After unhiding files via terminal command, hiding command does not work. It seems that system doing something (Finder restarts), but hidden files and folders still there. Also neither work special apps for that (Funter, Show-Hide Invisible, etc.). I am using Xtra Finder. Uninstalled it, because thought that it can cause problem. But even after uninstalling same problem... MacBook Pro Retina. OS X Mavericks.
