    Installing the Postgres PostGIS extension on OSX

For reference: http://postgis.net/install
If you don’t already have PG installed

The most reliable way to get PostGIS on OSX is to download and install Postgres.app. Great for development and testing. Do not mix with other installations.  Select the extension when prompted.
