Update: Problem solved. Created a env with intel86_64 with ```CONDA_SUBDIR=osx-64 conda create -n kwant-intel python=3.10 -y`` and then followed through all the instructions, and now the problem is gone. I guess there are some incompatibilities with M1 silicon to use ```mumps``` or ```OpenBLAS```
Thanks very much.

However the first step I tried importing kwant with ‘import kwant’ I encountered the kernel crushing with the following message : And when i tried to test ```python -c "import kwant; print('Success’)``` it returns ```zsh: abort python -c "import kwant; print('Success’)”````` which suggestes mismatched libraries. I tried other ways such as build from sources but all kind of did not work very well and the kernel keep crushing, and trying to run I am currently using MacBook Apple M1 MacOS 15.3.2 (24D81), I need some further instructions and help on how to proceed to install kwant and use it on my system.
