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. |
- Quit iCal/Calendar.
- Make backup copies of these files before deleting them.
- 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:
- Quit iCal/Calendar.
- Make backup copies of these files before deleting them.
- Delete the Events directory found here:
~/Library/Calendars/*.calendar/Events - Delete the application's preference files here:
~/Library/Preferences/com.apple.iCal.plist
~/Library/Preferences/com.apple.iCal.helper.plist (if this file exists)
For Yosemite users, this Apple support thread might be helpful in debugging your issues if none of the above work.
