Why do I see two BusyCal widgets in the macOS widget picker?
If the macOS widget picker (Edit Widgets…) lists two BusyCal entries, it is almost always because macOS is configured to show iPhone widgets on your Mac. One entry is the native BusyCal macOS widget; the other is the BusyCal iOS widget being mirrored from a nearby iPhone that is signed in to the same Apple ID.
Starting with macOS Sonoma, the system can surface widgets from iOS apps installed on a connected iPhone — even when those apps also exist on the Mac. Because BusyCal is available on both macOS and iOS, the widget gallery ends up listing both versions side by side, which looks like a duplicate.
Fix: turn off iPhone widgets on the Mac
- Open System Settings > Desktop & Dock.
- Scroll down to the Widgets section.
- Turn off Use iPhone widgets.
- Re-open the widget picker. Only the native macOS BusyCal widget should remain.
Apple documents this setting here.
If you prefer to keep iPhone widgets enabled on the Mac, both BusyCal entries are legitimate — the macOS widget renders instantly on your Mac, while the iOS widget mirrors your iPhone's home-screen widget over Continuity. In that case you can simply pick whichever version you want to place on the desktop or in Notification Center.
