RuntimeError: Error, unable to determine correct filename for 64bit macos

Reproduce the failure with quickstart.py, then trace the startup path through instapy/browser.py and the installed webdriverdownloader code at get_geckodriver and get_download_url. The work is done when the 64-bit macOS quickstart completes startup without the filename-detection RuntimeError.
