title: PyInstaller App not opening on Mac
body: <p>I'm trying to create an app for a program I have written. I have no problems doing it on Windows, but I've been trying for a week to get an OSX version working. Here is what my terminal looks like:</p>
  
  <pre><code>Thomass-iMac:gene_expression Tomallama$ python3 --version

  <p>Then, when I go into the dist folder and run the app this is what happens.</p>

  <p>Like I said, this process works just find when I run it on Windows. But I can't figure out the reason for it not working on Mac. I also need to keep it using Python 3.6 because there are f-strings in the code.</p>
