I've got a question. I've got a computer here at work that is one of the computers that I've authorized for my iTunes account. They were having problems with this particular computer and bought a new computer to replace the old one. The plan is to transfer all the data from the old computer to the new one and let someone else use the old one in the company. My question is, I still need to deauthorize the iTunes account from the old computer. Is this possible or even necessary. If it is, how is it done?
