Dear Lyle,

hopefully this will bring you further (I am not using a Mac - I just
assume it's the same like on a linux-box).

1. Open a terminal and launch grass in text-mode with "grass63 -text"

2. Name your LOCATION (e.g. "xy"), leave for the start the Mapset set to
PERMANENT and provide the path to where you want the LOCATION to be
created (that should be your GIS database). Finally hit "Esc+Enter".

3. Read the questions and answer (...yes in the first 2, choose "A",
confirm with yes, provide a description if you want, confirm)

4. Here you can ignore the settings about the extent of your location
and continue till you finally get into your GRASS session in your new
"xy" location.

5. Import your raster map with r.in.gdal and your shapefile with the
v.in.ogr module(s). Make sure to use the "-e" flag so the computational
region extents to the extent of your shapefile.

(example: v.in.ogr -e dsn=CORNELIUS_ddpolygons_None.shp

*** If you would like to do that with the GUI type "gis.m" immediately
after you enter the "xy"location and look for the respective import
tools under File > Import raster (vector) map ***
