    I've been using ML since launch and just noticed that I'm missing some calendar events on my 4S. Double checking and doing some testing I've figured out that events created in the in ML do not get pushed to iCloud (not visible on my 4S or on New or changed events on my 4S or do show up in however if I create, delete or modify in the change is not pushed to iCloud.

    I've also noticed that in the there it is constantly "Updating..." near the application title.

    I've gone through the iCloud Troubeshooting document with no help.

    I spoke with Apple Tech Support and they are looking into the issue.

    I took a look at the logs (not sure why I didn't do this before) and it appears that the CalendarAgent is continually crashing. I booted from a test install of ML on an external drive, no issues with iCloud & sync. Moving the CalendarAgent executable over and repairing permissions did not help, issue persists. Is there a file somwhere that this needs to be fixed? Seems like the host information has been set to nil.

    Upon seeing and reading this thread I decided to try it myself. I changed the time of 1 event and added 2 more events using Calendar on MBP.

    Within a few seconds the change and additions were showing on both my iPhone and via iCloud.

    Sounds like your problem may be isolated.

    Try resetting Sync Services

    I just upgraded to ML. I don't use iCloud and after the upgrade all of my calendars were empty. I reset the sync services by following the instructions shown here
