As such, the check the existence of the compile-time identifier is not sufficient here. MAC_OS_X_VERSION_MIN_REQUIRED should be used instead. (I should have suggested the use of MAC_OS_X_VERSION_MIN_REQUIRED at the first place since it can be used regardless if the identifier is for a constant or a symbol. My Bad.) Regards, Akihiko Odaki
