A few days ago i bought a Macbook aluminum that was advertised as including Mountain Lion and Office 2011. This is my first Mac and i have found that Mountain Lion seems to be bound to one of the previous owners accounts. Now the Macbook came with no discs of documentation of any kind, so is there a way to deal with this that does not involve reinstalling anything and losing Office which i paid an extra 150 for. Will Mountain Lion deactivate or auto log out the account, if not is there a way for me to buy a new copy of ML without reinstalling and losing Office, also is Office also bound to this account. Can Apple help at all here?
