I am attempting to use
OpenCPN on my M1 MacMini. I am able to download and install the program, the
charts, and the plug-ins.
But despite numerous downloads, I cannot get any chart detail to display. All I can display is a rough, two-color, representation but no useful detail. So, for example, the
Texas Gulf Coast consists of a series of short line segments that trace the rough
arc of the coast. Galveston bay looks like a triangle in the coast. Zooming in does not open any detail whatsoever.
Any clues how to solve this issue?
