[0/2] Disable unavailable features on older macOS

Some features require APIs introduced in a recent version of macOS. Currently,
this is not checked anywhere and so either the build will fail (if building with
an older version of Xcode) or will throw a warning and then crash if run on an
older machine. The correct way to handle this is with availabilty checks. The
checks are a clang extension that only works on Apple platforms but these files
are only built for Apple platforms already and link with Apple frameworks.
