One of the things missing from OS X is the ability to ctrl+click a file and copy it’s full path to the clipboard. It amazes me that this feature is missing from such a robust OS. This tip should make your life easier. You can see the full path in the title bar when you select a file in the Finder.
1) Open a Terminal window and type this command:
defaults write com.apple.finder _FXShowPosixPathInTitle TRUE
Of course replacing
FALSE will turn this feature off.
2) Restart the Finder:
Cmd+Option click the Finder in the Dock and select "Relaunch"
Note this works from User accounts as well as Admin accounts. No need to “sudo” from within the User account.
