This is straight from a call log of a major computer company that happens to have technical support technicians in India and other points outside of the United States.

Problem Description: Client wants to know the MAC address for the computer. Advise client that I have no way of knowing or obtaining that information. Advise client that she would more than likely need to call Apple to see if they could point her in the direction of obtaining that. Client says that the MAC address is not a macintosh address. Client says that the MAC address can be obtained by doing an ipconfig /all. Client ended up disconnecting the call. During the call I believe I could hear someone else listening. Just before the call was ended by the client there was a something faintly said but I could not make it out.

Resolution: Advise client to contact Apple.
