How to install QGIS for macos

QGIS is a program that you download onto your computer, which can be used to perform spatial operations (analyze and manipulate your data), and make composite maps.

For the Digital Humanities Research Institute, we use QGIS because it is free and open source, compared to many other tools available for macOS and Windows users.

Step 1: Download

Download the latest version of QGIS from the QGIS download page

Step 4: Open the QGIS Application

Start by navigate to your Applications folder and double-click on QGIS. You will likely receive an error that says “QGIS can’t be opened because Apple cannot check it for malicious software.” To solve this, go back to your applications and this time instead of double-clicking on the QGIS app, right-click and select “Open.” Then when prompted again, select “Open.” From this point onward, you will not have to go through allowing the software to run every time. You will simply be able to open the app by double-clicking on it.

Launch QGIS. A new project will look like this:
