title: macOS: Change default app for files with no extension
body: <p>I want to change the default app for files with no extension from TextEdit to BBEdit.
  Cannot seem to find a correct answer to this.
  Using 'Change All' on a file's Info tab brings up an error ('not enough information available').
  'defaults write com.apple.LaunchServices LSHandlers ...' does not work.
  Spotlight and Finder search did not help.</p>
  
  <p>So where is the magic marker that tells macOS to use TextEdit ?</p>
