What's wrong with my computer console?

There's too many, but some of them look like this,.

23/01/2013 08:34:57.000 kernel[0]: MacAuthEvent en1 Auth result for: d8:c7:c8:2d:a7:00 AP busy fail

somebody in that link says I should trash

System/Library/LaunchAgents/com.apple.afpstat.plist

but then someone else says don't do it.

This is my first computer and I don't want to break it.

Does anyone know if this is true?

That's what it said in the thread, but they didn't explain what lsboxd process is, and the first person thought otherwise, so I'm not sure they know or are just guessing. That's why I asked if anyone know if its true.

What is lsboxd process?

IF your read my post you'll see I already explained the symptoms, and just coming out with a 'stop worrying about it' answer is patronising and shows you don't know the answer. If you don't know what the symtoms are, what is it you want me to "stop worrying about"?

I mean install again.

Thanks for your repsonses, but in English words like 'fail', 'deny', 'unable' are common words for errors and problems.

Where is the safe mode?

never mind, i got it.
