How to disconnect registration information from my macbook pro

[jincheker]

Hi, everyone

I've bought a macbook air recently, so I'm going to sell my macbook pro.

But the problem is: in the "about this mac" -> "service", my service information and all my personal information is there too. People can easily track my information using serial number.😱

My question is: can I remove all these information? 😕
