I have some macros I leave running and walk away from; if the computer falls asleep while the macro is running it prevents me from typing in my password to wake. 
I’ve tried to figure out how to do this myself for a few days and can’t find a good way to do it. How do I set a group of actions to loop for X seconds instead of X repetitions, and/or how do I cancel a macro after X seconds?
Thank you
Hi
If I need to make sure my computer stays awake while running a macro I use this program

It prevents the computer from going to sleep.
This is a great alternative. I will keep it in my back pocket, but I would still like to learn if there is a way to do the cancellation or exit loop by time. Thank you!
You could have a macro triggered by Sleep with action Cancel All Macros.
Otherwise, to loop for N seconds, do something like:
