Hello! I’ve been having an issue with PsychoPy’s coder view, since it won’t let me open up the “editor” panel, only the “output” and “source assistant” panels. I’m currently using a MacBook Pro with an M2 chip, and I’m on Tahoe 26.5 with PsychoPy v2026.1.3. I’ve tried other standard fixes but nothing has helped. Does anyone know how to fix this issue so that I can edit my code within PsychoPy standalone?
Delete appdata.cfg
For a PsychoPy issue like this, I’d also check whether the Coder layout got saved with a corrupted panel configuration. Renaming or removing appData.cfg (as mentioned above) is usually the first thing I try, since it forces PsychoPy to rebuild the UI layout from scratch. If that doesn’t help, try launching PsychoPy with a fresh user profile to rule out a preferences-related problem rather than a macOS or M2 compatibility issue. See Cleaning preferences and app data for the official PsychoPy guidance on resetting app data and preferences.
