Q: MacBook Pro (2009) Keeps restarting over and over.

Our Mac Book Pro (2009 model) restarting over and over. Already tried resetting memory and several different ways through the support. Can't run apple diagnostics.... not working. Do we need to replace the battery? Any other Ideas?

MacBook Pro (13-inch Mid 2009), OS X Yosemite (10.10)

    These instructions must be carried out as an administrator. If you have only one user account, you are the 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 and start typing the name.

    In the Console window, select

              DIAGNOSTIC AND USAGE INFORMATION System Diagnostic Reports

    (not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select

              View Show Log List

    from the menu bar.

    There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.

    If you don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.

    In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)

    Please don’t post other kinds of diagnostic report.

    I know the report is long, maybe several hundred lines. Please post all of it anyway.

    When you post the report, you might see an error message on the web page: "You have included content in your post that is not permitted," or "The message contains invalid characters." That's a bug in the forum software. Please post the text on Pastebin, then post a link here to the page you created.

    I made a mistake in the description of the post. The startup does not make it past the apple grey screen w the loading bar, then shuts down. Does the above still apply?

    No. What backups do you have?

    NO backups. we don't care about the data we just want to get it work again. a hard reset / reformat would be fine.

    See "Erase your drive and install OS X" on the support page linked below. It's likely that the internal hard drive is failing, in which case any improvement will be temporary. Without backups, you will eventually lose all data, no matter what you do.
