Have just downloaded PsychoPy3 and it crashes immediately after opening. Can’t even read the text box before it crashes. I’m trying to run it in a macOS High Sierra 10.13.6 and also have PsychoPy2 running perfectly in the same notebook. Any suggestion?
I think it’s a problem that they are working on. I’ve experienced the same problem.
You can try starting Py3 via terminal.
-Right click on PsychoPy3 icon in the app folder
-Show content
-Contents
-MacOs
-PsychoPy3 (the one with terminal icon)
That should work for you while they are fixing the problem.
(Starting Py3 via terminal) Does it crashes or freezes?
If it freezes, take a look at the terminal, it probably ask you to insert your username and password. That should make Py3 stop freezing.
If it just crashes, I think it’s best to wait until they fix the problem.
