I have my Macbook pro since february. and i experience freezes at least once a day. I brought it to apple service, they got my motherboard changed but it didn't change a thing. I thought it happened when i was using chrome, now i switched to safari but it still continues to freeze. I got my system checked couple of days ago, everything seems to work fluently. If you have any ideas what to do please help because i am a designer and i lost couple of my projects because i had to restart my computer due to the freezing.

MacBook Pro with Retina display, OS X Mountain Lion (10.8.4)

    This has happened to a few users. I'd suggest reading this thead preruse the issue:



    gfxCardStatus has solved the issue for several people; post here with your results.

    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.

    Step 1

    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. If you don't see that menu, select

    View Show Log List

    from the menu bar.


    Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time after  you had the problem. Select the messages logged before the boot, while the system was unresponsive or was failing to shut down. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). Please include the BOOT_TIME message at the end of the log extract.

    If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same 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.

    Step 2

    Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

    I have more or less the same problem: mouse moves around but every other GUI element is frozen and up to now the only way I found to deal with this is to hold the power button and cold start it.

    The logs say:

    • 18/07/2013 1:43:50.000 AM kernel[0]: stampWait: Overflowed checking for stamp 0xbea25a on MAIN ring: called from sleepForTimeStamp
    • 18/07/2013 1:43:50.000 AM kernel[0]: timestamp = 0xbea259
    • 18/07/2013 1:43:50.000 AM kernel[0]: GPU hang:
    • 18/07/2013 1:43:50.000 AM kernel[0]: Trying restart GPU ...
    • 18/07/2013 1:43:50.000 AM kernel[0]: MAIN ring is NOT waiting on an event
    • 18/07/2013 1:43:51.566 AM com.apple.launchd[1]: (com.apple.DumpGPURestart) Throttling respawn: Will start in 9 seconds

    Curiously, I repaired permissions which found something related:

    • Group differs on “private/var/db/GPURestartReporter”; should be 0; group is 80.
    • Permissions differ on “private/var/db/GPURestartReporter”; should be drwxr-xr-x ; they are drwxrwxr-x .
    • Repaired “private/var/db/GPURestartReporter”

    There is no panic report, since I used the power button.
