It’s still in the beta and testing stage. But, you can get the macOS 13 Beta version and install it. Yet, there are different ways to install macOS Ventura.

Why do You need a clean install?

You can install macOS Ventura in two different ways. You can either upgrade from macOS 12 to macOS 13. When you upgrade from macOS 12 to macOS Ventura 13, you don’t lose access to your files and other data. The other way is to cleanly download the macOS. In simple terms, a clean download means you are deleting the previous version of macOS and installing the other versions from scratch. However, when you clean install, you lose access to all of your documents, photos, apps, and other data. All your drives get formatted, and all the settings return to the default state.

We suggest you take a backup of your current Mac version with the Time Machine. Make sure you are choosing an external drive to take a backup of your current Mac version.
