After upgrading to Smith Micro Software’s StuffIt 12 (either the Standard or Deluxe versions), DropStuff may no longer work properly. Instead of compressing your file when you try to use it, StuffIt Setup Assistant launches in error.
The fix is a common one: Delete the relevant preferences file. In this case, go to your user folder /Library/Preferences folder and delete the com.stuffit.DropStuff.plist file.
