We will need to modify a Finder's file, so take the usual precautions: back up your stuff! In short:
- Edit the objects.xib file, found at /System » Library » CoreServices » Finder.app » Contents » Resources » your_language.lproj » ClipWindow.nib » objects.xib.
- Change this line:
to<boolean name="noSelection">TRUE</boolean>
Then save your changes.<boolean name="noSelection">FALSE</boolean> - Restart the finder.
In detail:
- Go to this path: /System » Library » CoreServices » Finder.app » Contents » Resources. Here you will find one folder for each language that you have installed. In Terminal, change the directory to the language where you want to make the changes. I use Spanish so cd Spanish.lproj/.
- Now you have to cd to ClipWindow.nib: cd ClipWindow.nib/.
- Edit the file objects.xib (you should make a backup of this file first): sudo mate objects.xib -- I use TextMate, but you could use your favorite editor. You will need to edit the file with root privileges.
- Change this line:
to<boolean name="noSelection">TRUE</boolean>
Save your changes and quit the editor.<boolean name="noSelection">FALSE</boolean> - Press Command-Option-Escape (or use Terminal, the Finder's contextual Dock menu, or Activity Monitor) and relaunch the finder.
