If something's not right
- “Warashi can't be opened” or the app is damaged: download it again from warashi.app and open the new copy. Only download Warashi from warashi.app.
- Your Mac says it isn't supported: Warashi needs Apple silicon and macOS 26. Intel Macs aren't supported.
- You can't see the spirit: a crowded menu bar can hide it behind the notch. See I can't see Warashi in the menu bar.
