Screen saver locks up computer

When my wifes 1-year old iMac goes into screen saver, it has a tendancy to lock up, requiring a hard power-down and restart. This has only started recently. It has the latest Lion updates installed. I've seen a few similar comments but no one seems to have posted a solution. Does anyone have a suggestion on how I can prevent this from happening?

I can't really say until more info is learned about the issue.  If it's a screen saver that's got a corrupted plist then it may be a simple as getting rid of the plist.  If it's a screen saver that's just incompatible with lion then get another screen saver. 
My philosophy on screen savers is that if a screen saver has a problem it is just not worth trying to find out why with some many other screen savers to choose from.

  • Cannot log in back after screen saver locked the computer

    Hi there,
    We have a domain environment with Windows 2012 R2 and a Windows 2003 domain controllers and Windows XP and Windows 7 clients. We have setup a GPO for screen saver which lock the computer after 15 minutes idle. In the last few weeks on some Windows 7 computers
    after the screen saver locked the computer the users cannot log in back. Error message come up with Username or password is incorrect. 
    I've tried to reach the computer through RDP but same error came up even tried to log in as domain admin. I could log in as domain admin locally (switch user option) but as a user cannot. I've tried to restart Netlogon, Workstation and Server services but
    nothing happened. In the event viewer no related error message. The only way to login back as a user to restart the computer. It is not really good solution as they opened lots of things which wasn't saved.
    Anyone has any idea or experience to solve this issue?
    Many thanks

    Hi,
    Since you could login with Domain Admin locally, it should didn't have problem with Netlogon service and other logon correspond service. It seems like the account itself problem.
    When this problem occures, have you tried to use other computer logon with the problematic account for test? If other normal computer also had same problem when using the account. It's should your Server authenticate problem. If not, it maybe the domain
    account profile problem, you can try to remove the account and readded it for test.
    If there was any updates, please feel free let us know.

  • How to screen saver lock

    On PC's you can lock your screen when you walk away and must enter your login password to unlock.  Is there a keyboard sequence where you can lock your Mac the same way?
    Thanks... Gary

    This process works well, and is easier than a key stroke:
    Under the "Security and Privacy" tab in System Preferences, click the box next to 'Require password [immediately] after sleep or screen saver begins." Then, under the "Mission Control" tab, click "Hot Corners" in the bottom-left corner. Choose a corner (I have mine set for bottom-right) and click the tabbed menu. Choose either 'put display to sleep' or 'start screen saver.' When you are about to leave your desk, just drag your mouse to the bottom-right corner until the screen sleeps or your screen saver kicks in. Simple as that!

  • Screen Saver Lock-out

    Our WMS 2011 Premium server boots and then after the association of the mouse and keyboard the screen saver starts and then simply moves when the mouse moves or the keyboard is touched.  
    There is no way to get around the screen saver and the system is not accessible from any other station.
    We can start the system in safe mode and log in, but not apply changes or update the system.

    I had this happen to me and I ended up solving it by disassociating my LAN client, installing all of my USB stations, and then associating my LAN client again. Evidently, when the LAN client was connecting, my system would lock up. By adding all of my USB
    stations first and then the LAN stations last, it solved the issue for me.
    Also, I experience screensaver lockup when my Windows was set to put my monitors into sleep mode after a minute. I turned that off in the USB Power settings and the lockup went away. With this issue, I could turn off the client and turn it back on to jump
    start the system.
    Also, have you looked at this link to see if the SRCShell user account has been deleted?With WMS2010, at least, Microsoft says you'll have log-in issues if that account is deleted.

  • Screen Saver Locking up DVD Player

    While watching a DVD in full screen, the movie stopped playing and the application locked up. A force quit was able to get out of it, but it happened once again. After setting my screen saver to never go off the problem stopped.

    OK. Since the issue is specific to your original user account, you can proceed in two ways. One is to log into your new account, make a list of the preference files (plists) located in /username/Library/Preferences/, including any in the ByHost subfolder, log back into the original account, move everything on that list into a newly created folder on the Desktop, log out and back in, and see if the problem goes away. If so, you can copy the ones in the Desktop folder (one at time) back into /Preferences/, restart, and see if the problem returns. If so, you've identified the corrupt/conflicting one. Continue with all of them until isolating the bad ones. That'll save you the trouble of resetting preferences.
    The second way is much more detailed and I'll not burden you with the steps unless the above doesn't fix the issue.

  • Screen saver locks up, won't allow changes

    After bringing everything over from the previous iMac, went to set up the desktop and screen saver system preferences.  Desktop worked like always, but when you go to make a selection for which screen saver you want, goes into the endless spinning ball and the only way to get out of it is a force quit.  
    Apple help guy said to dump the com.apple. file, that worked once and then back to locking up.  Reinstalled Leopard from the Mac disk, but with the same result.  Did show up on the first boot-up but then back to normal next log in.  
    Any ideas?  (went to search the tip section but couldn't figure out how to get a question in)

    I'm not sure I understand the current behavior: you say it still locked up, yet that the canned screen savers now work. Can you explain?
    One thing others have suggested for a similar issue is to make sure the iLife Support 9.0.3;/a> update is installed, but I'm not sure that applies to you.
    Also, make sure any custom screen savers you have are not PPC-only ones.
    Well, those were the three magic words—downloaded the update, rebooted, and the screen savor pref worked perfectly, just like it should!! Don’t know why this upgrade never showed up in the software update from Apple, it certainly should have.
    Here’s what it was doing in more detail: The desktop side of the pref worked with no problem, but when you went into the screen saver side you could do one thing--say pick one of the canned saver and close the window. But if you went to scroll down to get to the ‘choose folder’ option and opened that up, the beechball came on forever, and the only way to close the window was a force quit, which meant you lost any changes you wanted.
    Thanks for your quick replies, do appreciate it. Been a long time Mac user (1985 to be exact—what a change from the original to the new!), and one of the things I’ve always liked about the experience is the discussion forums. Hope anyone else having this problem can find the answer here by searching

  • Touchsmart Envy 23 screen saver locks with photos

    Screen freezes when trying to exit photo screen saver.  Screen saver works fine with pictures rotating, but locks up when I try to get out of it.  Changed back to bubbles and other generic windows screen savers and it works fine.  Only when in photo mode does it do this...?????

    I understand the PC freezes when exiting the photo screensaver. 
    Try this Microsoft FixIt and let me know what happens.
    http://go.microsoft.com/?linkid=9726338&entrypointid=MATSKB
    It does seem to be related to something that is in the photos library/folder since other screensavers work fine.
    What is the product number of the PC?  This can be found in the same area of the serial number.
    NOTE: Do NOT provide the serial number.

  • Screen saver (lock) based on location

    I have several locations on my Macbook Air.  When I am at work, I want the screen saver to come up after a certain interval and lock my screen however, when I am at home, I would like to disable the screen lock but still am OK with it dimming and the screen going dark.  Is there a way to do that?

  • Track or log screen saver locks/unlocks

    Hello,
    I'm looking for a way to track when folks unlock their screen savers. Is there a program or log file that can assist me here? I need to be able to do this so I can track when users are logging into their machines when they arrive to work. Most users don't logout of their machine, so the screen saver is my best option I think. I manage about 18 mac minis running 10.6.
    Suggestions are welcome for tracking times other than this route as well.
    Thanks in advance,

  • Screen Saver Locks on Startup

    I am having this exact problem that was posted in 2012. Is there any fix out there?

  • HUGE SECURITY HOLE IN LOGIN FROM SCREEN SAVER

    One of the options in the security panel permits a user to require that a username and password be entered to login once the screen saver locks your account.
    The option is "Require password to wake this computer from sleep or screen saver"
    Although one would assume that the credentials required to wake the computer is the username/password of the account that was being used when the computer went into sleep mode or the screen saver. WRONG!!! Anyone with an account on the machine can enter their username/password and wake the computer and voila that user now has control of the machine as the former user. That's right you guessed it HUGE security hole.
    Anyone thinking that they can wake away from their machine and have the screen saver or sleep mode protect their account after a specified period of time is sadly mistaken. Anyone with an account on the machine can enter their own username and password and drop right into your account right where you left off.
    Can you believe this stuff? No warning, no release note to tell you of such a poorly designed "security" option.
    Apple please fix what must have been an oversight or at least tell people about this intentional design BEFORE they find anyone can wake the computer and become you as a user.
    Thanks,

    I never think that way. A more secure lock is ensured by using the screen lock feature of the keychain.
    Can you believe this stuff?
    Not sure what stuff you refer to.
    No warning, no release note to tell you of such a poorly designed "security" option.
    Would you believe that anyone can access your computer? Stolen computers are regularly started up without much problem.

    You are writing to other users like yourself here, not Apple.

  • Security problem: Waking from screen saver botched in 10.5.5

    When using my MBP, I like to have my screen saver as simple computer lock in that it requires a password to wake the computer from sleep or screen saver (option in the Security system preference pane).
    Since the update to 10.5.5, my computer just wakes from sleep or when in screen saver mode, without demanding a password to be entered, even though the option is checked in the pane. I did an immediate SMC reset after the installation because the fans were acting oddly, and a PRAM zap just now to see if it'd do any good with this problem.
    Has anyone experienced something similar?

    I had this happen a few times back when I was running Tiger. I was able to fix it by going to Homefolder/Library/Preferences/ByHost and deleting all of the com.apple.screensaver.xxxxxxx plist files, and then logging out/in.

  • I want screen saver on and iTunes playing

    I want to play music through my stereo while I am showing my house.   I set up my iTunes on my computer, turned off the energy savers, set up my screen saver to require a password, and moved my mouse to the corner to start the screen saver.
    After a while, iTunes stops.   I got caffeine and tried it (set indefinate).
    How can I keep iTunes playing, but have my computer secure while I am away from the house?

    OK, I added it there.   But it doesn't seem to be so much about iTunes, as it does about screen saver locks.

  • Podcast screen saver

    I have a screen saver (locking screen) of Harry Potter that displays while I listen to a podcast.  I cannot figure out how can I change it.  It is not wallpaper and seems to have been set automatically when I loaded the copy of the movie (HP7 digital copy).  Normally what displays is an image from the podcast and I find this very annoying that it changes the system on me.

    Hi...
    Thanks, I thought there was going to be something like the visualizer (I knew windows has something) that’s why I asked....
    I know I can do a few things at once - but - who get’s the audio? I know I could bring something up on YouTube or something from the internet; but I’m thinking there’s going to be an audio issue. I haven’t really tried - but I just know there's going to be an issue.
    Is there a way of “designating” audio while several visuals are playing?
    In any event - the visualizer is just great - thanks.

  • ScreenTime Screen Saver Engine 3.6.2

    I just installed a screensaver from a third party. However, I get this message when I try to run it:
    'You cannot use the ScreenTime Screen Saver Engine 3.6.2 screen saver on this computer. Contact the developer of this screen saver for a newer version.'
    Any ideas?

    How come it worked for a couple of days, but then failed? Sorry for being a dunce.
