This is because in MacVersion.pm you run `system_profiler SPSoftwareDataType` and then parse the output with a regular expression that assumes the macOS version will be 10.x, an assumption which is no longer true as of the release of macOS Big Sur version 11 this month.
Note that it would be much simpler and quicker to get the macOS version using `sw_vers -productVersion`.
