Hi.
Well, there is some progress. I decided to leave launchAgents and launchDeamons behind me and tried it the Jamf way.
The idea is:
- a ongoing Jamf policy which starts a script with recurring checkin
- it checks if the idle time is over max and if a user is logged in
- is no user logged in and the max idle is hit -> shutdown without user interaction
- if there is a user and the max idle is hit -> show a jamfHelper with an timeout where the user can cancel the shutdown process
- if there is no user interaction with the dialog -> shutdown if the countdown is 0
My first tests seems to work. But: there is a drawback!
If the user locked the Mac and leaves for some time, he is still logged on and the dialog will not be visible in the lock .. but functional. So it will shutdown ... not good. For this particular scenario I'm still searching a solution.
here is my script so far. (some parts are also shameless stolen, but I didn't find the authors --- shame on me)
Hope this helps.
#!/bin/bash
jamfHelper="/Library/Application Support/JAMF/bin/jamfHelper.app/Contents/MacOS/jamfHelper"
idleTimeCurrent=$(/usr/sbin/ioreg -c IOHIDSystem | /usr/bin/awk '/HIDIdleTime/ {print int($NF/1000000000); exit}')
userList=`/usr/bin/w | grep console | awk '{print $1}'`
action="shutdown -h now"
#action="$jamfHelper -windowType utility -heading 'Fahre runter!' -button1 'OK'"
#cancel="$jamfHelper -windowType utility -heading 'Abgebrochen' -button1 'OK'"
#Set "Window Type" Note: Your choices include utility, hud or fs
windowType="utility"
#Set to "Logo". Note: This can be BASE64, a Local File or a URL. If a URL the file needs to curl down prior to jamfHelper
icon="/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/AlertStopIcon.icns"
# This script will call the jamfHelper to prompt a user to shutdown their computer if idle. The Parameters will be set in the Policy.
#Set Parameter 4 to "Idle Time". Note: Sets the Time in Minutes before the Window goes up
IDLE_M="$4"
# convert to seconds
idleTime=$(($IDLE_M * 60))
#Set Parameter 5 to "Timeout" - Note: Sets the timeout of the script (seconds)
TIMEOUT_M="$5"
# convert to seconds
timeout=$(($TIMEOUT_M * 60))
#Set Parameter 6 to "Window Title"
title="$6"
#Set Parameter 7 to "Window Heading"
heading=$7
#Set Parameter 10 to "Button2"
#Note: Double digit Parameters should be enclosed with {}
button2="$8"
# This will set a variable for the jamfHelper
