I can’t speak for the issue generally as I don’t know what this code
does, but this particular check looks incorrect to me.

sw_vers doesn’t exist on GNU/Linux, and probably other platforms that
GNUstep runs on, so you can’t just use a check for NS. Probably you
need to check for Darwin, which should work on terminal only versions
of Emacs too.

    (string-equal system-type "darwin")

(There may be other ways to check, this is the only one I know.)
