After reading carefully, if you use intel based python on Mac M1 rasa would not work. But if you use general python it will work. Conda by default uses intel based python on M1. After rasa installation is you see Operating System : macOS-12.6.1-arm64-arm-64bit ( this is good ) and Operating System : macOS-10.16-x86_64-i386-64bit ( this is bad )
I suggest check your python ( intel or general ) by Mac System Settings > About this Mac > More Info > System Report (bottom) > Software > Applications > Python ( Left side ) | It should say intel or general
There is possibility of using conda also here ( I have not tried )
Make sure you use Miniforge3 step to change to arm architecture.
I used python3 venv to create virtual environment. Therefore people have success running with venv ( then you use default python which is general )
And use rasa 3.3+, and python 3.9.16 ( recent ), I think it won’t work with 3.10 as of today, but you can give a try.
Hopefully this may help
