I am starting to have my imac go a little nuts on me.  I was importing video from Iphoto to Imovie when the screen went dark and the message "  Your computer must be turned off now, Please press power button.


Has anybody else seen this know the cause?  It has happen before in other programs.  Any ideas??

    If you're able to boot, 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.


    ☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Console in the page that opens.


    Select the most recent panic log under System Diagnostic Reports. Post the contents — the text, please, not a screenshot. For privacy’s sake, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header and body of the report, if it’s present (it may not be.) Please don't post "shutdownStall" or "hang" reports.


    If you can't boot in the usual way, try a safe boot. The instructions provided by Apple are as follows:


    • Be sure your Mac is shut down.
    • Press the power button.
    • Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
    • Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).


    During startup, you’ll see a progress bar, and then the login screen, which appears even if you normally log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.


    Safe mode is slower than normal, and some things won’t work at all.


    Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.

    The computer does reboot with no problem, but will occasional shut down

    Uninstall the useless Symantec product according to the developer's instructions, then reboot and see whether there's any improvement.

    Ill give it a shot.  What points to the symantec product?  The above code is greek to me.

    What points to the symantec product?


    The fact that it's there.

    You may know Symantec by the name Norton Anti-Virus, Norton 360 etc. Search the forums for many problems associated with it.


    Link to Norton's uninstaller instructions:

    Linc Davis, you seem to be a bit of a guru. I'd appreciate you taking a look at my kernel headache, as below, if you have a moment.
