I have a new 2013 iMac 27". I understand the difference between display sleep and computer sleep.

Is there any way to tell if the computer is sleeping as opposed to just the display sleeping?

Also, I have a late 2012 mac mini. On the mini, under energy save, there are separate slider controls for display sleep and computer sleep.

On the iMac there is only a slider for display sleep, none for computer sleep. Both are running 10.8.5. Why the difference?

There should be a pulsing white light when the computer is asleep.

The same is available under System Preferences for the iMac under OS X.8.5. Computer sleep and Display sleep. And that pulsing light is on the rear of your iMac.

Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

Interesting Harry, they moved it to the rear? I know for sure my late 2007 iMac does not have a white pulsing light anymore in front.

The iMacs have a pulsating white light when in sleep mode? Mine (model prior to the super slim iMacs) definitely does not. That Apple logo in the back is dead.

A pulsing white light in the back of an iMac? Which one Harry? My 2011 iMac does not have one and I don't believe the newer ones do either. I just put mine to sleep, turned off the lights and looked.... nada.

I'm flabbergasted to hear that newer iMac's no longer have a sleep light!!!

I did some research...and it seems the "trick" folks now use to know if their iMac is asleep or not is to push down the "caps-lock" button on the keyboard. If the iMac is awake...the caps lock will be green...if the iMac is asleep...the caps lock light will not be illuminated.

Oops too early and no java first answer. Thinking back on my beloved Mac Pro about the flashing light and not the iMac.

Put your ear to the top of the iMac - they are quiet, but there is a difference between running and sleeping.

Thanks for all the information.

When I woke it up and asked if it was asleep, it just growled at me

1. There is no light anywhere on my 2013 iMac 27".
2. The CapsLock trick works. I push CapsLock on my Apple Keyboard and the green led on CapsLock comes on. I manually sleep the machine and the green led goes out. This is useful to figure out what is happening. However, it's not particularly useful generally for me since I always disable the CapsLock function and have it be another Control key. (I'm old and learned on an IBM PCAT keyboard--best keyboard ever.) Also, one has to remember to push the CapsLock key to turn the light on to see it go out . . .
3. Also, for Harryb: My mac mini and my 2013 iMac are both running 10.8.5. However, the Energy Saver preference in System Settings are different as show in the attachment. I don't understand nor like this feature.

What I am trying to do is stop the machine from sleeping during the day (it runs Plex Server, if it sleeps, Plex Server isn't available), but have it sleep overnight. I ticked the box in Energy Saver to "Prevent computer from sleeping automatically when the display is off". Then I used the scheduling function to schedule sleep at 11:00 pm and to wake at 6:00am. My hope was that it would not sleep during the day, but the schedule would override the not sleep and put it to sleep at 11:00pm and wake it up at 6:00am.

After doing this, pmset shows the following:

Terrys-iMacesktop tbrown$ pmset -g
Active Profiles:
AC Power -1*
Currently in use:
standby 1
powerbutton 1
womp 1
halfdim 1
hibernatefile /var/vm/sleepimage
autorestart 0
networkoversleep 0
disksleep 10
sleep 0 (sleep prevented by )
autopoweroffdelay 14400
hibernatemode 0
autopoweroff 1
ttyskeepawake 1
displaysleep 15
standbydelay 10800
Terrys-iMacesktop tbrown$ pmset -g sched
Repeating power events:
wakepoweron at 6:00AM every day
sleep at 11:00PM every day

Seems right. However, it went to sleep overnight, but didn't wake up when I tried to use Plex at 7:00AM. I had to manually wake it with the keyboard.

Now that I know how to tell if it is sleeping, I'll verify that it doesn't sleep during the day.

Any ideas?

I tried this, but my ears detect no difference. Perhaps the fusion drive makes it a bit quieter?

Could be. My 2011 iMac has the stock HDD. Sorry!
