How to Quickly Fix macOS Root Security Bug

If you’ve updated your Mac to the latest macOS High Sierra, you may have noticed a rudimentary security bug. This bug lets anyone log in to your computer using the username ‘root’ with no password. In this post, we’ll let you know regarding how to fix macOS root security bug.

The bug has raised security concerns among Mac users. Anyone who wants to adjust settings on your device just needs to enter ‘root’ as user name – no password, nothing else is required. In this way, any unauthorized user can gain all the administrator rights and change your password, customize settings for downloading applications, access keychain data, among others. Although it may not work the first time, attempting it several time will unlock the padlock, giving hackers access to your machine.

However, a hijacker is unable to use root and no password at Mac’s user login screen that appears at startup. The macOS bug only works once you’re logged in to your Mac.

Enough talk, let’s get to know how to quickly fix the root issue on macOS and stop hackers to access your Mac. Allow us to walk you through the process.
