So, basically some how I have buttloads of duplicate entries in the calendar in my iCloud. Now I guess i could go and manually delete all the duplicates, but that would take forever. Because they're duplicated in the cloud, they are also duplicated on my mac. So now, my first solution was to use this iCal dupe deleter and delete them. It does this well on my mac, but a second later the entries are back pushed from iCloud. So any advice here? Is there any way to have iCal replace the information in the cloud? Any way to delete the iCal data in the cloud, and then sync the local calender? Any other way? Thanks! psych EDIT: I actually managed to solve this myself, and perhaps other people have the same issue so I'll post it. Basically i took my local iCal offline, used the duplicate program to delete all the duplicates. Then I exported each of the calenders to separate files (right click each calenders - export). Remember this were all under the iCloud 'banner'. Then i proceeded to delete all of the calenders in iCloud (edit - red stopsign, delete). This of course did the same in local iCal. After this i imported each of the individual calendars to 'On my mac', disabled and re-enabled calendar icloud syncing in system preferences, and voila, the new updated iCal was pushed to the icloud, containing no duplicates.
