Rain sounds on Mac. Set a quiet background.

If you only want an ambient sound, check System Settings → Accessibility → Audio → Background Sounds. The exact options depend on your macOS release. Choose a sound and set a comfortable level before deciding whether you need another app or a layered mix.

An ambient background is a personal workspace preference. It is not a guaranteed productivity treatment. Test it with the task you already intend to do, and choose silence if that works better. Keep the level low enough that it does not compete with a call, alert or nearby conversation you need to hear.

1. Open Sounds in the island.
2. Start one layer, such as Rain, Waves or Café.
3. Adjust the slider that appears for the active layer.
4. Add another layer only if useful. Use Stop All when the session ends.

The tool's ambient layers are generated on your Mac. They are separate from Spotify or Music playback, so pausing a song need not stop an active ambient layer. The header lists the sounds currently playing, which is useful if an unexpected background remains after another player is paused.

If you do not hear a layer, inspect its own slider and the Mac's selected output. If you hear too many sounds, stop the layers explicitly and check whether the built-in Background Sounds feature is also on. Running both systems can make it unclear which control owns the remaining audio.

For headphones or desk speakers, switch audio output helps distinguish routing from the mix itself. A Pomodoro can structure the work interval, but the sound layer is a separate choice. Stop it when you finish rather than assuming another timer or music player's pause button controls it.
