Description
Unified Calendar Sync is a lightweight macOS menu bar app that creates and maintains a dedicated unified calendar acting as your single source of truth.
The app syncs events from multiple calendar accounts into a user-selected target calendar, keeping events updated over time and preventing duplicates.
Because events are written into a standard calendar chosen by the user, such as iCloud, synced events remain visible wherever that calendar is accessible.
It works seamlessly with the calendars already configured on your Mac, including iCloud, Exchange, CalDAV, and subscribed calendars, with all processing done locally.
