Mac os clipboard

(*
  Displays some of the macOS clipboard data.

  Includes a Demonstration of how dropping files on AppleScript icon works and shows items added to folder.
  Shows how to debug via on run path.
  Save as an Application Bundle.  Don't check anything.

 It is easier to diagnose problems with debug information. I suggest adding log statements to your script to see what is going on.  Here is an example.

For testing, run in the Script Editor.
    1) Click on the Event Log tab to see the output from the log statement
    2) Click on Run
