Currently the "Operating System" shown for MacOS Big Sur and newer are "10.16", when they should show versions and sub versions of 11, 12, 13, etc...
Example: Apple Inc., Mac OS X (10.16) (en_US)
It should show: Apple Inc., Mac OS X (13.2.1) (en_US)
Use `sw_vers -productVersion` to get the correct version
