Common questions
How do I open Plateau?
Move the pointer to the top center of the screen, onto the notch, and the island opens. Move away and it closes. On a Mac without a notch, Plateau shows a slim pill at the top center instead. You can also click it, or set a keyboard shortcut in Settings › Notch Hub.
Where are Plateau's settings?
Plateau lives in the menu bar and has no Dock icon. Click its menu bar item (the battery percentage), then the … button › Open Plateau. The gear in the open island opens the same window.
Now Playing doesn't show my music
The first time Plateau reads Music, Spotify, TV or VLC, macOS asks for permission. If you declined, open System Settings › Privacy & Security › Automation and turn Plateau on for that app. Plateau only reads players that are already running, and you can choose which ones in Settings › Notch Hub › Players.
My calendar events are missing
Allow calendar access in System Settings › Privacy & Security › Calendars. Plateau shows events from the calendars you have in the Calendar app, today only.
The weather is for the wrong place
Plateau doesn't use your location. Set your city in Settings › Weather and it will show the forecast for that city.
Does the timer keep running if I close the island?
Yes. The time stays visible in the closed notch, and a running countdown even survives quitting and reopening Plateau. When it ends, Plateau chimes and opens on the timer.
How do I remove Plateau completely?
Quit it from the menu bar, then drag Plateau from Applications to the Trash. Its notes, clipboard history and settings are stored only on your Mac, in Plateau's app container, and are removed along with it.
