Install Python (Anaconda is easiest)

As explained here: https://pythongisandstuff.wordpress.com/2016/04/13/installing-gdal-ogr-for-python-on-windows/, 
download the compiled GDAL from here: http://www.lfd.uci.edu/~gohlke/pythonlibs/#gdal

Then:
$ pip install GDAL-blah-blah.whl

If fiona (https://github.com/Toblerity/Fiona) is required, download it from http://www.lfd.uci.edu/~gohlke/pythonlibs/#fiona and install it the same way.

Launching iTerm2 from macOS Finder

(Based on info from Peter Downs' gitub but with modified behavior to open a new terminal window for each invocation instead of reusing an already open window.)

The following three ways to launch an iTerm2 window from Finder have been tested on iTerm2 version 3+ running on macOS Mojave+.
