'How to install OpenMP on Mac M1?
I am currently studying to become a computer engineer and I need to work with OpenMP. After some research, I'm still having trouble installing it (#include <omp.h> is still not recognized). I tried libomp and llvm (with homebrew), but I must have made a mistake along the way. Has anyone been able to use OpenMP on mac M1?

A simple approach is to use brew https://brew.sh/ to install GCC or LLVM (clang), and then use that compiler. You need to tread carefully, though, since the MacOS environment includes X86 emulation which can be confusing.

M1 chip seems doesn't install llvm in the proper location.
brew install llvm
cd /opt/homebrew/opt/libomp/lib
if libomp.dylib is in the folder /opt/homebrew/opt/libomp/lib:
cd /usr/local/lib
sudo ln -s /opt/homebrew/opt/libomp/lib/libomp.dylib libomp.dylib
