The MacOS bash is very old; note the copyright date:

    % /bin/bash --version
    GNU bash, version 3.2.57(1)-release (x86_64-apple-darwin16)
    Copyright (C) 2007 Free Software Foundation, Inc.

A recent bash installed manually (not from Apple):

    % /usr/local/bin/bash --version
    GNU bash, version 4.4.18(1)-release (x86_64-apple-darwin16.7.0)
