Installing Python and Jupyter on fresh macOS multiple prompts

[rebornix]

On a freshly installed macOS, the very moment we install Python and Jupyter extension per kernel source suggestion (Select Kernel -> Install Recommended Extensions), I got a prompt from the system and an error notification from Jupyter

• Error from Python extension saying it's not recommended to use
• Prompt from macOS, it's probably triggered by the access of Python interpreter

Not sure who is initiating the Python environment access so let's start the investigation from here. If it's not recommended to use the default Python on macOS, I expect not to see any prompt from system or Python extension.

Clicking on Select Interpreter shows a quick pick, which tells me there is Python is not installed

Picking the option opens the walkthrough, which suggests to brew install, and it fails as I don't have brew yet.

@rebornix please could you file issues related to python extension in their repo
Eg the walk through and interpreter picker is clearly on issue in python extension

@rebornix

please could you share the debug logs with the latest insider release and pre/release

This is a bug, can be fixed.

Prompt from macOS, it's probably triggered by the access of Python interpreter

It happens when extension attempts to check whether usr/bin/python is a valid interpreter or not by running the file, so not sure what we can do there. Once Jupyter handles microsoft/vscode-jupyter#12719 which ensures discovery no longer happens at startup, the prompt should start appearing.

Picking the option opens the walkthrough, which suggests to brew install, and it fails as I don't have brew yet.

We can recommend python.org in the text stating to use that if brew is not installed.
