iCloud's function "Documents & Data" is not available for my main user in all applications. When i use for example TextEdit i can do File -> Move To … and then select either iCloud or Recent Places or Favorites or Devices. But on my main account "Move To …" does not show the iCloud option.
Every other program for this user cannot use iCloud documents too. What might be wrong with my user?
Of course "Documents & Data" for iCloud in System Preferences is enabled.
Also when doing "Open …" with TextEdit and then clicking iCloud, the view below remains local file system and does not show my TextEdit iCloud documents like on other Macs. It cannot access iCloud obviously.
I fixed it by creating a new user and moving my data from the old to the newly created user. I used this http://support.apple.com/kb/HT1428?viewlocale=en_US&locale=en_US to do it.
Resetting permissions and ACLs in home folder via Command-R boot and then resetpassword-utility did not work well, so i used the link above which is a nice trick to get the pemissions in ~ right.
I omitted to copy in ~/Library/Application Support/ everything iCloud-related like iCloud, Librarian, SyncServices, Ubiquity. Also i did not copy ~/Library/Mobile Documents.
Finally i renamed home and recreated the original account with the link above to get my original Unix user name back.
Now iCloud is working on this account again. This account had already some other troubles like you can see in my earlier discussions. Something must have gone wrong during some upgrades - just my guess.
