I am only able to upgrade from Ventura to Sonoma. I don't want to upgrade, I would like to download the installer so that I can install Sonoma on a separate Volume instead of upgrading. Am I missing something? I only see an option to upgrade and the developer website only allows me to download a IPSW file. I have only 1 Mac and I am not sure how I can use the IPSW file to install macOS Sonoma. Any help would be much appreciated, thanks
