If you're looking to give your Mac a fresh start or get rid of unnecessary files and data, a clean install may be the perfect solution. With Setapp, you don't need to search the internet for individual apps; all the necessary tools are available in one place.

Before we begin, let's clarify that there are two ways to clean install macOS High Sierra: on a startup drive or on a non-startup drive. If you're unsure which option is best for you, don't worry - this step-by-step guide will walk you through both methods.

Clean Install on a Startup Drive

If you choose this method, your Mac won't be wiped clean, but only the system will be reset. This approach is less intrusive and more lenient than the second option. To proceed, make sure you have a USB drive available for the installation process.

Clean Install on a Non-Startup Drive

This method involves deleting all files and data during the process. If you're using this method, ensure that your files are backed up before proceeding.

Before starting the clean install, consider the following:

* Clean up your system to prevent any issues during the installation.

* Back up your important files and data in case anything goes wrong.

To complete the clean install procedure, follow these steps:

1. Download the macOS High Sierra Installer from the Mac App Store.

2. Prepare your Mac for the clean install by checking that it can run Apple's new operating system.

3. Follow the installation instructions provided with the installer.

By following these simple steps, you'll be able to perform a clean install of macOS High Sierra on either your startup drive or non-startup drive. Remember to choose the right option based on your needs and preferences.

With Setapp, you can easily get started with your clean install and have all your apps and data ready for use in no time.
