How to change a user's name on Mac
Mac name modification is divided into "full name" and "login name". The former is simple and the latter is cautious. Modifying the "full name" can be edited and saved directly through "Users and Groups" in the system settings, without affecting the system file path; while modifying the "Login Name" requires creating a temporary administrator account and adjusting the home directory permissions, which is complex and risky. In addition, users who are familiar with the terminal can use the command line to modify the "full name", but novices recommend using a graphical interface to ensure security.
