How to Enable Root User on Mac

Developer Lem Ergin has discovered a serious bug in macOS High Sierra which lets anyone log into an admin account using the name root without any password.

According to reports, this method works when anyone tries to log in to an administrator’s account on an unlocked Mac. Besides, it also allows access to the login screen of a locked Mac.

Apple has been made aware of this issue and has released a temporary solution to the issue.
