Hi guys, do you know a way to put a Mac out of order by deleting (and easily restore) some essential system files? I need to attack my father's Mac (we had a really bad discussion), so I need to be able to easily restore the system after seeing him begging for mercy . By the way, system is Mountain Lion. Thanks.

I gotta say, seriously dude? How many more places are you gonna post this at? Are you seriously wanting to get at your Dad or you got something more sinister up your sleeve?

Your Dad is gonna beg for mercy? Really? If you were my son and you messed my computer cause you didn't like what I told you to do, I'd burying my foot in your rear.

Ok delete this thread -.-

Well seriously dude... I mean damn. I'm not trying to slap you but you've asked this several places so far and seems nobody wants to tell you that. I'd suggest you do some reading about OSX and how it works...
