Hi, I would appreciate help a lot. I bought a new bigger HD for the Macbook. Installed it from the old one externally. then I replaced it physically and now I seem to have 2 user accounts and not beeing able to see all my old music, movies, files etc. under the new HD. Is there a way to fix this issue or should I just re-install everything? I would also like to have just one user account instead of 2. thanks for all the help !
