    trained_face_data = cv2.CascadeClassifier('haarcascade_frontalface_default.xml')
 
  
    webcam = cv2.VideoCapture(0)
    
    
    ret, frame = webcam.read()
   
   
    grayscaled_img = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
    
    cv2.imshow('image face detector', grayscaled_img)
    
    cv2.waitKey(1)

Answer 1

Solved just have to change the parameters cv2.VideoCapture(0) to cv2.VideoCapture(2)

hope that can helps other Mac users
