Part 1. The Problems with MacOS High Sierra and iOS11

MacOS High Sierra and iOS 11 are the latest operating systems developed by Apple. While the former is for iMac, MacBook and MacBook Pro, the latter powers iPhone and iPad. They are a product of the company’s commitment to constant innovation and elevated user experience.

High Sierra aka macOS 10.13 boasts of new technologies for a more efficient video streaming and graphics. The Metal 2 is a game changer as it unleashes the full potential of Mac’s graphics processor. On the other hand, iOS 11 claims to make mobile usage more powerful and personal. The Drag and Drop feature and augmented reality games and apps are just a portion of what the new OS has to offer.

But time and again, technology rears its ugly head. Initially, when Apple announced the release of the two new OS, it created excitement among users. It doesn’t come as a surprise though because of their features. However, soon after their release, users have reported serious problems.

For MacOS High Sierra, it was a security issue so grave that users wondered how Apple’s developers failed to catch that before its release. Here’s a rundown of how the bug in macOS High Sierra is bad:

  • Anyone with a physical access to a Mac can get to its files and accounts.
  • Someone who has remote desktop access to your device can log in as an administrator and have full control over your system. He can delete important system files, change admin passwords, and remove system accounts.
  • The MacOS High Sierra security gap allows a person to log into an admin account on an unlocked Mac.
  • Via the login screen of a locked Mac, an unauthorized user may access your computer.
  • All these can be done by entering “root” as the username and leaving the password field empty. When the enter button is clicked multiple times, a user can eventually log in.

iPhone users have faced several issues with iOS 11, including an auto-correct glitch where the letter ‘i’ is replaced by an ‘A’ followed by a question mark. However, there are other things to worry about more:

    • Battery drains out fast.
    • Apps crash repeatedly.
    • Software update fails or does not complete.
  • Worst of all, partial or complete data loss occurs after a successful or failed iOS11 update.

Part 2. Fix Apple Problem #1: MacOS High Sierra Root Security Bug

Needless to say, Apple has always put their customers first. Without fail, they have promptly come up with new updates to fix the problems. For instance, a new patch for macOS High Sierra was released less than a day after the critical bug was discovered. Though it can be downloaded from Mac App Store, Apple announced that it will automatically be installed on Mac running on High Sierra 10.3.1. As for those running the older version 10.3, it would have to be manually installed. However, users have reported that after they have installed the security fix, an update from 10.3 to 10.3.1 would undo the patch.

The good news is that the newest macOS High Sierra 10.13.2 has been recently released to address security and stability flaws. Download the latest update from Mac App Store to make sure you no longer get affected by the bug.

We’ll never know though if hackers can still find their way despite the new fixes Apple has provided. Nevertheless, it won’t hurt to tweak your Mac’s settings so your device and data stay secure. Here are tips to further protect your Mac from unwanted access.

Fix #1: Create a Password for Your Root Account (Highly recommended).

The MacOS High Sierra root security issue exists only because there is no set password for the root account. By creating one, nobody can have superuser access to your device’s system except you.

  1. Click the Apple icon and select System Preferences.
  2. Choose Users & Groups then click the lock icon.
  3. You will be asked to input the credentials for an admin account on your computer.
  4. Click Login Options. After that, select Join.
  5. Select Open Directory Utility.
  6. From the new window, click the lock image and again, enter an administrator name and password.
  7. Look for the menu bar and select Edit. Click Enable Root User.
  8. You will be asked to set your password.

Fix #2: Disable Guest Accounts.

Although this is not a necessary step if you have already set a password for the root account, this can reinforce security for your Mac.

  1. Head to System Preferences and choose Users & Groups.
  2. Enter your admin account username and password.
  3. Select Guest User and then disable Allow guests to log in to this computer.

With these simple troubleshooting tips, you can prevent yourself from falling victim to a hack due to the MacOS High Sierra bug. However, don’t forget to visit Mac App Store and install High Sierra 10.3.2 immediately.
