Mac Calendar filled with duplicate entries after update to Ventura 13.4
I updated my iMac to Ventura 13.4, after which my calendar is completely screwed up. Every day looks more or less like the screen shot I included here. It has taken an entry from another day and duplicated it many times over for today's date. This same thing is repeated for every day, every week. The calendar is unusable. I restarted again but that didn't change anything. What do I do now?
