I have a rather odd problem with my mac... None of my 4 Google calendars (2 gsuite, 2 normal) sync properly after around 5PM. The Calendar UI only shows The server responded with an error.
- Clearing the calendar app cache following this procedure
- Removing and re-adding these accounts entirely
- Entirely removing ~/Library/Caches
- NVRAM and SMC reset
- Upgrading the entire system from Catalina to Mojave
The only clue I have is this line from logs is:
CoreDAVPropFindTask failed: Error Domain=CoreDAVHTTPStatusErrorDomain Code=403 "(null)"
But still no love. Does anyone have any ideas? This is one of the more bizarre computer problems I've ever had.
