I do not understand.

Or have any difference between original and refurbished macbook pro?

There are no specification differences between a 'new' MBP and a refurbished one. They both come with the same warranty and telephone support.

Ciao.

I do not know of a way to do that. If you are near one, contact an Apple store and ask your question.
