidents, labeled, so a page reaches you even muted or across the room.

Because TrillMark reads the notification, a rule can make a triggered incident louder than an acknowledgement or a resolve, so the alert that needs you now is the one that shouts.

This is a desk-side layer on top of PagerDuty’s phone and SMS escalation, not a replacement for it — and it reads the banner text only on your Mac, never sending it anywhere.

Set it up in about a minute

1. Open TrillMark and add PagerDuty (or the browser you get pages in).
2. Pick the loudest, most distinct tone and set its volume above 100%.
3. Give it a full-screen flash in a color you reserve only for incidents.
4. Add a rule so a “triggered” incident is louder than “acknowledged” or “resolved.”
5. Keep PagerDuty’s phone and SMS escalation on as the backstop, and turn off the plain system sound.
