My iMac seems to not want to sleep. I have tried to source other similar problems and did resolve the issue seemingly. Now it again won't automatically trigger the computer or the display to sleep. I tried to reset the default on the screen saver/ power options… no solution thus far …
Suggestions?
Thanks and have a great weekend 🙂
iMac, Mac OS X (10.6.8)
Hi Hugh,
Generally it's some attached USB or less common a FW devcice, what all is attached?
Does it sleep if you choose sleep under the Appl icon?
It sleeps manually and the screensaver works on command. Currently I only have my speakers via headphone jackplugged in to it with the keyboard/mouse. I have set the computer to never sleep with the display sleep at 1 minute.
I have set the computer to never sleep...
???
Why would you expect it to sleep then?
this course of action was suggested in a similar post with the same problem. Once I confirmed it did not work I reset the energy saver option to default.
Ah, now I get it! 😊
Though it seems the opposite, I wonder if it's a pmset thing?
See if it's related to this...
The 2012 macs (and later apparently) not waking normally from sleep after hours being in sleep. (noted here ...

The sleepimage file still reappears even if never slept. Delete it (hibernate off, etc) - within minutes its back.

About iMac sleep...
id say yes but the opposite...at first everything worked fine but since I installed xcode and a tutorial for xcode light sleep has not started on queue. If I select sleep from the appl drop down menu it works, as does the screensaver with voice command
Well, I had two widgets that displayed a couple of streaming webpages; one was a NOAA sattelite image loop, the other a webcam from USTREAM: I removed both of those widgets and reset the SMC. I then reset the energy saver to put the display to sleep and put the computer to sleep after 1 minute, then restarted the machine and it went to sleep automatically and on queue. So, I set the energy saver to default and restarted once again, waited ten minutes and it worked.
Great work, thanks for the report! 🙂
Thanks for leading me in the right direction! Funny how the exact opposite indication leads to a solution. Goes to show that thinking outside of the box is a course of action that can produce results. 😀 Im pretty sure that the widgets in question had not fully suspended thus preventing the trigger to call sleep although I ofcourse am not sure. I spose I could test the theory by adding the widgets back 😉 Some other time, maybe.
Have a great weekend!

My only advantages are that I only graduated from the 6th grade, & like to break things... requiring learning! 😉
it seems as if it is acting up again.. same problem... wont initiate sleep or screen saver
How old is this Mac, & has it ever not had AC power for long periods?
I'm wondering if the PRAM Battery is not holding the PRAM.NVRAM settings up.
its an iMac 7,1 so its a few years old. previously the machine was left in the closet for about a year before I got it second hand.
zap it with command p , r ?
I reset the PRAM and it works.
