For some, it is easy to install QGIS and if you normally find installing and managing software easy just go to https://www.qgis.org, Now click the big green download now button.

Since installing QGIS sometimes is a bit tricky This page has four sections

For Windows users

If you just want a quick look at QGIS I recommend using the standalone installer for the QGIS chose the “Latest release (richest on features)” (the blue one). If you are going to use QGIS for a semester or longer I recommend using the QGIS in OSGeo4W (recommended for regular users) (the red one). It is a bit more complex to install but you typically get a more stable and easier to update the software this way.

When the installer asks what to install chose all but QGIS LTR

For mac users

If you have a mac that has not been updated for years, it might be a good idea to do so now. If haven’t updated your Mac for years and it is running an OS version lower than High Sierra (10.13) you must update or use the cloud computers (on a mac you can see the OS version by clicking the apple in the top left corner of the screen and “About this mac” or something similar in your language.

My mac is MacOs 12.5.1 so I’m good to go

Like for windows, there are different installers to choose form I recommend the Official All-in-one, signed installer of the latest release (The red box on the image below, the version number can be different from on the image)

If you experience problems

Sometimes it is just not that easy so here is a detailed set of screenshots to guide you through the installer process.

Windows

Chose the red installation (recommended for semester use)

Click the installer link and when it has been downloaded run the program

Choose express installation

Chose httos://download.osgeo.org

Chose QGIS, DGAL and GRASS

Accept the additional dependencies

There are several to accept, the installer now starts running and the installation when the bottom green bar (Disk) reaches the end.

The qgis app is now installed and is placed in the OSGeo4W folder in the start menu. To launch QGIS chose “QGIS Desktop XXX”

For Mac users

After choosing Official All-in-one, signed installer of the latest release (The red box on the image below, the version number can be different from on the image)

Your Download folder should now continue the file “qgis-macos-pr.dmg” and run the installer by double-clicking it. After verifying it (Can take some time)

You should see the first screen of the installer

After reading and agreeing to the licence agreement (click Agree). The installer will show a window saying Opening “qgis-macos-pr.dmg”, this takes some time. When finished drag the QGIS icon to the application folder in the window.

You will now see a new windows saying preparing to copy to “Applications”. this can take some time. Open your application folder and locate the QGIS app. When the little piechart is full and QGIS no longer grey you can launch the app.

However, if you just double-click the app you will get a pop-up saying that QGIS cannot be opened.

click cancel and open QGIS by right-clicking on the app and choosing open.

You will now get a new pop-up from which you can chose “Open”

From now on you can launch QGIS from your application folder or launchpad just like any other program.
