I have an answer..
Heres a sample script:
if sRunning is empty then put false into sRunning
put not sRunning into sRunning
if sRunning then
put the last word of (shell("ioreg -c IOHIDSystem |grep Idle")) into tIdle
put tIdle / 1000000000 into field 1
send "loopit" to me in 2 sec
The script is in a button, and I have a single field on the card. The math
is done to convert to seconds of idle.
The are only 2 disclaimers here. First is that the value returned pre 10.3
is hex so you'd have to handle that if you have an earlier osx. 10.3 and
after this solution should work fine.
The second issue is is that on mac 10.12, the idle time won't update on
typing. Its an osx issue for that specific version, but worst case you
already have a method to track keypresses.
