#ATTENTION!: use interactive python run single step and open another terminal using ps command check whether process behave as u expect
#           use sleep command if u can't catch what is going on
#TAKE OUT:
#1. u can't use exist chrome binary under /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome run as chromdriver
#   like this: browser = webdriver.Chrome(executable_path="/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome")
#   the binary under /Contents/MacOS is different from chromedriver binary, 
#   so you have to have a chromedriver
#2. u also need a real Chrome as well, you don't need to specify its as binary_location, but you do need one. you can move google chrome from /Applicatin to somewherelse 
#   to test it and then move it back
#3. to make it script find executable chromedriver, you either specify it using executable_path arguement or include parent folder of chromedriver(binary) to PATH env
#   or similarly just move chromedriver to some path already in PATH, for me I move it to /user/local/bin
#4. though it is weird to have to MB large file under /usr/local/bin, instead you could install chromedriver via brew, then you only have symlink under /user/local/bin
