I like to keep Folding@Home running on my Intel iMac 24/7, but at night I would like to turn the screen off but keep the CPU going.. is there a way?

System Preferences -> Energy Savings -> Turn Off Screen After 1 Minute of Inactivity... or something like that.

^^^^^

But that would be nice if there was a screen button, like every other screen in the whole wide world.

Can't you just turn it to 0 bars in brightness? That's so much faster on the keyboard...

No, because on a notebook, turning the brightness to zero kills the backlight. On an iMac, setting the backlight to zero doesnt turn it off completely.

I find this, by far, the most annoying thing on my iMac.

He means kills in that it turns it off not as in it does damage to the backlight; i.e. kill the lights.

Oh, and the first reply is the best and, as far as I can tell, only solution to the OP's question. My CPU never sleeps but my display does after 30 minutes.

I was searching Google for the fix for a problem I'm having (when I turn the screen off, every once in a while it decides to wake up on me even when I'm not touching anything, and I don't know why - this is annoying at night), and came across this question, which I notice hasn't been answered, so I registered just to give this answer, because it's very nifty.

On every Mac, you can turn off the screen immediately with the keystroke ctrl-shift-eject. You don't need to change your sleep settings or download any apps or anything.

I hope some of the people who were asking this question see this, heh.

ZOMG! I've had my iMac for over a year now and did not know this... Like other posters this has pissed the ever loving piss out of me at night when it decides to wake up momentarily. Thanks for taking the time to register this - as I don't like to download third party apps for something so simple.

Just press on the keyboard control + shift + eject. That should do the trick.

Update: looks like someone already got the answer before I did. :)

Yep!

To turn the mac screen off just turn the brightness down to the bottom by the buttons at the top of the keyboard and that will turn the screen off altogether.
