Macsonic said: High Sierra will still work even after security support have stopped. We’ll just have to be vigilant and perform security measures, install an anti-malware, anti-virus software. Though even with the newest OS receiving security updates, we would still need to be vigilant and implement security measures. (If your Mac is running a very old version of OS X, you must install Snow Leopard 10.6.8 first, in order to get a version of Apple App Store that can download High Sierra.

, 2017, reporting the discovery of a major security issue in Apple’s MacOS High Sierra operating system. It seems that a bug within the OS made it possible for anyone to access a High Sierra computer by exploiting a simple login loophole.Usually, when you login as a user on a Mac, you must enter your username and password. On machines running High Sierra, though, it was possible to enter “root” as the username, leave the password field blank, and then click the login button several times in succession. This process allowed someone to access a Mac computer running High Sierra—even if they didn’t have an actual username or password – and worse yet, as root!Security For Mac Running High sierraThe vulnerability garnered global attention on Tuesday, November 28th, when software developer Lemi Orhan Ergin tweeted a message to Apple Support to report the problem. Apple quickly responded to Ergin’s tweet and set to work developing a patch to fix the issue. Apple has now released an update meant specifically to eliminate the “root” username exploit from working in the future. The update was available for download as of Wednesday morning.Apple said that the update would install automatically on any Mac running macOS High Sierra 10.13.1, so there should be no need for most users to download and install the update manually.In a statement to the site MacRumors, Apple expressed remorse for the vulnerability. “Security is a top priority for every Apple product, and regrettably we stumbled with this release of macOS,” the statement read. Apple also apologized to users and noted that “Our customers deserve better.” The company is currently auditing its software development processes to find out what went wrong and ensure that similar issues do not affect future OS releases.Mac High Sierra was initially released to the public on September 25th of this year. This “root” username bug, it seems, existed in the operating system for two months, but no one knew about it. So far, there have been no reports of anyone exploiting the vulnerability for malicious purposes. Apple said it was not aware of the vulnerability until Tuesday when Ergin sent out his tweet.Users of previous Mac operating systems—including High Sierra predecessor MacOS Sierra—needn’t worry about the issue. The bug affected only machines running the High Sierra OS.Free Filed under 10.13 High Sierra, Apple, Mac OS X, Security News

If you keep your macOS regularly updated, you probably noticed that Apple had released Security Update 2019-002 for Sierra and High Sierra twice. The first one was on March 25th, then another Security Update 2019-002 update was released on March 29th.

This incident has caused a lot of confusion among Sierra and High Sierra users, with some of them thinking that Apple made a mistake with the announcement and decided to push the update to a later date. Others thought that it might be a naming error committed by Apple engineers.

Well, these speculations are all wrong. There really were two versions of Security Update 2019-002 for High Sierra and Sierra that Apple released just a few days apart. This is because the initial update, which was released last March 25th, was incomplete, so Apple had to follow it up with another update.

What Is Security Update 2019-002?

Security Update 2019-002 is a combo security update for macOS released last March 2019. The first update addresses several kernel-related problems that will allow malicious apps to execute arbitrary codes. It also fixes a vulnerability issue with the macOS Feedback assistant using improved checks and additional validation. Security fixes were also released for Wi-Fi, Time Machine, and memory vulnerabilities.

If your computer freezes during the installation of the update in view or fails to restart and complete the update, try our step-by-step guide below. This guide works for Security Update 2019-002 and all other macOS updates.

Step 1: Restart Your Mac.

It is better if you boot into Safe Mode so that there are no other third-party processes running. Just hold the Shift key when starting up your Mac to boot into Safe Mode. Complete the following steps in this mode to ensure success in the troubleshooting procedures.

Step 2: Delete Old Downloads.

MacOS automatically deletes update files after installing them. But if you are unable to complete the update, these files might be lying somewhere in your system and interfering with the process.

To delete old update files, try these steps:

  1. Look under the Applications folder. If your computer is running High Sierra, the filename should be SecUpd2019-002HighSierra.dmg. For macOS Sierra, the filename of the update file is SecUpd2019-002Sierra.dmg. You can also search for these files in Finder if you can’t find them in the Applications folder.
  2. Search for the OS X Install Data folder in Finder and delete it.
  3. Go to the /Library/Updates This folder is used to store system update files that have not yet been installed. Delete the contents of this folder.

Step 3: Update via Mac App Store.

Once you’ve deleted the old downloads, proceed with the installation of the updates via the App Store. To do this:

  1. Click the App Store icon from the Dock or go to the Apple menu, then click App Store from there.
  2. Click on the Updates tab.
  3. Click on Security Update 2019-002 to install the update. You can also click the Update All button if you wish to install the other updates as well.

Make sure to install the first Security Update 2019-002 update dated March 25, 2019 before installing the second one dated March 29, 2019. After downloading these updates, restart your system and check if the update proceeds without errors.

Follow the steps below to reinstall macOS:

  1. Boot into Recovery Mode by pressing Command + R during startup.
  2. Release the keys when you see the spinning globe, the Apple logo, or the firmware password dialog box.
  3. Select Reinstall macOS from the options, then click Continue.
  4. Follow the onscreen instructions, then choose the hard drive you want to use for the installation.

Wait for the process to be completed. It is normal for your Mac to restart several times or to see a white screen during the installation. Once the update is completed, your macOS should be updated and good to go.
