Give Microsoft Teams its own notification sound on your Mac

Why Teams is easy to tune out

macOS plays one alert sound for everything and only lets you switch an app's sound on or off — not change it. So a Teams ping sounds like every other notification, and Teams sends a lot of them: channel posts, replies, reactions, mentions, and calls all arrive the same way.

When it all sounds identical, you either tune Teams out entirely and miss the message that mattered, or you stop and check every time. Neither is great.

What you can do without TrillMark

• Teams' own notification settings. Teams has detailed controls — you can set channels to notify you for all activity, mentions and replies, or off, choose whether banners appear, and mute specific chats. This is the most important step for cutting volume. But every alert that gets through still uses the one Mac sound.
• System Settings › Notifications › Microsoft Teams. Toggle the sound on or off and pick banner vs. alert. No custom sound.
• A Focus. Silence Teams during focused work — but that hides it rather than making it recognizable.
• Scripting tools. Hammerspoon or Keyboard Maestro can react to notifications, but they're a lot to set up and maintain just to hear Teams differently.

How TrillMark makes Teams cut through

TrillMark reacts to the notification banners macOS already shows. Add Teams, give it a sound you'll recognize and a color, and every Teams notification arrives as a sound you know plus a flash labeled “Microsoft Teams,” so you can tell it apart at a glance.

Because TrillMark can read the notification's text, you can add a rule that plays a louder, unmistakable sound only when a message @mentions you or when it's a call, while routine channel activity stays soft or silent. Combine that with Teams' own per-channel settings and the pings that matter finally stand out.

The text is read only on your Mac, only to decide how to react, and never leaves your machine.

Set it up in about a minute

1. In Teams, set noisy channels to mentions and replies only (or off) so fewer alerts get through.
2. In TrillMark, add Microsoft Teams and give it a sound you'll recognize — preview tones right in the list.
3. Pick a color for Teams and choose a full-screen wash or a quiet edge band; TrillMark labels the flash with the app's name.
4. Add a rule for “when the message contains my name” with a louder sound, so @mentions and calls stand out.
5. Turn off the system sound for Teams in Notification settings so you hear only the sound you chose.
