Preparing Your Mac for the Update

Next, back up your data. Use Time Machine or another reliable backup method to create a complete copy of your system. This protects you from potential data loss in case the update process encounters issues.
Ensure your Mac has sufficient free storage space. High Sierra requires approximately 15-20 GB of available disk space for the installation process. You can check your available storage under the “Storage” tab in “About This Mac.”
It is also recommended to update your existing apps and software to their latest versions to avoid compatibility problems post-update. Visit the App Store and update all critical applications.
Finally, connect your Mac to a reliable power source and stable internet connection. Interruptions during the update can cause serious problems.
Downloading macOS High Sierra
Once your Mac is ready, download the macOS High Sierra installer from the App Store. Follow these steps:
- Open the App Store application on your Mac.
- Search for “macOS High Sierra.”
- Click the “Download” or “Get” button to start downloading the installer.
- The download size is approximately 5.2 GB, so the download time will depend on your internet speed.
- After the download completes, the installer will automatically launch. If it does not, you can find it in the “Applications” folder as “Install macOS High Sierra.”
Avoid running multiple heavy applications during the download to ensure a stable and fast process.
