We have a private python plugin that uses Shapely to do some processing. I finally uninstalled QGIS 2 from our company machines and it broke the plugin as Shapely could no longer find GEOS, as removing QGIS 2 removed the /Library/Frameworks/GEOS.framework copy of GEOS.

QGIS 3 seeks first to load GEOS for use in Shapely from /Applications/QGIS3.14.app/Contents/Frameworks/Python.framework/Versions/Current/lib/libgeos_c.dylib but cannot find it, so tries to fallback to /Library/Frameworks. I have worked-around the issue by pushing out GEOS as a separate package installed in /Library/Frameworks, but I assume that it should be finding the built-in copy of GEOS to prevent version issues.

Stacktrace:

Couldn't load plugin 'ArkSpatial' 

OSError: Could not find lib geos_c or load any of its variants ['/Applications/QGIS3.14.app/Contents/Frameworks/Python.framework/Versions/Current/lib/libgeos_c.dylib', '/Library/Frameworks/GEOS.framework/Versions/Current/GEOS', '/opt/local/lib/libgeos_c.dylib'].
