This is on my Wife's Intel MBA with Ventura 13.2.1. She had a problem importing an ics file from an online source that works fine on my MBP.
Upon closer investigation her Calendar (iCloud) was completely empty of events and if I tried to add the event from the ics file I got an odd error message:
Investigating further it seems that if I try to add an event to the calendar, nothing happens, literally. Selecting File → New Event or clicking on the "+" button there is no response from calendar.app.
Then I notice (duh) that there are no calendars listed in the sidebar, So I try File → New Calendar and get this:
Now I go into Calendar's Accounts Preference pane and remove and then try and re add her iCloud calendar (there are two Gmail accounts there but they are disabled there, and calendars are turned off in those accounts in System Settings) but when I try and log in it says her iCloud account is locked for security reasons... Grrr...
I log into her iCloud account, reset the account password and try again. Having verified that calendars are turned on in System Settings → iCloud and that her calendar app is working just fine on her iPhone, none of her calendars show up in the sidebar (and I still can't add an event). Which makes some kind of sense as there are no actual calendars to display besides the default calendar that is displayed when there aren't any calendars.
There was one lone Calendar.app preference file in the
~/Library/Preferences folder which I deleted with no detectable change in behavior and I did not find any other preference/settings files anywhere else in
I am a loss as to why the calendars that display fine on my wife's iPhone are MIA on her MBA
