I am running the latest version of Engine on an up to date M1 Mac Mini and I’m using a Logitech MX Master 3 Mouse. I am not interested in your opinions on Logitech at all. What I’m interested in is filing a bug report with the Engine OS software. I’m having the exact same issue as the person in the thread, the scroll wheel does not work unless I enable the scroll bar. My mouse works in literally every other application as expected. It is only EngineOS that does this.
