Just recently I saw an error in the forum related to MacOS catalina public beta. The issue is that MacOS will not execute the python script due to python not being notarized for Catalina. I’m assuming python will notarize it before the final release but in the meantime this is how you fix it.
It seems that with Catalina Apple got picky and doesn’t allow turning off Gatekeeper directly.
Open a terminal and run:
sudo spctl --master-disable
It will request your password.
Then go into your System Preferences -> Security and a new option for running apps will be there waiting for you.
@JonL, thanks for this post. I am not part of the beta program with Apple, but I did get notified that Catalina was available for me to download last night so I took the plunge and did it! After several hours (sigh) it was finally installed and ready to use!
This helped me out in terms of getting rid of that error.
I wish some of my other programs were that easy to fix. You should have seen the look on my face when Final Cut Pro said it was not able to run on Catalina and then the App Store saying it was not able to update Final Cut Pro because it was already installed, LOL. I did get it fixed, though.
but it did sound good! Ah well Apple auto correct
