I've got a 15 inch Retina Macbook with 16GB RAM

My default browser is Chrome

Mostly, I use my Macbook Pro for browsing the net and watching video content online.



My Macbook Pro keeps freezing on me, especially when I'm dealing with videos content on the web (from: youtube, gorillavid, ... ).

It been happening once every other day, and it seems to be getting worse and more frequent since the last OS update that i did.



When it does freeze,the rainbow wheel start spining but nothing happens after that!!



To fix it, I have to hold down the power botton for few seconds untill the computer shuts off and restarts again.

I'm really tired of doing this and restarting/reloading the computer and the web pages every time the computer freezes..



So, Why is this happening and how can i fix it permanently ?

MacBook Pro (Retina, Mid 2012), iOS 5.1.1

    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 when 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.

    Any or all of the following third-party system modifications may be contributing to your problem:







    If the panic is recurrent, I suggest you uninstall them, one at a time, according to the developers' instructions, to see whether you can identify which one is at fault. A conflict between modifications may be involved. Reboot and test after each uninstallation.


    Back up all data before making any changes.

    The System just froze on me again


    I have uninstalled PdaNet, Little snitch and screenflow

    and it's safe to say that Parallel is not the problem, cuz 1000s of people use it and they're not having any problems of the sort.


    So why is it still doing that???


    P.S. these "System freezes" always accrue when I'm dealing with video/flash contant online, i.e. Exiting a full screen mode, entring a fullscreen mode.

    The graphics adapter is faulting. Make a "Genius" appointment at an Apple Store to have the machine tested. You may have to leave it there for several days.

    Print the first page of the panic report and bring it with you.

    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.
