It is how you want it to be. The marketing name is Big Sur. The version is 11.0.0. There is meaning to the separate numbers in the version, there’s a guarantee they aren’t going to remove api if the third number increases but they might if the second one increases. The first one only increases with truly big changes such as this move to ARM. Using an integer doesn’t work because point releases where the third number increases are not monotonous, 10.15.20 might be released while 11.0.0 is already out. Apple does maintain the previous release with security updates while there already is a newer current release. Note that Windows is a big mess with Windows 10 build 2004 (because they want to avoid confusion with Server 2003) which is version 19041.329, or perhaps 10.0.19041.329. It’s almost the same scheme but with large numbers you can’t remember and are hard to find in the documentation.
