I've tried with additional backends: WX, WXAgg, WXCairo, Qt5Agg (in matplotlib speak).

With these, I can at least import matplotlib.pyplot, but as soon as say matplotlib.pyplot.plot is called and the backend is loaded, the code breaks (error message for WXAgg below). Is multiprocessing in an interactive shell simply not meant to be supported on MacOS?

Error in atexit._run_exitfuncs:
Traceback (most recent call last):
