Is there a way to push a lock screen message through Casper? (System Preferences - General - Show a message when screen is locked). As per support there is no configuration profile payload that can be used. Also found this command doing a google search: sudo write /Library/Preferences/com.apple.loginwindow LoginwindowText "Your Message Here", but that does not seem to do the trick either. Machines are running a mix of 10.11 and 10.12
