Please fix the issue with finding Python on MacOS in V8

[TrongHieu90]

By default, Homebrew will install python 3.11 to this path:

Primary Path for the Executable
The main directory containing the python3.11 executable, as well as symlinks for python, python3, pip, and pip3 (if configured), is:

Apple Silicon (M1/M2/M3 Macs): /opt/homebrew/opt/python@3.11/libexec/bin
Intel Macs (default path): /usr/local/opt/python@3.11/libexec/bin

The code right now will always check incorrect homebrew Python path or for system Python (which comes with Xcode Tools with version 3.9.6). And it is in Unity package so I cannot modify it.

Or maybe support custom path by user's input.

Hi @TrongHieu90, I assume you're talking about the setup popup. What version of the app you're running?

Similar here on MacOS using pyenv to manage Python. Setup Window says python not found in PATH (attached).

~/.zshrc contains:

# brew install pyenv pyenv-virtualenv
export PATH="$HOME/.pyenv/bin:$PATH"
export PATH="$HOME/.pyenv/shims:$PATH"

Running in Terminal:

> which python
~/.pyenv/shims/python

python3 is at /usr/bin/python3 (I think by default on a Mac), so it looks like this should find it 🤔

UPDATED: I think I see the issue, unity-mcp checks for python >=3.10, the MacOS default (and what I had via pyenv) is ~3.9.6.

Apologies, the README does state v3.10 is needed. I wonder if Setup Window could say "version REQUIRED_VERSION not found".

@TrongHieu90 I'm primarily on apple silicon and it works for my homebrew installation. An option for users to enter their path isn't a bad idea. But confirm your version first, the older versions notoriously had lots of errors.

Thanks @richardleggett , and not a bad suggestion as well

Im using latest v8 version. The code that searches for the homebrew python path is not correct (opt/homebrew/bin) Maybe it was the old default path. Homebrew installs python to the path in the image, then the code will check for system python (which is 3.9.6 that comes prebuilt with Xcode Tools)

This is the break point info. The common locations should be a settings that user can edit

Good feedback

Just to be clear, even if the setup window is incorrect, rest assured that you can still use it. But we'll fix it
