The issue is that chromedriver also needs to know where chrome is. In your case it is at a non-default path. So you need to specify the complete path to the Google Chrome
binary.
options = webdriver.ChromeOptions()
options.binary_location = "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome"
chrome_driver_binary = "/usr/local/bin/chromedriver"
driver = webdriver.Chrome(chrome_driver_binary, chrome_options=options)
Above code is what you should use
