Yogi can't Authenticate!

I think I'm going to cry. A week or so ago, I couldn't authenticate anything anymore. Whenever I tried installing an App, or pressing the padlock in system prefs, the authenticate window would show up, then crash. I then restarted my Mac just now and it crashes at the login windows, landing in a Darwin console.

I'm screwed? I ran MainMenu Batch tasks (disk perms, caches, logs, the works). I'll try a Disk Repair now, but I'm not sure it'll help.


Please save my Mac!?

Do you have DiskWarrior? I would use that next. It repairs the directory.

Archive & Install OSX - solved. Gah what a night.
