I have an external disk which I used to boot from, but I can't remember which version of macOS is installed. Where do I look in the directories to determine which version is installed? I am not booted into it, and I don't want to boot in yet, so can't just look in About this Mac. The System folder itself is dated 22 March 2022 so it's quite recent.
