Updating your operating system is essential not only to enjoy new functionalities but also to protect your device against vulnerabilities and ensure compatibility with the latest apps. Whether you’re a casual user or rely on your Mac for work, understanding the update process can make a significant difference in your overall experience.

Navigating the update journey from High Sierra can seem daunting, especially with multiple macOS versions available and varying hardware requirements. Many users hesitate to upgrade due to concerns about data loss, system compatibility, or simply not knowing where to start. However, with the right guidance, updating your Mac can be a smooth and straightforward process that breathes new life into your device.

In the following sections, we’ll explore the essential steps and considerations for updating macOS High Sierra 10.13.6. From preparing your system to choosing the right update path, this guide will equip you with the knowledge to confidently move forward and make the most out of your Mac’s capabilities.

Preparing Your Mac for the Update

Before initiating the update process from macOS High Sierra 10.13.6, it is crucial to ensure that your Mac is adequately prepared to avoid interruptions or data loss. Begin by verifying the compatibility of your Mac model with the newer macOS versions you intend to install. Apple typically supports Macs released within the last several years, but some older hardware may not support the latest OS.

Next, back up your data thoroughly. Use Time Machine, Apple’s built-in backup utility, to create a complete snapshot of your system. Alternatively, consider third-party backup solutions or manual backups of critical files to an external drive or cloud storage. This precaution safeguards your files in case the update encounters issues or requires a clean installation.

Check the available disk space on your Mac. Major macOS updates can require anywhere from 15 to 20 GB of free space. Insufficient storage will prevent the update from proceeding. To free space, remove unused applications, clear cache files, or transfer large media files to external storage.

Ensure your Mac is connected to a reliable and stable internet connection. Interruptions during download or installation can cause update failures. For laptops, connect to power to avoid shutdowns during the process.

Finally, update your current system and applications to their latest versions on High Sierra. This step reduces compatibility issues post-update and ensures a smoother transition.

Downloading and Installing the macOS Update

Once your Mac is prepared, proceed to download the update from Apple’s official sources. The macOS Software Update mechanism has evolved, so the steps vary slightly depending on the target macOS version.

  • On macOS High Sierra 10.13.6, open the App Store application.
  • Navigate to the Updates tab.
  • Look for available macOS updates such as Mojave, Catalina, or Big Sur.
  • Select the desired macOS version and click Download or Get.

Alternatively, you can download the macOS installer directly from Apple’s website or the Mac App Store if you prefer a manual installation or need to create a bootable installer.

After downloading, the installer will launch automatically. Follow these steps:

  • Agree to the software license terms.
  • Choose the target disk where macOS will be installed.
  • The Mac will restart and begin the installation process, which can take 30 minutes to over an hour depending on the system and update size.
  • The Mac may restart multiple times during installation.

Do not interrupt the process by powering off or closing the lid during installation. Once complete, the Mac boots into the updated macOS environment.

Managing Update Issues and Troubleshooting

Despite careful preparation, some users may encounter issues during or after updating macOS from High Sierra. Common problems include installation failures, slow performance, or application incompatibilities.

If the installation stalls or fails:

  • Restart your Mac and attempt the update again.
  • Use Safe Mode (hold Shift during startup) to perform the update, which disables unnecessary extensions.
  • Reset the NVRAM/PRAM by restarting and holding Option + Command + P + R.
  • If problems persist, consider using macOS Recovery to reinstall the system without erasing data.

For performance issues post-update:

  • Check for application updates compatible with the new macOS.
  • Clear system caches using built-in utilities or third-party software.
  • Review and disable login items that may slow startup.

If specific applications stop working, verify their compatibility with the updated macOS version. Some older apps may require updates or replacements.
