A clean install of Mac OS will restore your Mac to factory settings and reinstall new Mac OS on the computer, which is right for you if you want to give your Mac/iMac/MacBook a fresh restart.
This tutorial will explain to you how to clean install macOS High Sierra step by step. You can also apply these steps to clean install macOS Sierra, OS X El Capitan, or the older OS X version on your Mac.
Part 1: Clean Install Mac OS vs Upgrade Mac OS
Usually we install a new version of Mac OS by upgrading to the new version. For example, as macOS High Sierra is released, we download the new operating system from App Store and run the installer to get it on our Mac. By upgrading to macOS Sierra from Sierra, El Capitan, etc., current data on the Mac are preserved and you can use your apps, files, photos and other data right away once the upgrade is completed.
Clean install of Mac OS, on the other hand, will delete all current data on Mac's drive and install on the drive a with a fresh copy of macOS High Sierra. Comparing to upgrading to macOS High Sierra, a clean install is more likely to give your Mac a better performance and it is often used to fix Mac system problems, such as speeding up a slow Mac.
