selenium chrome driver select certificate popup confirmation not working

I also had problems with accepting the warning for using a signed certificate. The solution of @eskoba worked like a charm. The functions are NOT final, because I let the enter button press for 10 times. I made this, because the webdriver needs a long time until it actually calls the url. In the meantime he starts pressing already.

In Python:

def threaded_function():
    #Calls the website
    browser.get(url)

def threaded_function2():
    #Presses 10 times
    for i in range(0,10):
        pyautogui.press('enter')

#Calling the website and pressing 10 times in the same time
thread2 = Thread(target = threaded_function2)
thread2.start()

thread = Thread(target = threaded_function)
thread.start()

If still actual, I had same issue on Mac, and solution was simple:

• for chrome is set AutoSelectCertificateForUrls policy like that:

  defaults write com.google.Chrome AutoSelectCertificateForUrls -array-add -string '{"pattern":"[*.]example.com","filter":{"ISSUER":{"CN":"**cert issuer**"}, "SUBJECT":{"CN": "**cert name**"}}}'
  

• for safari:

  security set-identity-preference -c "**cert name**" -s "**example.com**"
  

then use it in code like subprocess.call() in python
