So I get asked this a lot and on my day to day setup of any Apple silicon mahcine this is one of the first things I do in setting up a new build of macOS. All you need to do is open up Terminal paste in this command
“softwareupdate –install-rosetta”
press returned It prompts you to confirm by typing A press return and Rosetta is installed very quickly. You can also try this terminal command.
“softwareupdate –install-rosetta –agree-to-license”
Its a very quick install and should not give you any issues in installing it on a Apple Silicon Based machine.
