AppleScript: Quit All Applications
I often use this script with ARD to quit all open apps. Useful for when some malevolent students sets every app to open at login.
tell application "System Events" to set the visible of every process to true set white_list to {"Finder"} try tell application "Finder" set process_list to the name of every process whose visible is true end tell repeat with i from 1 to (number of items in process_list) set this_process to item i of the process_list if this_process is not in white_list then tell application this_process quit end tell end if end repeat on error tell the current application to display dialog "An error has occurred!" & return & "This script will now quit" buttons {"Quit"} default button 1 with icon 0 end try
