Q: How do I clear the iCal or Calendar cache in OS X?

Answer

Note: Make sure to create backup copies of each of these files before deleting them.

Some iCal and Calendar issues may be resolved by removing the calendaring account(s), quitting and restarting the application, then re-adding the account(s). It may also be useful to clear the iCal or Calendar cache and delete the application's preference files.

If you are using OS X 10.7 and up, your user account's Library folder is hidden. Please use one of the techniques listed on this page in order to access the Library folder.
  1. Quit iCal/Calendar.
  2. Make backup copies of these files before deleting them.
  3. Delete the calendar cache found here:
    ~/Library/Calendars/Calendar Cache
    ~/Library/Caches/com.apple.iCal (if these files exist)

If there are additional issues, the following may also be useful:

  1. Quit iCal/Calendar.
  2. Make backup copies of these files before deleting them.
  3. Delete the Events directory found here:
    ~/Library/Calendars/*.calendar/Events
  4. Delete the application's preference files here:
    ~/Library/Preferences/com.apple.iCal.plist
    ~/Library/Preferences/com.apple.iCal.helper.plist (if this file exists)
