Apple just released macOS 11.1 (which should hopefully fix all the problems on my M1), and this breaks an implicit assumption by
juce::SystemStats::getOperatingSystemType - which the update was expected to be a
11.0.X (Apple stayed on version 10 for two decades, are they going to jump version every year now?).
Everyone is likely to hit this assertion as the constructor of
juce::TopLevelWindow happens to call it.
Note how it also renames
juce::SystemStats::MacOSX_11 to reflect this naming scheme shift by Apple.
