My screen saver will not startup. I updated to Mountain Lion 10.8.2. There was an error that occured when I tried to update, saying the update did not happen, yet it did. After that, about two hours later, I walked away from the computer, had to do something. Whan I restarted the monitor, there was no screensaver active. I checked and the setting had not changed from the last time it was active. I tried changing the settings, even setting it to one minute to start, nothing. Some help please? Oh, btw, in the update info from Apple it mentioned several screensaver options, the only one I don't see is shatter, I see classic instead. Any clue?

Mac mini, OS X Mountain Lion (10.8.2)

    This has happened to me as well but my update completed just fine with no errors.  No screensaver or sleep, unless I manually force it in either state.  I restored my machine twice (from Time Machine) back before the update it everything was worked fine until I installed the update again. "pmset -g" is showing the the powerd process is preventing the computer from going to sleep.  I assume this is also causing the screensaver to not start.

    Hmmm.  Just checked mine and my File Vault and Firewall is off.  I turned on the Firewall, just to see, but to no avail.

    I've found that the screen saver will work once, on a restart. But then afterwards, it will cease to "kick in". So, I don't know if it's been working consistently for you, but the solutions I've found, which include: 1. Reapplying the 10.8.2 update, 2. Restarting 3. Repairing Permissions and Restarting etc.... really only work because of the restart, and in that case, the solutions don't fix the problem but only work once, and then for duration of the Mac uptime, the screen saver fails to work. Can anyone corroborate? Thanks.

    Found a solution that seems to have permenantly fixed things:

     

    I put my mac to sleep and then woke it.

     

    I know that sounds like a crazy solution, but this particular Mac had both the display and the Mac set to NEVER sleep. By simply putting the mac to sleep once (and probably never again)...the problem has now been solved.

    Hi

     

    In this forum many ppl including me are discussing the same issue as you are describing here.

     

    For me the issue is for a Mac mini late 2009 running 10.8.2 (upgrade to 10.8.2 made the problem appear). The issue are invoked when i use VNC to access the Mac mini wich leaves powerd preventing Idle Display sleep. Running 'pmset -g assertions' without the ' and scrolling upwards reveals a 1 after PreventUserIdleDisplaySleep. Killing that process makes the screensaver work again until next time I login to the computer via VNC.

     

    Irritating...

    Upgrade to 10.8.3 seems to have solved my issue.

    powerd no longer prevents screensaver from starting after screensharing to my Mac mini.

     

    Great news!
