I recently purchased my sister's 1-year old Powerbook G4 after she upgraded to the new Macbook. I love it, but can't figure out how to change the owner's name and passwords to be mine instead of hers. I don't want to completely format everything and start over because she has many extras (like Microsoft Office for Mac) installed and I don't want to lose them. (She is currently living in Africa and can't mail me the discs for the additional programs.) Is it possible to make these changes or am I stuck until I can get the discs and format and reinstall everything? I did add myself as a user and then as the administrator.
