Não tenho certeza se é isso que você está procurando, mas, ao deixar o System Preferences > Accounts
, você pode alterar o Full name
para qualquer um dos usuários disponíveis sobre os quais você tem acesso.
A Apple tem um artigo da base de conhecimento explicando como o nome abreviado e o nome do diretório de um usuário podem ser alterados.
Vou citar as instruções para alterar o nome abreviado do artigo para as versões do OS X 10.5 e posteriores:
- Enable the root user.
- Log in as root.
- Navigate to the /Users folder.
- Select the Home folder with the short name you want to change, and rename it just like you would rename any folder. Keep in mind that the shortname must be all lowercase, with no spaces, and only contain letters.
- Use the Accounts pane in System Preferences to create a new user with the short name that you used in the previous step.
- Click OK when "A folder in the Users folder already has the name 'short name'. Would you like to use that folder as the Home folder for this user account?" Note: This will correct the ownership of all files in the Home folder, and avoid permissions issues with the contents.
- Choose Log Out from the Apple menu.
- Log in as the newly created user. You should be able to access all of your original files (on the desktop, in Documents, and in the other folders of this Home).
- After verifying that your data is as expected, you can delete the original user account via the Accounts pane of System Preferences.
- Disable the root user.
