// The version returned by macOS depends on the SDK which the software has been built against.
// When built against the 10.15 SDK or earlier, Big Sur returns 10.16 for compatibility with previous numbering.
// When built against the 11.0 SDK, it returns 11.0 for forward compatibility.

// It's impossible to load real SystemVersion.plist when linking with old SDK, i.e. when building for Intel CPU
// Any attempt to read this file is redirected to SystemVersionCompat.plist silently
// Workaround with the external process is needed in order to report correct macOS version
