I have been experiencing random system crashes for the last several weeks. The monitor screen will gray out from top to bottom and terminal-like text will follow. The text will end with "Waiting for external debugger."

The crashes occur when I am actively using the machine, the screen saver is running, and when the machine is asleep.

The crashes are disconcerting, especially with an OS "touted by all, including Apple, as one that never crashes." My Windows laptop, in contrast, has never crashed.

Has anyone else experienced similar crashes and what did you do to fix the problem?

Thanks,
Frank

    What do the crash logs say? You can access the crash logs via the Console, which is in the Utilities folder.

    All my logs are empty as I "cleaned" the system last night. I will check the crash log following the next crash, assuming there will be one.

    Thanks for the suggestion.

    As if on cue, the system crashed. Here are the contents of the Apple Crash Report and the Panic Log:
