Screen Saver on 10.8.2 Fails to Activate

My Mini does the same thing since the update. Very annoying since I now have to log off everytime I leave my desk in fear that someone would have total control over my computer. I sure hope this gets corrected quickly.

I have the same issue with my MacBook Pro 3.1. Going to try reapplying the update. Will post back with results.

same issue here With my iMac 2012 model 2011, done a fresh install, but that did not work, Have been searching for days for the problem, but without result, Hope it will be resolved quickly,

I resolved this issue with the help of Apple tech support. What we did was to create another administrative user account, and log into that account. We changed the time to start screensaver from the default 20 minutes to one minute and it went into screensaver. Then we logged out and logged into the account with the problems. The screensaver problem cleared up. Apple said sometimes creating another account fixes the problem for the other accounts as it did for me. Hope this helps.

To all I tried the fix above logged in to another user that I allready had made a while back changed the settings in that user account and logged out opened the other user and after one min the screensaver started working again and has been working for the last 5 hrs. So I tried a restart logged in and it is still working..the only other change I made was in Energy Saver preferences was display sleep from never to 15 min.. ALL IS WELL hope this helps Jim P

I have a new iMac running 10.8.2.

Sometime after upgrading from 10.8.1, my screen saver stopped working.

Apple tech support advised me to reset my PRAM and then reset my SMC.

This seemed to fix the problem yesterday, but when I checked this morning, the screen saver was not working again.

Frustrating.

I just got off the phone with Apple Support again.

This time I was advised to do the following:

1. Open Energy Saver in System Preferences.
2. Uncheck "Wake for Network Access".
3. Shut down computer.
4. Start-up in Safe Mode by holding the Shift Key immediately after pushing the Start Button.

After doing this, the screensaver worked.

I then restarted the computer normally and the screensaver has been working normally... so far.

I have manually installed the 10.8.2 update.

First time machine backup 10.8.1 put back,

10.8.2 After downloaded and installed manually,

and for now it works fine for me,

Follow-up to my previous message.

Screen saver still working A-OK.

Some of us have also been reporting in this thread:

https://discussions.apple.com/thread/4318987?start=0&tstart=0

but it has been incorrectly marked as solved. So have moved comments to this thread.

Hello corvairkid, tried your latest Apple recommendation, same result as always, worked for 2-3 hours then back to not working again.

I am now pretty convinced that this is some kind of software bug as the Apple Support person I spoke to yesterday basically agreed with.

He suggested re-installing 10.8 seeing if the problem goes and then re-installing 10.8.2 and seeing if the problem returns. He also requested that we send feedback to Apple so that the software team are properly aware and can work on a fix.

I haven't had time yet to do the re-installs but will at some stage and see what happens.
