After upgrading from ML to Mavericks (MB Air, 13", 256GB, 2011) I can't open any file or folder from the standard Open menu from any app (except MS Office -2011). But, I can search for a file (and open it) if it has a label. All the files/folders are greyed out so can't select them, as it can be seen in the attached screen capture (from Preview.app).
If I try to save a file, the only place I can do that is in the default folder: if I try to change the folder (navigating through the Save box) I can't save it any more.
What I've done (nothing worked!):
- repairing permissions
- delete and create a new user (keeping the user folder in /Users)
- updated to 10.9.1
It is worth to point out that this only happens in my user account: after discovering this situation I created a second admin user and everything works fine within it!
