Does Psychopy work on mac M2? I have been using psychopy for years and just got a new macbook air, downloaded the new version of psychopy, and can’t get anything to run

OS (e.g. Win10): Mac M2 Ventura
PsychoPy version (e.g. 1.84.x): 2023.2.2
Standard Standalone? (y/n) If not then what?: y
What are you trying to achieve?:
Running a demo

What specifically went wrong when you tried that?:
ioHub Server Process Completed With Code: Negsignal.SIGSEGV

Hello,

I suspect this is an issue with PsychoPy not having permission to control the screen. You can switch ioHub to PsychoToolbox or system preferences → security → input monitoring → add psychopy. Would also add it to security → accessibility.

thanks! Went through the various fixes there and in the end switching ioHub to psychtoolbox worked.
