OS: mac OS Mojave 10.14.1 (18B75)
Psychopy version: Psychopy1.90.3(or Psychopy3.0 11b)

Hi everyone,

Yesterday, I updated my mac OS to Mojave. Today, I found I cannot open the psychopy1.90.3(or Psychopy3.0). After opening, the result was shown in the picture.

Could anyone give some suggestions how to deal with this problem.

Ah, OK, I can see where this problem is coming from now (and why it didn’t affect me on my own Mojave machine). Try installing git on your computer. https://git-scm.com/

Explanation: we use an application called git to switch between versions of PsychoPy at run-time. We check if this is installed first, but it seems that the process of checking is no longer working under Mojave. The result is that PsychoPy thinks git is installed and proceeds to try and use it but falls over.

Thanks for getting a full error message to us. That will help us fix the issue more gracefully.

And do let me know if there are further problems after git is installed

Hi, @jon, thanks for your quickly reply. Later, i tried to open the Xcode(older version 8.0) app on the Mojave OS according the error hint, and i found the Xcode app was also cannot open. So i reinstalled the latest version of Xcode(10.0). After that i can open the Psychopy software smoothly. Maybe the git was also installed accompany the installing of Xcode app?
Anyway, thank you so much.

Yes, installing XCode is one way to install git
