Programmatically shut down or sleep sandboxed application Mac - macos

Question

I am trying to make an application for the Mac App Store that will shut down/sleep the Mac after a user-set time. I have tried to use AppleScript, but that won't work if I am going to use it in Sandbox mode, I have tried to Google for a solution, but I cant seem to figure it out.
Hope someone can give me a hint or link to relevant documentation.
edit: made it more precise to what I desire to accomplish.

Answer 1

There is no way to do this. You may try to get a temporary-exception to run "shutdown" or "halt" thru BSD-layer but I doubt that such an app will pass the App Store review as these are tasks that require superuser / admin rights.

Answer 2

I wrote a script once. But I don't know whether it still works. Maybe it gives you at least a clue. Sleep still works - shutdown maybe causes problems if programs are blocking the shutdown.
(Not the prettiest code but it worked for me.)

then

done
if [ $option -eq 1 ]
then
echo "Going to sleep..."
sleep 1
osascript -e 'tell application "System Events" to sleep'
elif [ $option -eq 0 ];
then
echo "Shutting down..."
sleep 1
osascript -e 'tell application "System Events" to shut down'
else
echo "No valid command found... doing nothing!"
fi
I also had to add this in my '/etc/sudoers' file (CAUTION, if you don't know how to handle this file! -> google):
# Custom privilege
