I sold a G4 Powerbook to a friend about 2 years ago. I just looked in my 'Shared' drop down in the Finder sidbar and I can see the laptop there. Not sure why this suddenly happened. Is there anyway I can get rid of it? I'd rather not have to contact the person I sold the powerbook to- we're not so friendly these days. Any idea why this might have happened and how it can be fixed? I can network to it and even take control of the screen.
