Hello DG,

Has anyone had success getting the Einstein Toolkit to compile on a
M1 powered Mac?  I get "Bad CPU type in executable” when I try.
The newest version (2021_11) may work (if you follow the instructions at
the top of the new user tutorial
https://raw.githubusercontent.com/nds-org/jupyter-et/master/tutorial-server/notebooks/CactusTutorial.ipynb to install homebrew or macports and some of the support packages).

Do you get this error when trying to run or while compiling?

Yours,
Roland
