itunes cannot authorize computer

[markpenn]

Hi guys,

 

I made a ccc clone copy for my mac system, and the target mac's (different hardware) 's itunes cannot authorize the target computer

 

with -50 error.

 

and i cannot play purchsed songs.

 

must be the change of hardware.

 

anyway I can reset my target's mac's itunes?

 

thanks.
