Hi guys,


I have been having serious problems with the software on my MacBook Pro. My Mac crashes all the time without warning, at least 4 or 5 times a day. I have no idea what could be causing the problem. I have attached my latest crash report as I do not know what to do look for. Everything else seems to be working just fine except that OS X crashes. I have already tried resetting the PRAM and verifying my boot drive, as well as disk permissions, on which no errors.

I have made a copy of the latest crash report, but cannot find a way to attach a text doc to this message.


Thanks for any help!

MacBook Pro, OS X Mountain Lion (10.8)

    So my issue seems to be a recurring kernel panic, based on the messages that are displayed upon startup. Here is some of the kernel panic report:

    Oaky I think I might have misdiagnosed my problem. I do not receive a message that says "You need to shutdown your computer". What happens in my case is, the computer just reboots instantaneously without warning. Not sure if this indicates a kernel panic.

    I am having exactly the same problem. My MacBook Pro reboots instantaneously, with no warning and for apparently not reason. At first I thought it was Chrome, so I began to use Safari but it doesn't matter, it crashes anyways and I don't get a crashing report.

    What to do?

    Do you by any chance have CrashPlan? I do, and it seems like the majority of the time when a KP happens, it happens while the CP backup engine is running AND I happen to have a USB device (such as an external hard drive) plugged in. I called AppleCare to see what they had to offer in the way of advice, and they had me through the usual troubleshooting motions: update OS if there are any available (there wasn't), verify and repair the disk permissions through recovery (there were no errors), try booting in safe mode, and resetting PRAM, all of which didn't work. He then basically told me to back up my hard drive and format and reinstall from scratch, and manually migrate only my documents, media, and apps; no system files such as the user library folder or any other system/preference folders. Overkill probably, but I have done this many times so it wasn't a big deal for me. He explained that the problem is likely due to external 3rd devices, such as USB hard drives, and that I should investigate and try to update the drivers for these. Meanwhile, I have formatted and reinstalled, but did not install the user library directory, CrashPlan, nor java (which CrashPlan depends on). So far I have not any KP's, including when USB devices are attached.
