PsychoPy won't open in mac os mojave

OS (e.g. Win10): macOS mojave 10.14
PsychoPy version (e.g. 1.84.x): 1.84.2
Standard Standalone? (y/n): y


I updated my operating system to Mojave and recently I realized that I cannot open PsychoPy program (error window provides open console or terminate options) nor any psyexp files from earlier.

Would upgrading PsychoPy solve the issue? Or is there a better solution?



Try maybe updating PsychoPy to 1.90.3? I’m using 1.90.3 without a problem so far with Mojave and I know it is a more stable version than 1.84.2.


Thank you for the suggestion. I downloaded standalone version 1.90.1 but unfortunately I still have the same problems.


Hi, you can read this link. Psychopy1.90.3(or Psychopy3.0) cannot open on the mac OS Mojave

I believe this is fixed in PsychoPy 3.0.0b12

version 3.0.0b12 works, thank you all…
