When something is wrong

No icon in the menu bar

A menu bar with no free slot left of the notch drops the icon: macOS draws no status item it cannot fit, and nothing in the app can claim the space. Free a slot, or open the app again from Finder or Spotlight — a second launch opens Settings instead of a second copy.

The icon says macOS is withholding key presses

An old entry for the app is denying it in System Settings → Privacy & Security → Input Monitoring. Remove that entry with − — the app does not need the permission, only the absence of a refusal — and click back into the app; the tap is rebuilt without a relaunch.

⌘Tab is still the system switcher

The Accessibility grant is missing or belongs to the previous build. Use Grant Accessibility… from the menu bar icon, and if the list already has an entry for the app, remove it with − and grant it again.

”Open at login” does not stick

If macOS refuses the registration it says so under the checkbox, in its own words. The usual reason is a build the system does not recognise: every local build carries its own ad-hoc signature, so a registration made by yesterday’s copy does not belong to today’s. Turn it off and on again on the copy that is in /Applications.

Reporting a bug

Copy Inventory in the menu bar copies the current Space’s application list to the clipboard — that is what to attach to a bug report.
