I am having problems with a curropted database and I need to completely delete it and start over again. I think moving over to iCloud trashed my calendars. I turned off iClloud but the curropted database is still with me. I know Apples hides these things very well but someone out there surely has found it.
(user)/Library/Calendars. If you are on Lion, Apple have hidden the user’s Library folder to casual viewers, in an attempt to stop new Mac users screwing their machines up. To access it, in the Finder go to the ‘Go’ menu and hold down the Option (Alt) key; the Library folder will appear as a choice.
I found the iCal info and deleted all of it. I also went to the pref filkes and deleted all of them also. I turned off iCloud also. As soon as I opened iCal the information came back from somewhere. I also emptied all of the casches. I am not sure wnat to do next. I not only have duplicates I have information from dates that are all mixed up. I have to find a way to purge the entire database and keep it from comming back
Before removing this file:
Restart the computer when you are done to take yourself out of SafeBoot.
