Sorry, but that wouldn’t work.
TargetConditionals.h is created by Apple as part of SDK construction, so the
TARGET_* macros are defined directly (#define TARGET_OS_OSX 1),
In a newer macOS SDK, both TARGET_OS_MAC and TARGET_OS_OSX are defined and set
to 1, and TARGET_OS_MAC covers OSX (macOS), IOS, TV, WATCH and others.
In an older macOS SDK, TARGET_OS_MAC is defined and set to 1, and none of the
others are defined at all.
This is from the current TargetConditionals.h:
