I have a Mac that someone asks me to help them sell. They already wiped the hard drive and put a fresh installation of macOS on it. Upon boot, it's at the "Welcome" setup with no users intialized yet.

Is there an easy way to see the System Information and version of macOS currently installed on this machine without creating a new user? I'd like to leave this machine in a clean sate without having to re-wipe the hard drive with a new installation.
