Thanks, Eugen. Actually I tried that last year. Although I got no error messages during the installation process, when I attempt to launch nanovna-saver I receive the following:
Larrys-Little-Box:nanovna-saver Larry$ python3 nanovna-saver.py
Traceback (most recent call last):

From the error, I suspect it's because I'm still on Mac OS X 10.10. Upgrading to OS X 10.14 is on my to-do list. I've been postponing it because my favorite SDR software, SDRDX, does funky things on OS X 10.12 and up. Almost ready to take the plunge, though.
