I can't see Warashi in the menu bar
A crowded menu bar can hide items behind the notch. Quit an app or two you don't need in the menu bar, or hold ⌘ and drag the Warashi item further right. You can also open Warashi from Applications at any time: it opens its window.
The island covers something on my external display
Turn it off in Settings › Notch › Island on other displays.
Some numbers say “unavailable”
Warashi never invents a value. If macOS doesn't offer a reading on your Mac (for example temperatures on some models), it says so instead of guessing.
System processes aren't shown
They need the optional helper: see System processes. If you turned it on, check System Settings › General › Login Items › Allow in the Background.
Open at login doesn't stick
macOS may need your approval in System Settings › General › Login Items. Warashi shows a button that takes you there.
Still stuck?
Email adam@warashi.app with your Mac model and macOS version.
