as I already mentioned, for some reason this does not work on a macOS
10.15.7 machine I have access to.
Strangely enough, I needed to run first a command
brew cask
(don't know what it actually does, it did
download (probably git-cloned) something
==> Tapping homebrew/cask

brew cask
after which
brew install --cask sage
did seem to work.
Starting sage brought up the popup:
--
“SageMath-9.2” cannot be opened because the developer cannot be verified.
macOS cannot verify that this app is free from malware.

So I did
% sudo xattr -r -d com.apple.quarantine /Applications/SageMath-9.2.app
xattr: No such file:
/Applications/SageMath-9.2.app/Contents/Resources/sage/local/share/jupyter/kernels/sagemath/doc
Apparently there is a dangling link pointing there, but OK. It has done the job,
and have an apparently working sage in terminal. Jupyter is broken:
% sage -n
┌┐

└┘
Please wait while the Sage Jupyter Notebook server starts...

The Jupyter notebook requires ssl, even if you do not use
https. Install the openssl development packages in your system and
then rebuild Python (sage -f python3).
Also, the app in /Applications/SageMath-9.2
does not quite work, most stuff from the menu's does not launch, etc.
So this is not really working well, still. :-(
