I recently updated to macOS Catalina (Version 10.15.5) and have found that PsychoPy (2020.1.3) no longer opens the .psydat files. When I double click the file, I receive the Finder message: " There is no application set to open the document “_GIL_Experiment_Part1_C1_Updated_Version_2020_Jun_10_0736.psydat”.". When I go to choose an application to open it, PsychoPy is greyed out, and when I select it and then click “open”, PsychoPy starts up and then goes to its blank default file instead.
What would you suggest?
