(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:
- Backup your computer Addressbook: http://docs.info.apple.com/article.html?path=AddressBook/4.0/en/ad961.html
- Backup your computer iCal: http://support.apple.com/kb/HT2966
- SafeBoot your computer: http://support.apple.com/kb/HT1455
- That will disable syncing temporarily so that the sync database is not in use when you modify it.
Restart the computer when you are done to take yourself out of SafeBoot.
