Mac OS Kernel Panic after Update to Mac OS X 10.6.8

If your Mac is not booting after updating to Mac OS X 10.6.8 (like it just happened to me), you can try the following for a quick troubleshooting:

• Start your Mac in Safe mode (pressing shift during startup), if it that doesn't work, try the verbose mode which should be pressing CMD + V during startup
• After startup you should get a System Crash Report, indicating what caused the mess-up. My Crash Report looked something like this:
• The important information here is right on top, com.metakine.handsoff.driver, so its a pretty good guess that Hands Off is fucking the Kernel in an unpleasant way during startup.
• Well after you got a similiar information about (most likely) some driver problems you have 2 options:
  • Get out your Time Machine Volume and move back in time before the Update, reboot in normal mode, install an update for the driver/App that is causing the Crash (in my case, I installed an Update for Hands Off, gladly they had one...) and finally redo the Mac OS X Update
  • If you don't have a Time Machine Volume (which you really should have, and if not, GET ONE NOW!!!!), you could try to install an Update while in Safe Mode (which you really should ONLY do if you know what risk that implies or you are REALLY, REALLY desperate....) and reboot again in normal mode.
• If everything is up & running again, relax, congratulate yourself and have a beer!
