Link to the most relevant existing thread you have found: Key press not working on MacOS (didn’t work for me)
What specifically went wrong when you tried that?:
Nothing changed
Hello! I have suddenly developed an issue where PsychoPy doesn’t see my keypresses, including ESC, so I have to force quit the application every time I try to run the experiment. My experiment was made in Builder and it ran perfectly fine just before the weekend. This may be related to me updating PsychoPy to the newest standalone version (2026.1.3), although I have tried deleting it, installing a previous version that ran fine, and the issue persists.
I have checked my privacy settings, and PsychoPy is turned on both in Input Monitoring and in Accessibility. I have also tried changing the backend from Psychtoolbox to Pyglet and to the other option that’s on there - no change.
The only thing that works is to leave the “allowed keys” bit in the Keyboard property empty to allow all keys. However, that doesn’t work for my experiment and I would like to be able to allow only certain keys.
Additionally, the keypress does work when I run the experiment in browser mode. However, I need it to run in both modes.
Will be very grateful for any suggestions and advice.
