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 so much for the commitment and speedy fix Jon! Amazing stuff!

Thanks so much Jon for the rapid fix. PsychoPy 2020.2.8 seems to be running just fine on my MacBook Pro 16" with Big Sur.

Just wanted to echo my sincere thanks for the speedy changes, Jon! I am extremely grateful (as are my graduate students).

Eek. So I have some people doing a longitudinal training study (which is covering a significant period of time) that I created in PsychoPy v1.90.2. Someone’s just updated their OS to Big Sur and they’re now receiving the following error message:

Traceback (most recent call last):

As mentioned in the thread above, the issue seems to be with Pyglet and OpenGL. Can anyone recommend a potential way to fix this in such an old version of PsychoPy?

Help much appreciated!

Looking at this from a PsychoPY 1.90.2 perspective: https://github.com/psychopy/psychopy/pull/3309/commits/f0d3533e19b5f03d4b7a93e79ecd87b5b392750d

I can find (both attached):

/Applications/PsychoPy2.app/Contents/Resources/lib/python2.7/psychopy/visual/init.py
/Applications/PsychoPy2.app/Contents/Resources/lib/python2.7/psychopy/visual/textbox/fontmanager.py

But I’m not sure what the equivalent file for ‘visual/textbox2/textbox2.py’ would be? The textbox folder (there isn’t a textbox2 folder) contains only:

init.py
init.pyc
pycache
fontmanager.py
fontmanager.pyc
freetype_bf
parsedtext.py
parsedtext.pyc
textgrid.py
textgrid.pyc
textureatlas.py
textureatlas.pyc
TODO.txt

psychopy/visual/init.py has very similar code to that in Jon’s example, whereas
visual/textbox/fontmanager.py is quite different:

import math
import numpy as np
import unicodedata as ud
from matplotlib import font_manager
from psychopy.core import getTime
from .textureatlas import TextureAtlas
from pyglet.gl import (glGenLists, glNewList, GL_COMPILE, GL_QUADS,
glBegin, glTexCoord2f, glVertex2f, glEnd, glDeleteLists,
glEndList, glTranslatef, glDeleteTextures)

What edits would you suggest I make?fontmanager.py (18.9 KB) init.py|attachment (2.7 KB)

Just to add to this… I know that in general it’s preferred if people continually update their code to the most recent version of PsychoPy, but at the time I wrote it my code worked best in 1.90.2 (which is to say that it didn’t run at all in 1.90.3) so I stuck with it. It’s a several month-long training scheme, with several twists and turns, so not the simplest thing to just update (well, not for me anyway). By this point I’ve had participants taking the training for my experiment for a great deal of time using their own downloaded copies of 1.90.2, so it’s neither easy nor practical for me to have to update the whole lot (although rest assured, I’d write any future experiments in the most up-to-date PsychoPy version). As such, some thoughts on how to save it from the perils of Big Sur would be greatly appreciated if at all possible… thanks :slight_smile:

Hi @Jon
Just downloaded the 2020.2.10 release standalone and installed on my Mac with Big Sur 11.1
Alas, it does not start and shows a PsychoPy error instead.
Any more leads on this?
Thanks!

shows a PsychoPy error instead.

Error messages contain text that is essential to working out what’s going on. If you don’t tell us what the error message was (all of it) then we really can’t help


That’s literally all.
Nothing in the console then either

OK, thanks. That’s not very helpful of Big Sur then! :wink:
I wonder if any useful information was stored in the log file. Could you go to a terminal window and run:

cat ~/.psychopy3/last_app_load.log

Maybe that will give us some clues. Otherwise I’m at a loss how to help right now

Thanks @Jon. I’m struggling a bit. When I open a Terminal and copy and paste the command I get " No such file or directory" I then tried a few things including to navigate to the top level and into the Applications directory where PsychoPy3.app lives. I also changed the spelling from psychopy3 to PsychoPy3 but I always get the same error/
Sorry, I am not too familiar with terminal so I’m probably missing something trivial.
Can you suggest what else I could try to make the command work?

~ is your user folder (also called your home folder). If you are more comfortable using the Mac Finder than the Terminal, then select “Home” from the “Go” menu. Push CMD + SHIFT + . to see invisible files (files or folders that start with a . are normally invisible). At the top level of your user folder, you should now see a folder called .psychopy3, which should contain that log file.


Looks like there is no log file – which is why the terminal couldn’t find it I guess…
Any other ideas what I could do?
