Answer 1

Based on this article, you may install Rosetta 2 to be able to use brew x86, and then use it to install python 3.7.

To install Rosetta 2:

softwareupdate --install-rosetta

Then, install brew x86 version:

arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

Optionally, add an alias to the ~/.zshrc (or similar) file:

alias ibrew="arch -x86_64 /usr/local/bin/brew"

Now you can choose between brew when you want to install an ARM app or ibrew when you want to install x86 app.

Finally, to install x86 python 3.7 on M1:

ibrew install [email protected]
