I suppose the solution here is to patch it in the Port to inlclude “Availability.h” instead?
As per its comments, Availability.h is for the use of OS headers to declare what is available. Programs wanting to check what is available should use AvailabilityMacros.h.
Check MAC_OS_X_VERSION_MAX_ALLOWED when it matters which SDK you are building against (and thus which features have available declarations). If you instead care about the oldest OS version that the program may run on (and thus which features need a runtime availability check), use MAC_OS_X_VERSION_MIN_REQUIRED.
__MAC_OS_X_VERSION_MAX_ALLOWED is from AvailabilityInternal.h, which as its name suggests is only intended to be used internally (by Availability.h).
