This hint works great for me, a 'Terminal-fobic':
- Place the Pseudo application icon in the Dock
- Run TransparentDock and select 'Place "Quit" menu item in Finder Dock Menu'
- Quit Finder from its new dock menu
- In Pseudo, select Launch from File menu
- Go to /System -> Library -> CoreServices -> Finder.app and doubleclick
- Quit Finder again from the dock menu
- Click the Finder dock icon to start Finder again (now as your own user) and everything is back to normal.
