“Since I couldn’t find a way to make Finder show the hidden directories”

Use ‘command-shift-g’ to force the Finder to display any directory to which you have permission to view. If you pause while typing in the “go to folder” dialog box, it will attempt to auto-complete the directory name. So, “/A” should auto-complete to /Applications.

If you wish to show all file system invisibles, enter in the Terminal:

defaults write com.apple.finder ShowAllFiles TRUE

Restart the Finder whichever way you prefer to see the change.

Thanks for the Funambol info.
