I'm trying to upgrade to the newest version of qGIS but get the following error message when I open the installer:
QGIS requires the GEOS framework version 3.4 or newer.
I've had no luck maintaining my version of geos via the geos download page, and have instead installed it via homebrew. Is it possible to tell qGIS where the homebrew maintained version of GEOS lives?
I would maintain osgeo via https://libgeos.org/ but keep getting error messages when I run the newest installer (3.4.2) and all advice I've found elsewhere on debugging the installer suggest that I shouldn't bother messing around w/ all the dependencies and should instead use homebrew.
So this brings me back to where I started: is it possible to have homebrew maintain a version of osgeo that qgis can continue to locate? Or, am I forced to keep trying to debug the geos installer?

The easiest way to upgrade is to use the binaries at http://www.kyngchaos.com/software/qgis
