Installing Instapy Quickstart Master on Mac - Issue - Please Help

Hello,

I have a problem for installing : Instapy Quickstart Master on Mac.

I downloaded the file on my Mac, got google chrome as a default browser and I dowloaded the last version of Python for Mac ( 3.11.4).

I am now trying to install the " instapy QuickStart master" and I am getting the following message from my terminal.

/Users/guillaumebenoit/Desktop/instapy-quickstart-master/installation/MacOs/install.command ; exit;
guillaumebenoit@MacBook-Pro-de-Guillaume ~ % /Users/guillaumebenoit/Desktop/instapy-quickstart-master/installation/MacOs/install.command ; exit;

**Please install the latest version of Python from https://www.python.org/downloads/**
-> The one I got is the last version ...
