There was a separate load command for the minimum version of each platform:
 - LC_VERSION_MIN_MACOSX
 - LC_VERSION_MIN_IPHONEOS
 - LC_VERSION_MIN_WATCHOS
 - LC_VERSION_MIN_TVOS
They have been replaced with LC_BUILD_VERSION, which encodes both the platform
and the minimum required version.

If your binary does not have LC_VERSION_MIN_MACOSX, it will have
LC_BUILD_VERSION instead. This is the same information, just encoded
differently. You should be able to decode this with `otool -l`.
