Since I installed Mavericks and since Apple obliges us to now sync through iCloud (as if all the planet had 100% secure and fast internet), I am stuck with iCal that keeps "Moving calendars to server" and ends up in "Server responded 400 to the operation calDAVMigrateToServerQueueableOperation". Any on how to get out of this trap ? I tried to back up my calendars, erase them from iCal, erase them from iCloud, disconnet the accounts then reconnect, I am still stuck.
Help guys thank you (and many thanks to Cupertino, this is probably my last post before shifting - an Apple fan since 1981)
