# This script uses AppleScript to prompt for a hostname, then sets it on the computer.
# Recommended: a recon at the end of the QuickAdd enrollment workflow to make sure the JSS
# shows the correct username.
#
# Provided as-is without support or warranty. 
# Please test and verify before deploying in production.
