FaceTime shows persistent notification badge on macOS with no unread calls

I had the same issue on my iMac. I was able to get rid of it by removing icon from Mac Dock

• Right-click the icon
• Options
• Remove from Dock

Then add it back to Mac Dock

• Open FaceTime
• Right-click its icon in the Dock
• Options
• Keep in Dock

^ same here. Will try removing the FT icon from the bar and reinstalling.

EDIT: yeah, that worked. Remove FT icon and re-add. Simple but frustrating.

1. Force Quit and Restart the Dock

This is the least invasive method and often resolves minor glitches.

1. Open Activity Monitor (located in /Applications/Utilities).
2. Search for ‘Dock.’
3. Select the ‘Dock’ process.
4. Click the ‘X’ button in the toolbar (or press Command-Option-Shift-Esc) to force quit the process.
5. macOS will automatically restart the Dock.

Restart the Dock and Notification services (MOST EFFECTIVE)

This resets the badge counter.

How?

Neither handlings of force quitting Dock and Notification services worked for me. My iPhone FaceTime app doesn't show the missed call notification. Just on my Mac - with Tahoe 26.3.
