Sorry for the title, but here's the thing. I bought used Mac with Mac OS X 10.5.8. I have again lost my Leopard installation disk, I know it's there somewhere However, since this thing already has fully updated Leopard I'm thinking about not reinstalling at all. There was some Remote admin and sharing settings enabled and I of course disabled them. Seller did not tell me his password but I googled the instructions how to force new account creating by using few commands so I do have admin account now. I deleted seller's account and files, but it did not reset those remote admin etc. settings so I wonder what else there is to look for? Remote admin sounds bad even though I believe seller just forgot those and his intention was not to do harm and when he doesn't know my IP I'm not sure is it even possible to do harm. Is there anything else to look for? I will check and remove any possible unnecessary application of course altough it seems that there is none.
