Clean Install macOS Ventura

Old Toad, your advice is outdated and clearly demonstrates that you have never performed a "clean" instal of macOS.

If it's a new M1 Mac and it came with Monterey there's no reason for a clean install. I've been using Macs since 1984 and have never done or needed to do a clean install, particularly with new Macs.

To do a clean install you would need to create s bootable installer according to this Apple document, Create a bootable installer for macOS, boot into it, erase the boot drive fully and run the installer. It's a lot of effort.

I imagine if all one does is email and surf the web with Safari, then no, you might never have needed to do a clean install. Things are different now with Apple Silicon Macs and a clean install may be a thing of the past for the new Macs, or so I hear. Regardless, one way to skip Monterey when doing a clean install is to download Ventura and make a bootable drive to install it from as outlined in the following Macworld article.
