Hello Maria,
I've been trying to compile the new stable version of the ETK Lorentz on osx Big Sur and I got all kinds of problems.
This is x86 or M1?
I could compile Lorentz fine on OSX BigSur (x86 in a VM) using both macports and homebrew.
Note that both might have updated their default compilers (to gcc-11) since you last tried.
The instructions to compile are in the jupyter notebook:
https://github.com/nds-org/jupyter-et/blob/master/CactusTutorial.ipynb
I just tried following those instructions on BigSur 11.4, HomeBrew, both freshly updated and things worked ok (taking into account the bugfix in https://bitbucket.org/einsteintoolkit/tickets/issues/2537/sim-setup-silent-p... ).
Here's my OS information and installed packages:
