Instructions: eduroam for macOS
Download the installation profile for macOS from cat.eduroam.org.
If you do not see the profile automatically, find the profiles in System Preferences and click Downloaded Profile
Tap Install in the top right corner
While installing, you are changing the system settings, so you might be asked to enter the administrator password.
Installation is finished. If your login data is correct and you are within the eduroam network reach, you will be connected in a while.
The eduroam network is protected by a firewall, but it is still very important to secure your own computer with a firewall as well.
