GROMACS can be compiled on any platform with ANSI C99 and C++17 compilers, and their respective standard C/C++ libraries. Good performance on an OS and architecture requires choosing a good compiler. They recommend gcc, because it is free, widely available and frequently provides the best performance. If you are running on Mac OS X, Apple has unfortunately explicitly disabled OpenMP support in their Clang-based compiler so using gcc. Details guides for installation are here
