Python3 issue with current build on Apple Silicon Mac

[redconfetti]

I tried to start up the latest build for Mac after installing Python3. The log reports:

15:10:00: warning Couldn't find a Python 3.10 installation. Please install using Homebrew (brew install python3), MacPorts (sudo port install python310) or from https://www.python.org/ftp/python/. Turning off all adaptations.

I see in GenericAdaptation.cpp it is looking for a path present for Python v3.10

I tried to install this version explicitly and the path is /opt/homebrew/opt/python\@3.10/Frameworks/Python.framework/Versions/3.10/.

$ brew reinstall python@3.10
$ ls /opt/homebrew/opt/python3/Frameworks/Python.framework/Versions/3.10
ls: /opt/homebrew/opt/python3/Frameworks/Python.framework/Versions/3.10: No such file or directory
$ ls /opt/homebrew/opt/python\@3.10/Frameworks/Python.framework/Versions/3.10/
Headers		Python		Resources	_CodeSignature	bin		include		lib		share

I uninstalled this and installed the 'python3' package, which installs under /opt/homebrew/opt/python3/Frameworks/Python.framework/Versions/3.12/

$ brew install python3
$ ls /opt/homebrew/opt/python3/Frameworks/Python.framework/Versions/3.12/
Headers		Python		Resources	_CodeSignature	bin		include		lib		share

Additionally I get a crash report each time I close the application. I can provide the full report to you if needed.

I installed Python 3.10rc2 and this resolved my issue for now. This is a good work around until we perhaps update the code to detect the latest version. Now I can try to add an adaptation for the Alesis QSR module that I own.

Thank you! I fixed the crash on exit when no Python present for the next release.

The Mac python detection is a long and sad story, my original plan was to include Python in the DMG built, but the whole package signing process I got never to work. I have a branch that does a smarter search for the install location, which is what I will try next.

2.3.0 now needs Python 3.12, which should be much easier to use via homebrew
