\variable QOperatingSystemVersion::MacOSBigSur
\brief a version corresponding to macOS Big Sur
The actual version number depends on whether the application was built
using the Xcode 12 SDK. If it was, the version number corresponds
to macOS 11.0. If not it will correspond to macOS 10.16.
By comparing QOperatingSystemVersion::current() to this constant
you will always end up comparing to the right version number.
\since 6.0
