This script works on macOS.

• Use python 3
• The following packages are required:
• pip3 install requests
• Run python3 check_ge_appt_schedule.py on a terminal
• When there is new slot available, it shows the notification on the macOS with a human voice prompt
• Appointments run out very quickly- on an average 10s window
  • Make sure you keep the browser window for TTP logged in and schedule it asap
