PsychHID-ERROR: One reason could be that some HID devices are already exclusively claimed by some 3rd party device drivers
PsychHID-ERROR: or applications. I will now retry to only claim control of a hopefully safe subset of devices like standard
PsychHID-ERROR: keyboards, mice, gamepads and supported USB-DAQ devices and other vendor defined devices and hope this goes better…
PsychHID-INFO: That worked. A subset of regular mouse, keyboard etc. input devices and maybe some vendor defined devices will be available at least.

Hi There,

This looks like an issue with the event module not being defined. I have something seen this in worshops for mac users that need to give psychopy permissions in the system preferences - please could you check in your system prefs if there are any notifications on giving psychopy access?

Thanks,
Becca

thank you so much!

my laptop was set so that psychopy couldn’t monitor input from my keyboard.

can’t thank you enough,
Hallie.

I started experiencing the same problem today, and there was no mention in my System Preferences (Security & Privacy) of Psychopy having asked for permission to access anything.

However restarting my Mac made the problem go away. Perhaps some other app had requested access to the keyboard, but then hadn’t;t relinquished it when it quit?
