Screen Saver on 10.8.2 Fails to Activate

I upgraded four Macs to 10.8.2 (iMac, 2 MacBook Pros and Mac mini) and the Mac mini is the only one where the screen saver stopped working. Too bad, because this one is our media center, hooked up to a projector and a small 12" display. The 12" display stays on, displaying the photo montage screen saver (Vintage Photos), and works really nicely as a photo frame.


I've tried a bunch of things, including repairing permissions, restarting, changing screen savers, and it started working once, but then it stops working again.


Seems like theres a bug in the timer that tracks mouse inactivity or something, as the screen saver fails to activate.


Any thoughts?

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.

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.

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.)

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.

I bought my mac mini about 3 weeks ago, and have had this problem since day one. Thought it was related to my Microsoft ARC intelipoint software (screensver worked after uninstall, but no not workign again) ive tried everything. how do you you roll back update? Its easy in windows but can this be done in OSX? (new to mac, made the switch)


I can however get the screensaver to work with hot corners but still not the most practical fix.


Hopefully apple has a fix coming soon.
