MacBook Pro mid-2015; MacOS X 10.11.6:
Recently my special calendars (Birthdays, Canadian Holidays) have failed to show on my Apple Calendar app. And yet they show fine on my iPhone. The calendars are switched on in Calendar preferences. What else might be wrong?
Thanks.
MacBook Pro with Retina display, OS X El Capitan (10.11.1), 16GB RAM
