Hi there,


I have recently experienced random freezes caused by Google Chrome or Firefox.


I've never had a single issue with Mountain Lion since the first installation however few days ago I have experienced the first freeze. I mostly use Safari however I sometimes have to test webpages on different web browsers. I started Google Chrome and load a usual webpage I've never had a problem with and the browser was suddenly frozen. I have to push the power button to restart my macbook pro. I was looking for a cause to this problem and couldn't find anything. Before the freeze I have updated Java to version 7. I have the same problem in Firefox however Safari would work without a problem. Also vmware caused the freeze as well.


I've tried everything but I couldn't find a solution to that. So I erased my HDD, installed a fresh copy of Mountin Lion. Nothing else was installed (no flash, java etc.) except Chrome however the freezes continue. Pls. help

MacBook Pro, OS X Mountain Lion (10.8.2), 2.3 GHz Intel Core i7, 10GB DDR3

    What exactly happens when it freezes, and how do you recover?

    thanks for your reply. Well the answer is simple The Spinning Beach Ball of Death. That happens when it freezes. I have tried to run Apple hardware test without any bad result.


    In google Chrome when I run some random webpages it freezes. Sometimes it freezes for a 15-30 second and the ball is just spinning. Any application, dock bar, menu bar, shortcuts, force quit.. nothing response at all. And after few seconds its over and everything goes like nothing happened. However sometimes the spinning ball continues for a long time and the only solution is to push the power button.

    The next time you have the problem, note the exact time: hour, minute, second.


    If you have more than one user account, these instructions must be carried out as an administrator.


    Launch the Console application in any of the following ways:


    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)


    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.


    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.


    Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.


    Scroll back in the log to the time you noted above. Select any messages timestamped from then until the end of the episode. Copy them (command-C) to the Clipboard. Paste (command-V) into a reply to this message.

    When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.

    Please do not indiscriminately dump thousands of lines from the log into this discussion.


    Important: Some private information, such as your name, may appear in the log. Anonymize before posting.

    You have a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

    Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

    *An SSD doesn't need to be zeroed.

    Thanks for your reply. I have found this thread

    http://www.insanelymac.com/forum/topic/282859-nvidia-1082-opengl-channel-excepti ons-freezes-9600gt285gtx/

    It seems that I'm not alone with this problem.

  • Linc Davis Level 10 (185,055 points)

    That's a site for people who waste their time trying to run pirated, hacked copies of OS X on PC's. It's irrelevant to your problem.

    This issue has cropped up for others in the past (see here: https://discussions.apple.com/thread/1065674?start=0&tstart=0), and while some have seen it fixed with a hardware replacement related to GPU problems with MacBook systems, others have managed to fix it with an OS reinstall. The problem in the past was related to an OS update that seemed to pull it out of the woodwork for many systems.


    The watchdog timer component of the Nvidia drivers is primarily for detecting when it is being used for driving a display, so the problem may be spurred by specific uses of the driver.


    Does your system have dual GPUs? If so, then try going to the Energy Saver system preferences and try toggling the system's automatic graphics switching to see if that helps prevent the issue. Optionally you can try using the tool gfxCardStatus to force the system to only use one GPU (either the internal or discrete one), and thereby avoid any bugs that could be happening when the processors switch.


    In addition you might try resetting the system's PRAM and SMC to see if those procedures help the situation at all:


    Reset PRAM: http://support.apple.com/kb/HT1379


    Reset SMC: http://support.apple.com/kb/HT3964


    If not then the issue will likely require servicing. Apple did have a replacement program for some select MacBook systems, but this has likely expired by now.

    Thanks for your reply.


    The gfxCardStatus did the magic. I first have tried to reset PRAM and SMC. It didn't help. Then I've tried to turn off the graphic cards switching in Energy saver. It din't help either. Then I've downloaded and installed the gfxCardStatus and set to one card (Integrated only) and no freezes afterwards. I have tried to set to discrete one but again freezes have contined.


    I therefore assume the NVIDIA GeForce GT 650M might be faulty.
