Can't open files after upgrading to Mavericks 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!
Maybe you could start by moving ~/Library/Preferences/com.apple.finder.plist (where ~ is you're home folder) to the desktop and restart the Finder by typing sudo killall Finder into terminal. If it works with another user, it may be something in you're Library folder that is causing the problem. I would also check you're startup items under System Preferences:Users:Login Items. Another thing that could help is check you're logs in the Console Application and see if it is reporting anything unusual there.
