how to make cron wake my Mac?

Is there any way to get cron to 'wake' the machine or do I have to turn off the power save mode altogether?

Hi

I have been confused for a while now about why my cron jobs don't always run. I think I now understand that cron does not run when the machine goes into power save after I have left it for 20 mins.

Is there any way to get cron to 'wake' the machine or do I have to turn off the power save mode altogether?

I would look at the Energy Saver system preference to arrange for the Mac to be woken up on a particular schedule, and then get your cron jobs to run just afterwards. Or use the pmset(1) command instead of Energy Saver.

In System Prefs, Energy Saver there's an unobtrusive button labelled Schedule... that you can use to trigger a wakeup a couple of minutes before your cron jobs fire.

Thanks, pmset was exactly what I was after.

While we're talking cron, is there a cron job editor better than Cronnix (which seems to live up to its name)? I know it's not cool using a special app, I should be using vim or something but life is too short (although not too short for writing cron jobs)
