Can't Delete Events or Calendars

Here's what I just did that seems to have worked. (Finally! I've been having this problem forever!)

First I ran the sudo command in Terminal from this thread. Afterwards, I wasn't able to simply delete the event in question the way I can with newer events.

The event in question was a recurring event, so I opened it, then using the pulldown menus, changed it from a recurring event to a non-recurring event. It took two times for iCal to accept the change, but once it did -- YEA!! -- the lil' stinker was deleted.

Hope this helps.

I tried your suggestion, as well as all the others on this post. It seemed to work, initially, but it keeps coming back! I have to go forward every week to manually change to a non-recurring event, and sometimes it does take 2 tries, and it seems to work, but when I go back a week, it's come back. I tried the sudo and deleting the cache as well. Any other suggestions?

Deleting the Calendar Cache file worked for me.

Thanks for the tip.

Neither the sudo option or the Cache option work for me. My events still cannot be deleted! It's driving me mad!

This is clearly a bug in iCal that Apple will have to provide a fix for very soon. Neither of the suggested solutions work for me either, and my calender is rendered pretty much useless.

Deleting cache worked. Make sure to close and open iCal after deletion.

For me, these methods did not work. At first I could delete the bad events and then they magically returned! This is what I did:

1. Close iCal
2. remove ~/Library/Calendars/Calendar Cache
3. sudo chmod -a# 0 ~/Library/Preferences/
4. Started iCal -- it says, "upgrading iCal calendars"
5. I remove the bad events
6. The offending events appear

The rest of the calendar appears to be working.

I understand that this is an Apple issue that they should be currently working on. However, we, the users, need to know:

QUESTION: should I shut down iCal until this is fixed (e.g., iCal will corrupt more of its data as it runs) or can I safely continue to use it?

I don't see how this question can be marked "solved," when so many posters said that the answers did not help. I will re-post the question in a new topic, so that it remains open for further input.

I've found that changing the permissions of your home folder to allow "everyone" to read and write solves this issue. I'm sure applying it to an iCal-specific preference folder would work just as well.

After playing around with iCal to confirm this fix I reverted my home folder permissions to "everyone" read-only. Yet to my surprise, iCal is still fixed!

(P.S.: remember to apply to enclosing folders)

This did not fix the problem for me. I still have several events that I cannot delete.

Thanks though,

The following worked for me, to remove the iCal events that were "stuck."
This removes all of the iCal data, including the corrupted stuff, and replaces it with uncorrupted data from your iTouch/iPhone.

This assumes that you have an iTouch/iPhone which has your calendar events.

1. Backup: Launch iCal and select File > Backup iCal and save the
file. Might as well backup Address Book and Mail as well.

2. Delete: Quit iCal and all open applications then delete the
following folders:

∼/Library/Application Support/iCal
∼/Library/Application Support/iSync
∼/Library/Application Support/SyncServices
∼/Library/Calendars

Note: The "~" character above is shorthand for your Home directory.

3. Logout and Login, or restart your computer.

4. Launch iCal. It should be blank.

5. Restore: Plug in your iTouch/Phone, set iTunes to sync iCal with iTouch/iPhone, and then press the iTunes button to sync iTouch.

No, that is not the way to remove the SyncServices database from the computer. Apple strongly recommends against that. The way to do it is to follow these instructions:
