Updating Your MacOS High Sierra: A Step-by-Step Guide

Are you running MacOS High Sierra (10.13) and wondering how to update it? In this article, we'll walk you through the process of updating your MacOS High Sierra to ensure you're running the latest version with all the latest features and security patches.

Before You Start

Before you begin the update process, make sure you have a backup of your Mac. This is crucial in case something goes wrong during the update process. You can use Time Machine or another backup method to create a copy of your startup drive.

Checking Compatibility

To start the update process, you need to check if your Mac is compatible with the latest version of MacOS High Sierra. You can do this by clicking on the Apple menu at the top left corner of your screen and selecting 'About This Mac.' From there, you can check the compatibility of your Mac with newer versions of MacOS.

Downloading the Update

If your Mac is compatible, you can download the macOS upgrade installer app from the official Apple website. You'll need to use Safari only to do this. Click on the 'Download' button on the MacOS High Sierra page and follow the prompts to download the installer app.

Installing the Update

Once downloaded, double-click the 'Install macOS' app in your Applications folder to begin the upgrade process. The installation process will start automatically, and you'll be prompted to restart your Mac.

Alternative Method: Using Terminal

If you're experiencing issues with the graphical installer, you can use the command-line tool called softwareupdate. This method is more advanced and requires some technical knowledge.

To use softwareupdate, open Terminal from the Applications > Utilities folder and type the following command:

```

softwareupdate -l

```

This will list all available updates for your Mac, including the latest version of MacOS High Sierra. You can apply these updates when you're ready.

High Sierra offers several neat improvements over previous versions of MacOS, including improved security features and a more intuitive user interface. Additionally, it lays the foundation for future features like virtual and augmented reality (VR and AR).
