Can you provide a quick guide on how to install on macOS with Apple Silicon?
```
$ brew install gcc cmake
$ git clone https://github.com/jeffhammond/STREAM/ && cd STREAM
$ make
gcc -O2 -fopenmp -c -o mysecond.o mysecond.c
clang: error: unsupported option '-fopenmp'
make: *** [mysecond.o] Error 1
```
Use a compiler that supports OpenMP. Apple Clang doesn't. Use Homebrew to install GCC or LLVM. Those will have OpenMP enabled.
You may need to edit the Makefile to use CC=gcc-13 or whatever the full binary name is. The program gcc is llvm dragonegg.
