A developer posted a screenshot on Twitter showing it was possible to obtain root access on Apple’s High Sierra without a password. The issue was first reported by Lemi Orhan Ergin, a developer in Istanbul, Turkey. Apple has released a fix for this issue, calling it a “logic error” Apple recommends that the root user be disabled after a password is set, which is solid advice in the long run, expecially if the account isn’t needed (hint: it isn’t)”]
