Hi @f-riente, I am afraid that for the Tobii 4C and ET5 eye trackers in both the Stream Engine and Interaction Library only Microsoft Windows is currently supported.
If you want to develop a product integrating Tobii Eye Tracking we have other solutions such as the Tobii Eye Tracker 4L, and integration platforms that also support Linux and MacOS. If you are interested in integrating eye tracking in your product please Contact Tobii @ https://tech.tobii.com/contact/
