Welcome to the MacNN Forums.

Does anyone know of a simple way to run an apple script every 60 seconds? I understand the "return 60" but that does not appear to work for me. Is there a small program I can run that will execute apple script every 60 seconds?

Is your code in the onidle method and not the run method?

There is something built into the system called 'cron' that is designed to run things periodically.

You can edit the "crontab" which sets it up by hand in the terminal but it is pretty arcane.
type: man 5 crontab for system help

here is an intro:

OR

Here is a simple gui interface to it:
