Release 2020.2.3 fixing launch issues for macOS Catalina/Mojave

Announcements
#1

Hi folks, I’ve spent most of this week battling with Apple’s “Gatekeeper”. This used to be a relatively minor annoyance - it used to complain that we weren’t a known developer so you’d have to agree to the app running.

Then in Catalina it got worse and the app would appear to start but then crash with no information (but it was actually the Gatekeeper jus tbeing more annoying).

Well, happily after a week of battling I believe we won!! PsychoPy 2020.2.3 is now fully signed by us at Open Science Tools Limited and, although it asks about providing access to your files, it does run and no longer needs you to visit security panels to agree. Woop woop!! :rocket:

Thanks!

Is there a plan to make PsychoPy compatible with MacOS 11 (Big Sur)? Currently, it crashes due to a failure to load OpenGL framework.

Thanks very much!

Eek, I hadn’t looked at this but if macOS 11 is dropping support for OpenGL then we’ve got something of a problem! Rewriting all the rendering calls would be a big task. Doing it just for one OS, especially when we know the timing is less good there, is something we’d have to think about carefully. I’m not sure it’s worth the staff time given the limited staff that we have and other priorities.

#6

Thanks Jon!

I agree that it takes too much effort to re-write low-level drivers just for one platform.

Back to the issue, macOS 11 actually doesn’t drop OpenGL at all, just not supporting the latest version. In my case, I can still see the library in the location (/System/Library/Frameworks/OpenGL.framework) that PsychoPy claims “can’t find”. I haven’t done comparison between macOS 11 and macOS 10.15 in terms of the difference in OpenGL library. But the existence of OpenGL library suggests that there might be some easy to fix issue in the current code.

People will move on to macOS 11 sooner or later, especially for those buying a Mac after this fall. macOS 11 would be their only option by then.

Thanks so much for your time!

Ah, OK, glad they haven’t dropped support altogether then (I believe that is on the cards for one day, because they want people to use Metal instead). The import error you’re seeing is from Pyglet (the lib we use to provide opengl access) not from PsychoPy itself. It might be that newer versions of pyglet will/do handle this seamlessly and we won’t need to worry about it.

Also, there’s the other backend (GLFW). Would be interested to know what happens if you simply switch to wintype=‘glfw’ backend in the Window?

#8

Thanks Jon!

Because I couldn’t open PsychoPy UI at all, I cannot set winType. Is there other ways to change the setting by modifying certain file?

#9

Ah, that’s annoying - so you can’t do from pyglet.window import keys! We can prevent importing of pyglet being a requirement in the next release but for now i think you’ll be able to tweak as follows:

Fetch your open copy of pyglet/window/key.py:
https://github.com/pyglet/pyglet/blob/pyglet-1.5-maintenance/pyglet/window/key.py and save it inside psychopy/app/builder/

Then change psychopy/app/builder/validators.py around line 27 from

from pyglet.window import key

to

try:
    from pyglet.window import key
except Exception:
    from . import key

Hopefully then you can launch the app

#10

It works! Thanks so much, Jon!

I don’t have time to test functions other than launching the app on macOS 11. Will report other issues if I encounter in the future.

#11

Hi Jon - sorry to contribute further rain on your parade, I’m also not able to launch 2020.2.3 in 10.12.6, and weirdly I also seem to have broken my ability to launch previous versions.

Error from console here when launching app version. Judging from what you’ve said, I suspect the first is the smoking gun. I’ve also tried to install using pip and have had the same fail on launch.

I don’t think that its related but I’m still experiencing internal errors when I try to run the experiment with a warning that says (the content of the message vary but it always says internal error and advises me to send on an error report to developers):

Hi Lucy,

This is one bug we missed, a few people have spotted it! I’ve pushed a bug fix to the next release, in the meantime here is a solution from another thread which will fix it for you in the short term:

Thanks very much. Are “unhandled internal errors” bugs then? I feel it would help my understanding as I have ran into a few.

#15

With the popup box you mean? Yes, these only happen when something has gone wrong with the program.
