I am currently getting occasional 'crashes' while running OS X 10.9 on an Early 2011 Macbook Pro. The crashes very much resemble the Blue Screen of Death on Windows (i.e. it happens suddenly, and it triggers an instant restart).

Here is a crash report from the most recent crash. Can anyone see what might be going on?

  • Tips for reading these logs, you want to pay attention to the sections where it says: "Kernel Extensions in backtrace:", "last loaded kext at", and "loaded kexts:". – Fyrefly Jul 11 '14 at 14:27

It appears you have KeyRemap4MacBook installed which may be causing the problem. If you restart with the [shift] key held down does it make a difference?

Holding the [shift] key down at startup until you get to the login screen and see 'Safe Boot' at the login window prevents 3rd party extensions from loading which will help you determine if it's the KeyRemap4MacBook extension that's causing the problem.

More on Safe Boot here: http://support.apple.com/kb/HT1564

I would hazard a guess that you updated the OS to 10.9 without updating KeyRemap4MacBook to a Mavericks compatible version.

I looked again, you appear to be running v 9.0 which is the latest version. My guess then would be a messed up preference file or cache.
