How can I fix iCal that is jammed/frozen/nonresponsive after trying to past in a calendar entry. I've restarted program and computer. Unable to remove entry and associated message "the server responded with an error" ICal stuck updating. Help?

I can't find this folder - library / calendar?

I go to the finder go menu and there is no OPTIONS under that menu item... I don't know what to do. My calendar is locked and I"ve rebooted, forced quit, etc.. HELP!!

Ialamc69,

What system are you using?

I have a macbook air, OS X version 10.8.4. I'm not sure where to find this file with all the caches I'm supposed to delete. And I am a former PC user and not very tech savy so maybe if you can give me very layman term instructions please?:) Thank you in advance for all the help!!!

Ialamc69,

Paste this text ~/Library into the Finder>Go>Go to Folder...window and select "Go." This will open the users Library Folder.

Then open the Calendars Folder and move any any files with "Cache" listed in the name field to your Desktop.

THANK YOU SOOOOOOO MUCH! Totally worked! Was working on this all night and you fixed in 2 min! Do I just delete the files now?

alamc69,

Glad to help...you can safely delete the files on your desktop.

Thank you so much for posting this! Worked perfectly!

You are welcome...glad to hear that advice helped.

HI, well i have the same issue and read through this helpful thread, but when I followed the steps, it deleted ALL my entries in my calendar (including holidays). Specifically, I removed all files (non-folders) from the Lbrary that had the word "cache" anywhere in the file name--I'd say there was about 30 of them or so. What's I'd like to do is get all the calendar events back EXCEPT the offending one (a copy and paste that caused the error massage). Any sugestions? Thanks in Advance.

WM. stop! Don't connect any other device to Internet. Your duplicate calendar on your iPhone or iPad has your calendar. Don't open it. Or your action will wipe it. Once you have the data safe, back on your iCal situation, when it all reloads it may be no more problem. Yet you can likely tap the message near the beginning and erase a few sentences. Keep erasing a few sentences at a time until it's gone. Or short enough to not extend beyond the boundary of the bottom of the screen. And in future don't make huge notes in calendar.

OK, thanks. I have turned off my WiFi on my iPhone (and checked that does still have the calendar entries). When I open iCal on my Macbook, I no longer get the effor message -- but, as mentioned above, I've also lost my calendr entries. Any suggestion. Is there some way to have the iPhone calendar overwrite iCal on my Mac?

And yes, i've learned my lesson about copying and pasting calendar entries with long nessages!:)

I'm not certain. At least you have them all. If have 3 devices, make a new entry in one of the non-Mac ones. And see if the Mac shuffles up all the old ones. Beyond that I would call apple. Or Genius Bar. Or macrumors chat forums. Maybe backing up iPhone or iPad will update Mac. Do phone or iPad first. Then cancel wifi and see what happens when turn on Mac. My guess. Note your important stuff!!!

I am having this issue, too. Following Ferd's advice wipes me completely out, and.. for whatever reason, I cannot restart and resync the calendars I once had, they won't work suddenly. I have to keep my cached files and somehow find a way to X out of this error window without removing my cache. Can anyone assist me?

(Couldn't edit my original post for some reason)

Since my entry that was too large came from Reminders, once I located it in Reminders and deleted it, and hit Force Quit to get out of both and restarted both, my error was gone. WHEW.

I love you, Ferd II. I'd prefer a DIY fix to a trip to the genius bar. Deleting the iCal cached files worked for me. Thanks for the gift of information and time.

OK, so "love" might bit overstating this. I really like you for providing help to us.

Thanks very much!
