Hey guys,


I recently purchased a late-2011 13" MBP and upgraded it to ML.  I did not have any prior issues with my iPhone/Mac/iPad/Black MacBook syncing together with iCloud, which is why I'm perplexed after countless Google searches and resets with no answers.  My iOS devices are still syncing properly.  I can access my updated calendar at iCloud.com.  Everything works except for iCal on Mac with iCloud.  I now have an exclamation point next to iCloud in the calendar along with a phantom Google calendar that is no longer shared.  The error message I get is:


The server responded with an error.

The request (CalDAVAccountRefreshQueueableOperation) for account “iCloud” failed.


Does anyone have a solution for this?  I've attempted signing in and out with different accounts to test, allocate and/or delete files from the Library > Calendar folder, Preferences folder and SyncServices, and also verified disk permissions.  I'm re-downloading ML now to try re-installing it.  I'm out of ideas.

MacBook Pro, OS X Mountain Lion (10.8.2)

    Hey folks I found a workaround.  I created another calendar within my iCloud account and migrated everything over to the new account.  I guess the old calendar name became corrupted in the midst of the upgrades and device changes.  Either way I'm back in business!  Hope this helps.

    I have the exact problem. Glad to hear you found the workaround. I've been using iCal for a long time and haven't the foggiest how to migrate everything over to the new calendar (or is it a new account? I'm unclear). I think I can figure out how to create a new calendar.

    Hey there!


    I apologize for my terminology because it probably wasn't accurate or that clear. 


    While using your existing Apple ID or iCloud account, open Calendar, then go to File > New Calendar > iCloud.  Give it a different name and color than your existing calendar for troubleshooting purposes(you can always delete the old one and rename it and change the colors later).  Once the new calendar is created, try creating a new event under it to make sure that it syncs across all of your devices.  In my scenario, doing this revealed that the new calendar synced correctly while the old one continued to show an error icon.


    As far as migrating the calendars, I think there are two options.  Luckily for me I didn't have too many events so I went into each event and edited them at the bottom where it indicates which calendar you want to associate the event with.  The other method that I was going to try, but wasn't sure if a corrupted event/setting would carry over to the new calendar if I did, was to export my old calendar to my desktop, then import it back into my new calendar.  Theoretically, this should move all of those previously entered events under your new calendar without having to click into each event like I did.  Because I've never tried it, I can't speak to whether or not the original error would return.  *However, if your Mac Calendar is empty due to syncing issues, the export method won't be of much help as it only exports what is currently visible in that calendar.  But if your calendar currently contains all the events you'd like to keep, but it just can't sync anymore, then exporting and importing might work.


    If you decide to try the export/import method, it's pretty straightforward.  After you create the new calendar, click on the old one and go to File > Export.  Save the file to your desktop, then go to File > Import.  Choose the file you just saved and select the destination as the NEW calendar you just created.  Again, theoretically, it should work.


    Good luck!

    I followed your clear instructions and it fixed half the problem. I was happy for that. It eventually worked out, as I reported in a separate discussion. Thanks!
