All calendar events disappeared from Mac. Still visible on iPhone and iCloud
All the calendar events have disappeared from my Macintosh. There are hundreds, past and future, in multiple calendars. They are all gone. They don't appear in the calendar view and they don't appear when I search for them.
The calendar events all still appear in iCloud and on my iPhone.
I have toggled the view for each calendar on and off. I have quit the Calendar app and restarted it. I have rebooted my Macintosh. All the events are still gone.
I have confirmed that my Mac is still set up to sync calendar data with iCloud.
Does anyone know a safe way to get these calendar events back onto my Mac? I have thought about turning iCloud syncing off and then on again, but I don't want to do anything that will delete the events from iCloud and my iPhone.
I am using a MacBook Pro with Mac OS 11.6.5, the latest available for this machine.
Thanks in advance.
MacBook Pro 15″, OS X 10.11
