It is, conditionally, at least on Darwin.

No, the reason is that inttypes.h looks like this on my system:

#if (! defined(__cplusplus)) || defined(__STDC_FORMAT_MACROS)
[...]
#undef __SCN_64_LENGTH_MODIFIER__
[...]
  #if defined(__STDC_LIBRARY_SUPPORTED__)
  [...]
   #define __SCN_64_LENGTH_MODIFIER__ "ll"
  [...]
  #endif
[...]
  #if defined(__SCN_64_LENGTH_MODIFIER__)
  [...]
   #define SCNdMAX     SCNd64
  [...]
  #endif	 =20
[...]
#endif

Hence, SCNdMAX is only defined if __STDC_LIBRARY_SUPPORTED__ is set which
is not the default for whatever reason.

No, #include <inttypes.h> works fine here.
