Running app.py from the auto-instrumentation exercise doesn't run on a MAC. Port 5000 is already taken by a system process #8
Description
As described in the title, I was not able to run the Lesson 6 Lab, exercise 1 (Instrumentation of the Python (Flask) Component (1)).
The reason seems to be that a system process already takes the default port 5000.
Workaround: change the port to anything not used yet.
Changes I made to file automatic-instrumentation/todoui-flask/app.py:
# ...
if __name__ == '__main__':
app.run(host='0.0.0.0', port=5002)
# app.run(debug=True) # doesn't work with auto instrumentation

Oh, I didn't encounter the problem on my M2 Mac. Thanks for the hint. An alternative approach is to disable AirDrop

Ran into same issue on my Intel MacBook Pro. Disabling AirDrop as per @JenSeReal 's suggestion helped to get back into the lesson.
