I just installed SageMath 9.2 on a new Mac. It does not launch Jupiter either via the App or via terminal launch. It states there is a "ModuleNotFoundError: No module named '_ssl' " error as discussed below, but I am not sure the cause. I have applied the other recommendations listed via other posts.
Below is what happens at via the command line launch. Any suggestions? When I try yo rebuild Python (run "sage -f python3") it gets an error with SciPy installation.
Thank you

The Jupyter notebook requires ssl, even if you do not use https. Install the openssl development packages in your system and then rebuild Python (sage -f python3).
