Enable the menu-bar icon
- Open Settings → General.
- Turn on Icon in Menu Bar.
- Choose its display and theme. Premium access also provides upcoming-event text beside supported icon styles.
Choose what the agenda shows
The menu-bar agenda uses the accounts and calendars selected for GCal’s native agenda. Connect sources in Settings → Accounts, choose calendars in Settings → Calendar, and choose task lists in Settings → Tasks. Meeting-only and Focus settings can narrow what appears.
Choose the click behavior
Under Open Menu / Open Window in General settings, choose which click opens the agenda and which opens the main window. Clicking the same mouse button again closes the open menu. You can always dismiss it by clicking elsewhere.
If the menu is empty or outdated
Compare it with the selected calendars in Settings and check whether a Focus filter or meeting-only option is active. Choose View → Refresh Calendars for a change made outside GCal. If several native surfaces are missing the same event, follow the missing-calendar checklist.
