Is this even possible? Would it effect OSX in any way aside from no access to my very passwords? Or am I just being too paranoid about the fact that my laptop carries with it every bit of security information to get into my email and other worthless online items I own. I downloaded the First Aid program becuz I was having very annoying problems with my keychain with only 2 users on this laptop, but I guess it fixed it. I still dont ever want to have to see this thing again nor have it save any passwords. You are all the genius's you tell me your opinion.
