My system version is mac os 11.0.1, when I open psychopy, I encountered this error, I can’t open it.

Traceback (most recent call last):
File „/Applications/PsychoPy.app/Contents/Resources/lib/python3.6/pyglet/init.py“, line 378, in getattr
AttributeError: ‚NoneType‘ object has no attribute ‚_create_shadow_window‘

During handling of the above exception, another exception occurred:

PsychoPy is not currently working on Big Sur (Mac OS 11). There are a few other posts about this. There is a way to bypass this error, which allows you to code in PsychoPy and sync online to run JS, but as of right now there is no known way to run experiments locally on Big Sur.

See here: Psychopy on Big Sur on mac

It ended up being called 2020.2.8 after a last minute bug in 2020.2.7! But I think this should fix the Big Sur troubles:

Thank you jon – for everything you and your team are doing, especially on such short notice for mac users!
