OK I have a new-to-me PowerBook G4 and so I have had to authorize another computer out of my limit of 5. The first was my desktop, the second was my iBook which was stolen when my car was stolen a couple years ago. The third was my son's iBook which he has let me use for the last two years. Now I want to de-authorize the two iBooks. Is there anyway to do that and gain back the two authorize slots?
