[Mne_analysis] Plotting delay pyvista Mac M1

Hum. Ok so you managed to install pyvista, as your first email
actually implies (sorry my bad).
Could it be an issue with the the matplotlib backend used?
I remember vaguely that specifying the matplotlib backend could make a
difference when opening IPython, e.g.,  ipython --matplotlib tk
