I use iCloud to sync my calendar between my iPhone (6.0) and MacBook Air(OS X 10.8.2).

- My iPhone is syncing perfect with iCloud.

- Looking in every is also good.

- But not everything is downloaded in my calendar (ver 6.0), also changes on my Mac are not uploaded to my iCloud.


Problem analyse:

- There is a error symbol next to the iCloud name on the left side in calendar. It states: "request (CalDAVAccountRefreshQueueableOperation) for 'iCloud' has failed"

- My girlfriend has a different apple id but is experiencing the same problems (different account on same Mac)

- It's only calendar and tasks, contacts and mail are working properly

- When i look in the error log i see the following (error in 21h00 is the actual error, but maybe the previous is telling something)

First steps:

- Contacted apple support, spoke to 2 people. Last person told me he'll call me back but didn't

- Made a new "test" account on the macbook. Configured in "mail, agenda's and contacts" a iCloud account with my own apple id. Same problems as above



Who has an idea the next things to test? It's driving me crazy

MacBook Air, iOS 6

    Hi Karel, I had the same issue, I tried a few things like rebooting etc..none of that worked.


    I finally went into preferences of my Calendar , selected @Accounts and created another icloud account. Once that is done you will find that your calender events are all duplicated, then all you have to is delete the account that is no longer syncing.( the one with the older "Last sync date".) a few seconds later the calendar on my Mac updated with the new events that I had added since the sync problem.  Hope this works for you too.


    I have icloud on all my devices; ipad 3, iphone 4S, the new ipod Touch and of course my macbook pro. They are all upto date now...

    Good luck

    I forgot to mention when you are creating the new account, make sure you are using the same icloud name and password.

  • Karel2H Level 1 Level 1

    Thanks for the test. I performed it but also the second iCloud that I made under @accounts has te same issue's. Think it's simular as creating an new account on the mac and install iCloud.


    I do use the same AppleID for all tests.

    Seems this is happening to more than a few users. I really had gotten used to (dependent) on iCloud to keep me organized. This a big dissapointment, that it is not working how it is supposed to, for the last few days for apparently more than a few users.

    same here. software is updated. iphone syncs perfect with icloud. but in mac calender i miss two of four calenders (all entries are not available on mac)

    reboot mac, delete cache, restart icloud account on mac – nothing solved this problem!

    same problem for me. iMac / iPhone ok, but on my macbook I'm not able to display all events of my iCloud account. On all events exists

    "request (CalDAVAccountRefreshQueueableOperation) for 'iCloud' has failed"


    Same problem for me too, although interestingly I have 2 iCloud accounts and it is only affecting one of them.


    I even loaded my iCloud account onto my partners Macbook Air and I encountered the same problem with my calendar (her calendar was fine). iPhone + = totally up to date. Macbook Pro only receives old events and does not send anything.

  • Mr Morgan Level 1 Level 1

    After much fiddling with my Calendar I have resolved the problem:


    1. I exported all the calendars individually and saved them on your desktop


    2. Using an iOS device delete all the calendars on your iCloud account (you should be able to use in the same way)


    3. Now that your iCloud calendar is empty, import the calendars from your desktop one by one waiting for them to fully sync before doing the next one.


    4. Done!


    *I discoverd that one of my calendars was corrupted and would not install, perhaps this was the problem? However I believe that it was because my calendars had too much content (multiple repeating events and sporting event subscriptions). I got rid of the sports ones (huge) it was very slow to upload, and I decided to slim that calendar down as it's not very important.


    I personally think it's a calendar event overload problem, too much content for iCloud to handle. It would make sence because I had no problems with any other part of iCloud (reminders/notes...) and my iPhone calendar was fine (because it does not upload any old events, ie dramatically less content)  I hope this helps!

    Amazing, this solved my problem. Thanks a lot!


    It seem that making calendar level changes - such as creating new calendars or changing names of existing ones - on the Mac does not work correctly with syncing. After creating a new calendar on, exporting and deleting the old one and importing the events from my old calendar on my mac everything is working fine now.

  • rwissmann Level 1 Level 1

    Turns out it only solved the problem temporarily. I am back to seeing the same error message as before.

  • melaniebruner Level 1 Level 1

    I too have a MacBook with the same error message and have tried many things with no fix.

 , iPad and iPhone all working together just fine.  The Mac is the odd man out. 


    Very frustrating.

    UPDATE on my own initial problem statment:

    I'm in contact with apple support and performed the following:

    - Make a backup and perform a clean install. (I made a backup before)

    - Didn't restore backup and activated iCloud. Same issue accurs

    - Apple advisor activated my iCloud on his PC. Same problem.

    Conclusion: I looks like that it hasn't got anything to do with my PC, but with iCloud itself.


    So problem hasn't been resolved. The apple advisor transferd the problem to a iCloud department. I'm waiting for the answer but that will probably take a week. Keep you posted.

    It is not possible to create a new account with the same name as an existing account!!!
