macOS shortcut/bash script to immediately close (UNIX signal 9/SIGKILL) all "Not Responding" programs
Here is a Applescript I used on Maverics...

It basically looks for 'Not Responding' apps in Activity Monitor and Kills them

tell application "Activity Monitor" to run  --We need to run Activity Monitor
tell application "System Events" to tell process "Activity Monitor"
     tell radio button 1 of radio group 1 of group 1 of toolbar 1 of window 1 to click --Using the CPU View 
     tell outline 1 of scroll area 1 of window 1 -- working with the list 
         set notResponding to rows whose value of first static text contains "Not Responding" -- Looking for Not responding process
         repeat with aProcess in notResponding
             set pid to value of text field 5 of aProcess  -- For each non responding process retrieve the PID 
             if pid is not "" then do shell script ("kill -9 " &amp; pid) -- KILL the PID. 
         end repeat
     end tell
end tell
