I have a "rescued" Mac which I'm trying to rehabilitate. The other day I added myself as an account administrator. I don't know if this has anything to do with the problem. When I click on "About This Mac" I am unable to go the next step, i.e., get the "more information" link to work. All I get is a beep. I tried logging in under the account of the original administrator and I get the same result. Suggestions would be appreciated.
