According to reports, XNU’s CPU family identifier previously used for the Westmere family (which Homebrew mislabels as the Arrandale family) is now being reused for one of Apple’s M1 SoC models. Resolve the conflict by splitting the list of CPU families and adding a microarchitecture check. Sources for the values: - https://github.com/Homebrew/brew/issues/7857#issuecomment-728739049 - https://en.wikipedia.org/wiki/Comparison_of_ARMv8-A_cores - Direct messages
