Last updated: Nov 30, 2022

Want to clean install macOS Ventura? You have come to the right place. Here we'll show you how to clean install macOS Ventura via a bootable installer.

Apple officially released macOS Ventura on October 25, 2022. The latest macOS comes with many new features, such as Stage Manager, Continuity Camera, richer Spotlight results, Safari Passkey, and more.

It's exciting to try out these new features, but if your Mac is running slow, or you want a bug-free experience, a clean install of macOS Ventura is a good idea.

This guide will walk you through what a clean install is and how to do a fresh install of macOS Ventura. Without further ado, let's get started.

6 Steps to Clean Install macOS Ventura

What Is a Clean Install?

A clean install is an alternative to an upgrade (in-place install). The former deletes all your files and settings, while the latter allows you to keep them.

Why Do I Need a Clean Install of macOS Ventura Instead of an Upgrade?

Upgrading to macOS Ventura is easy and all your data will be preserved. However, if your Mac is low on storage space, or your Mac is too old to upgrade, a fresh install is a good idea.

Here are the benefits of a clean install:

  • More stable macOS.
  • Faster running speed.
  • More available storage space.
  • More compatible applications.
