User Idle Time Timer Script Not Working Any More with M2

[sgiesbrecht]

Hello everyone

Need assistance with users idle time.

When I run the following script on my workstation ( Apple M1 Backbook Pro ) I get what I need but when I run on a M2 Mac mini, it does not work.

After moving the mouse or pressing a key, the counter just keep increasing.  It looks like the IOHIDSystem is using the computer logged in time.  

I am wondering is there a new way to check for user idle time, command or in Jamf Pro itself.

See the out below.

#!/bin/zsh

# Pause/Interval between checks
checkInt=1

# Timer in sec
timerLength=15

# Keep track of the idle timer
lastIdle=0

# Get the current user
current_user=$(who | awk '/console/{print $1}')

# Get the computer name 
computer_name=$(hostname | sed 's/.local//')

# Message to system.log
log_message="User $current_user Test"

# Function
while true ; do
	ioresp=`ioreg -w 0 -c IOHIDSystem | sed -e '/HIDIdleTime/ !{ d' -e 't' -e '}' -e 's/.* = //g' -e 'q'`
	idleNow=`echo $(( ${ioresp} / 1000000000 ))`

	# Get the current date and time
	current_datetime=$(date "+%Y-%m-%d %H:%M:%S")

	re='^[0-9]+$'
	if ! [[ $idleNow =~ $re ]] ; then
		echo "error: ioreg did not return a number" >&2; exit 1
	fi
	
	echo "Idle now is $idleNow secs"
	
	# if idle decreased then action occurred so we do something...
	if [ $idleNow -ge $timerLength ] ; then
		echo "$log_message at $current_datetime"
		exit 0
	fi
	
	sleep $checkInt
done
