Unable to use "ctrl + c" to close a port used for visualization opened through python MESA on Mac OS

Question

This is the code I am using to run a visualization using python MESA. However, as per the tutorial, I should be able to stop the vizualization window using "ctrl + c" in the terminal but that dosen't work.

This is a snip of the vizualization opened on safari.

Link to the tutorial: https://mesa.readthedocs.io/en/stable/tutorials/adv_tutorial.html

This image shows the instructions.

I have tried the following: lsof -i : 8521 kill -9 PID #

But this dosen't work.

I also tried "ctrl + ." and it restarts the kernal but dosen't close the port and the vizualization.

Answer 1

"ctrl + ." restarts the kernel but doesn't close the visualization. I tried to close the visualization manually and run the code again and it worked!
