    I get this issue every few days or so ever since I started using this 2012 MacMini.  It is a media server connected to my TV via HDMI.  It only runs Plex (0.9.5.4) and usually happens when I've finished watching a show and start to watch another.  It is not consistent with specific shows.  I can watch the next show just fine after a reboot.

     

    The GUI locks up completely, can't connect to it via Screen Sharing, but I able to SSH into it just fine.  I ran top and nothing was using a lot of memory or CPU.  In fact, top itself was the highest usage.

     

    It doesn't have the option to disable graphic switching and the other suggestions listed in this thread didn't help either.

     

    The following appeared in the system.log

    The last 2 lines repeated every 2 seconds for about 15 minutes until I rebooted it.

    First time "freeze" like this happened to me today, I'm on a MBA 2012, no FCPX. And it wasn't really a total freeze, it was running and responding to e.g. Exposé but only at about 1 frame/3 minutes. And it was running hot, no fan kicking in. So a shutdown seemed the sensible thing to do.

     

    I just can't believe how buggy ML has been all the way through. I wish I had time to roll everything back to SL, that OS was rock stable!

     

    Console reports repeatedly:

    I still get this about once every day or so and it is VERY frustrating to say the least.

  • 168. Re: Mountain Lion Screen Freeze
    Simon Rioux Level 1 Level 1 (15 points)

    Also getting this freeze. Mostly happened when using Safari and having weebly.com opened in a background tab. Since I am closing tabs running weebly.com each time I flip tabs, I haven't had a freeze. Well, one freeze. Maybe twitter.com did it? Haven't had a freeze with Chrome though. But for others here, Chrome has been the culprit. And for others again, FCP-X.

     

    Very annoying.

  • 169. Re: Mountain Lion Screen Freeze

    I've resorted to using ONYX to clean up the whole system. Will check back in a few days to say if it fixed the problem or not. Fingers crossed! Usually Onyx has a good record of fixing obscure problems...

  • 170. Re: Mountain Lion Screen Freeze
    adam1232 Level 1 Level 1 (0 points)

    That's what I used, and I haven't had a freezing problem since. I'm not positive that Onyx was the solution, but I use Onyx a couple times a year now.

  • 171. Re: Mountain Lion Screen Freeze
    Simon Rioux Level 1 Level 1 (15 points)

    Well, so far so good. Everything that used to freeze my machine has been working flawlessly now.

     

    Seems like the answer to all problems in this thread is called "Onyx".

    I started getting the screen freeze about 2 weeks ago.  Only happens when I'm browsing the web - curser moves, audio continues if something is streaming (weird) -- but otherwise, machine completely unresponsive.  Have to do a hard reboot.

     

    After scanning the message boards, I thought maybe it was a video card or logic board problem.  Took it into the Apple store and they spent two days putting the machine through stress tests.  Conclusion:  hardware and data all checked out fine.  They reinstalled the OS and did not disturb any of my data. Took it home and the first freeze occurred after about 2 hours.

     

    This is what I have noticed:

    1. This only happens when I'm using a web browser.  First I thought it was Safari, but the freeze has happened on Firefox and Chrome as well. 
      1. The screen freeze has never happened when my browsers are closed.  I'm a graphic designer and often have InDesign, Photoshop, DreamWeaver and Illustrator open at the same time,  and I have never had the issue until I open a browser.
      2. The freeze happens when the only application open is a web browser.
    2. I cleared all my cookies and removed all my extensions on all browsers and I still get the freeze.
    3. I did a clean install of FireFox and Chrome and I still get the freeze.
    4. The machine does get very hot in the upper left corner when the freeze occurs, but the Apple genius I spoke with assured me the temps I'm seeing are well within the accepted range.
    5. Finally, I set up a new account on my Mac this morning to see if the issue replicated itself. I've been streaming video, I've got all three browsers open and that upper left corner has stayed cooler than when I'm in my own user account and I have not had a freeze all day.

     

    I'm convinced my freezing issue is related to my browsing software. 

    I'm suspicious the issue is confined to my user account and I'm wondering if I should create a new user account for myself. Can I recreate my user account without loosing data, but leaving behind the old user preference files? And will this affect my Time Machine and SuperDuper backups?

     

    Or Should I bite the bullet and wipe my drive clean and do a whole new clean reinstall of everything? (Gulp)

     

    I've noticed that other desktop and Macbook users have been having similar issues since Mountain Lion came out.  I've never experienced the hang until 10.8.4. 

  • 173. Re: Mountain Lion Screen Freeze
    Simon Rioux Level 1 Level 1 (15 points)

    Do like I did: use ONYX on your machine, and do a thorough clean up of all the system files with it. Erase everything that can be erased with this app, and reset everything that they allow you to. I haven't had a freeze since I put up the solution early July.

     

    You don't have to reset the computer after every system cleanup; just do all your business, and when all the tasks are completed, reboot.

     

    Give it a try!

    Don't take your frustration out on other users who are trying to help. If my answer doesn't resolve your problem, I'm sorry, I'm just a Level 1 user.

  • 175. Re: Mountain Lion Screen Freeze
    elkdog Level 1 Level 1 (0 points)

    Thanks for the tip Simon.  ONYX sort of worked!

     

    I noted that it repaired my user permissions for:

     

    "Library/Preferences/com.apple.alf.plist

    "System/Library/Frameworks/CoreGraphics.framework,Core Graphics"

    "System/Library/Frameworks/CoreGraphics.framework/Resources"

    "System/Library/Frameworks/CoreGraphics.framework/Versions/Current"

     

    I'm only using Chrome for web browsing now and I'm still occassionally getting the freeze every day or so,  but not the every-15 -minutes like I was getting with Safari.

     

    This problem seems to be restricted to only my iMac.  My Powerbook has never had the issue and it's running Mountain Lion and most of the same programs.

    Thank you Simon. I tried ONYX before, but didn't do a deep clean. I did so after read your post, and glad I did it.

     

    So far so good for 2 days, it is whole lot better than before. I am not sure the problem is gone, but positive to this solution.

     

    Cheers!

    I also only get this issue on my iMac. Seems to occur still about once a day or so. Macboook running exactly the same OS has no such problems. I still can't figure what is causing it. Very frustrating that the forced restart does not seem to generate any error report to send to apple.

    This problem still persists with Mavericks...
