Tearing my hair. Out. Have done all the recommended testing and still can't track down the source of these kernel panics. RAM tests are fine. All of the Tech Tool Pro tests come out fine.


There's nothing specific I can do to invoke a kernel panic.  Sometimes it'll go for a day without having one, but when it happens it will usually have a series of them all in a row.


Latest crash log is below.  This one happened while running in Safe Mode.   Any help in interpreting what the crash log says would be greatly appreciated. Thanks.

    Reinstall the original memory and see whether there's any improvement. Be careful not to touch the gold contacts. Clean them with a mild solvent such as rubbing alcohol.


    The Apple Hardware Test or Apple Diagnostics, though generally unreliable, will sometimes detect a fault. A negative test can't be depended on. Run the extended version of the test.

  • Joe Bailey Level 6 Level 6 (12,165 points)

    Intermittent errors like this are notoriously hard to track down and require lots of patience. Linc Davis' comments about Apple Hardware Test or Apple Diagnostics apply to TechTool Pro tests as well. Memory is notoriously hard to test with software and IMO any memory test that runs in less than several hours is probably a waste of time and CPU cycles.


    Given what I am seeing in your log, a standard diagnostic test is to physically detach any and all external devices except a wired keyboard, a wired mouse, and monitor. That includes hubs. If possible turn off Bluetooth  as well. Then run normally for several hours or even days and see if any KPs occur.

  • jaybushman Level 1 Level 1 (0 points)

    Thanks for the replies.


    First thing I did was replace the RAM - OWC chips that I bought with their lifetime warranty.  But repalcing the RAM didn't change anything.  Didn't try cleaning with rubbing alcohol though. How likely is that cause problems?


    Apple Hardware Test turned up no errors - I know not a huge a surprise.


    Joe: I have to dig up a wired keyboard/mouse to try out your recommendation. What precisely is it in the logs that leads you to that conclusion? I've been tryign to learn how to read these reports better, so any clarification would be appreciated.


    Thanks again.

  • Joe Bailey Level 6 Level 6 (12,165 points)

    About all I am seeing in the log are references to kernel extensions (kext) and I/O devices. Secondly I know from long experience that kernal panics are often caused by external devices, even USB hubs, and that these devices may work for long times before turning to the darkside. In short, I am playing a hunch, but one that is informed by encountering many similar problems over the years. The test proposed used to be a lot easier and far more commonly performed, when everyone had wired keyboards and mice but with Bluetooth, I/R, and third party R/F keyboards and other devices, it has become a bit of a pain. For this very reason I always keep at least one Apple wired keyboard and mouse around for diagnostic testing if nothing else.

  • Linc Davis Level 10 Level 10 (147,070 points)

    Cleaning the contacts won't cause problems. Touching them with your fingers will cause problems.
