I am working on a friends MacBook6,1 and it randomly crashes with kernal panics. I've ran AHT, Disk Utility & Memtest86 but to no avail. He's an app hoarder with 184 items in his Application folder and I've got a hunch that may have something to do with it.



With just the Activity Monitor open, he's using about 1/4 of his installed 8GB and the hard disk is about half full. He's also got some Preference Panes that seem like they could potentially use up resources like Rapport and SneakPeakPro.


With all the crap he has on his machine, I feel like I could sit here for days trying to figure out where the conflict is. How do you diagnose a kernal panic?

    The next time the problem happens, note the date and time the problem occurred, then go to Applications/Utilities/Console and copy the log starting at the time of the crash. Paste the log in a reply. Please do not use a screen shot as they can be hard to read. If there are repeated runs of the same messages, please post only one run. Be selective about what you post and don’t  post huge amounts. Make sure there is no personal data visible. Information learned from Linc Davis.




    Trying running this program and then copy and paste the output in a reply. Please use copy and paste as screen shots can be hard to read.

    If you have more than one user account, you must be logged in as an administrator to carry out these instructions.


    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.


    Select the most recent panic log under the heading System Diagnostic Reports on the left. If you don't see that heading, select  


    View ▹ Show Log List


    from the menu bar. Post the entire contents of the panic report — the text, please, not a screenshot. In the interest of privacy, 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, spin, or hang reports.

    You have the MacBookPro6,2, the Edsel of Macs. It may be covered by this program:

    MacBook Pro (15-inch, Mid 2010): Intermittent black screen or loss of video

    Make a "Genius" appointment at an Apple Store, or go to another authorized service provider, to have the machine tested. The routine hardware diagnostics used by service providers may not detect the fault. There is a specific test for this issue.

    Print the first page of the panic report, and the support page linked above, and bring them with you.

    Note that the replacement program only applies within three years of purchase. If you wait beyond that date, Apple may refuse the service. In that case, you'll be quoted a price of about $300 (in the U.S.) for a depot repair. The model was discontinued in February 2011, so the replacement program will be ending quite soon.

    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.



    Sometimes the replacement part is also defective, so be prepared for that possibility.
    If it's too late for your unit to be repaired under the program, and you don't want to pay for a new logic board, you may be able to stop the panics by disabling automatic graphics switching.
    *An SSD doesn't need to be zeroed.
