Well, you replaced the Popen() from the example with a check_call() which
uses a Popen instance internally, but does not expose it.
I recommend that you stick as closely to the example as possible until you
have a working baseline version. I'd try
textutil = subprocess.Popen(
["textutil", "-convert", "html", file],
stdout=subprocess.PIPE)
pandoc = subprocess.Popen(
["pandoc", "-f", "html", "-t", "markdown", "-o", markdown_file],
stdin=textutil.stdout)
textutil.stdout.close()
pandoc.communicate()
