Installing on macOS

Installing the software on macOS could be the most complicated of all (because of GRASS). However, thanks to William Kyngesburye, the compiled version of QGIS already contains a copy of GRASS along with other GIS software used by QGIS. In order to install QGIS, we have to download the disk image from http://www.kyngchaos.com/software/qgis.

If you need the GIS software on OS X 10.6 or older, take a look at Kyngesburye's archive at http://www.kyngchaos.com/software/archive. Before installing the software, make sure you read his hints and warnings related to the given image.

PostgreSQL and PostGIS are also available from the same site, you will see the link on the left sidebar. pgAdmin, on the other hand, is available from another source: https://www.pgadmin.org/download/pgadmin-4-macos/. Finally, the GeoServer macOS image can be downloaded from http://geoserver.org/release/stable/, while its dependency of Java 8 can be downloaded from https://www.java.com/en/download/.

If you would like to use pgAdmin 3 instead, or pgAdmin 4 is not supported by your OS, you can download pgAdmin 3 from https://www.pgadmin.org/download/pgadmin-3-macos/.

The only thing left is configuring the QGIS Server. As the OS X and macOS operating systems are shipped with an Apache web server, we don't have to install it. However, we have to make some configurations manually due to the lack of the FastCGI Apache module, on which QGIS Server relies. This configuration can be made based on the official guide at http://hub.qgis.org/projects/quantum-gis/wiki/QGIS_Server_Tutorial.
