iCal keeps deleting my calendars!
Very frequently, iCal deletes my calendars and all scheduled events. I have back up copies and every time this happens I import them into iCal but this shouldn't be the norm! Any ideas?
I was having same problem and went to see Apple Genius in February. Apple iCal and Google Calendars no longer support each other so that is why you are having issues with syncing, disappearing calendars, events. etc.
