How to change Trello's notification sound on Mac

Card and board alerts use the system sound only.

Updated · May 2026·macOS Sequoia 15.x

The honest answer: Trello doesn't expose any in-app notification-sound settings. Your real options are the macOS-level method below, or Chirpy if you want per-notification customization.

Universal approach — mute at the macOS level

macOS lets you silence any app's sound without disabling its notifications. The full visual walkthrough lives on the universal macOS method page. The short version:

  1. Open System Settings → Notifications.
  2. Scroll to Trello in the application list and click it.
  3. Turn off Play sound for notifications.
  4. Trello keeps showing banners and badges — just no audio.
macOS System Settings → Notifications → Trello
System Settings → Notifications → Trello → toggle off Play sound for notifications.

How Chirpy fills the gap

With Chirpy you can give Trello's notifications a sound that matches their importance. For example: a quiet chime for routine updates, a louder bell for mentions, silence for the rest. All triggered by keywords in the notification text — no plugin, no API access required.

Want sounds that actually mean something?

Chirpy adds rule-based custom sounds on top of macOS notifications. One sound for Trello mentions, another for your calendar, silence for the rest.
