Hi @sotiri, using my old Mac that could reproduce the button click not responding issue, I think the problem has to do with mouse position not being detected (on my machine, it was safari only, but for two subjects, it was chrome on Mac). When logging the mouse position, no matter how I move it, it was always (-1.2,0.5) and therefore no contain/press method could work. I am using height units, so boundaries are (+/-0.8,+/-0.5) for a screen ratio of 16:10, right? Any ideas why the mouse position is set to be outside of the screen? A similar issue was reported [here](https://discourse.psychopy.org/t/constant-mouse-position-on-safari-macos-when-calling-getpos-on-a-mouse-component-repeatedly/8883).

EDIT: I’ve seen some old posts discussing that this might be related to Retina display?
