    Hmm.. that's a new one.

    Have you designated what you want each corner to do?

    I've got the exact same issue. After using screen sharing TO my Mac mini powerd prevents display sleep.


    I hope they manages to get a fix to this in next release of 10.8 when I am using a plasma TV with my Mac mini.

    I moved the hot corner from the NE corner to the SW corner and got it to work.  I have a 30" slaved to the iMac 27" to the right so perhaps the NE corner being "next" to the 30" monitor is somehow screwing it up.

    Hey guys! Happy christmas and a happy new year to you all.


    Hopefully the new year will bring a resolution to our problem!


    I just wanted to note something i noticed in relation to this screen saver not engaging issue. If my machine is not connected to the internet, the screen saver works as normal i.e. turn wifi off and plug out ethernet cable.


    Do we all have this in comman, or is this just me?? I was thinking that if this was comman, maybe theres an app that we all have that is preventing the machine from sleeping?


    Whatever it is, its STILL really upsetting my happiness!

    Im having the same issue as everyone else. I was able to get the screen saver to work 1 time by unchecking the "wake for network access," but after that it didn't work again. i have now set all for hot corners for screen saver since I have a plasma TV and dont want any burn in. I put in a service call request to apple, but I'm in the mil and living in South Korea, so i doubt they will call me. I just dont know why it is so hard to fix this.

    Same story over here. Just bought a new Mac Mini and use it to replace my old one as a media centre. Screensaver stops working after using screensharing to the Mac Mini with ML 10.8.2. I hate this. Very bad for the television.


    Hope that Apple will solve this problem!!! FIX.


    (did made a feedback)

  • corvairkid Level 1 Level 1

    So does anyone have any info on when 10.8.3 will be released?

    (I know Apple doesn't usually tell us too far in advance.)

  • Xofb Level 1 Level 1

    I use the minimac with Plex as a mediacenter. When Plex is turned on even after screensharing my screensaver works. It's not the solution, but it is something.

    I have found in my case, playing certain video content in Safari is what causes the screen saver to no longer activate, even after the video has finished and if I have shut down Safari.  Looking via terminal, after a clean boot, prior to playing video the PreventUserIdleDisplaySleep is set to 0.  After playing video and then shutting down Safari, PreventUserIdleDisplaySleep is set to 1.  At that point screen saver no longer kicks in.  I go into activity montior and kill powerd, which then sets the PreventUserIdleDisplaySleep back to 0 and screen saver once again kicks in.  powerd actually spawns a new task when I kill the previous running one.  I don't know enough about video content to understand why kind of video is causing the issue as it is not all video content.  I uninstalled adobe flash player and the video content I was using as my test case would stil play in Safari so guess it is some type of content that Safari can handle.

    Additional information.  It appears that playing video within iTunes as well also leaves the PreventUserIdleDisplaySleep set to 1 after exiting iTunes.  Again, powerd is the holder and killing the process clears the issue.

  • gungholady Level 1 Level 1

    In my case, I don't use iTunes nor watch videos on Safari. It is a matter of using the computer for a period of time that does it. I will certainly be glad when this issue is resolved.

    I assume it is not worth my while contacting Apple about this?


    I've just purchased a new iMac, and I'm pretty annoyed about the screensaver not functioning as it should. I had no problems until about the fourth day I was using the machine - all of a sudden, I'd go away from the machine for half an hour or so, and come back to find the screen just as it was, despite the screensaver being set to activate after five minutes.


    This is a real pain for me, as I stream a lot through Apple TV and I would like the screensaver to actually work when I ask it to.


    I've sent Apple feedback about this - any word from them about this? (Haven't had time to read all eight pages of this thread.)

  • Len Gold Level 1 Level 1

    Hopefully mrgage will confirm that his beta version of 10.8.3 is still proving to be a fix. All we can do in the meantime is wait for 10.8.3 to go on public release and hope it works for us all.

  • ganchan Level 1 Level 1

    hi all, my experience. i had the problem on my mac upgraded sice 2008 with all updates and new systems, after mountail lion the screensaver and monitor sleep stop to start.

    than i've intalled a new ssd 256 cucial m4 and installed a fresh moutnail linon than updated and voilà, the screen saver and monitor sleep have start again to work.

    that's it.


  • inspiredgl Level 1 Level 1

    I saw where someone mentioned changing the hot corner on one of these posts (could have been a different thread because I've been trying to figure it out for 2 days now and have read a lot of threads). My original hot corner on my older iMac was the top right corner. So when I had this same problem after installing new iMac and transferring my files over to it I tried switching my hot corner. I moved it to the bottom left. For two days the screen saver has been working. I'm not positive this is a long term fix but so far so good.
