If it is not already installed, follow the instructions on the [[https://brew.sh/|Homebrew website]] or in this [[https://mac.install.guide/homebrew/index.html|installation guide]]. Note that the Homebrew default installation directory is now ''/opt/homebrew/'' and not part of the default shell ''$PATH'' (compared to ''usr/local'' on Intel Macs). At the end of its installation Homebrew should show two commands to add it to ''$PATH''. Copy and paste them in the command line.

If not, inspect the error messages and fix them. The ''make'' command may take a considerable time, if you set up the code for the first time. You can try to speed the process up using the parallel make with the option "make -j10 all". "-j" specifies the number of processes that may run in parallel. However, be prepared if to restart make up a few times. 
   - Codesign: When you try to remotely execute unsigned code under macos, it will ask you for permission. This is painful when you run parallel code. Therefore it is advisable to sign the parallel executables. This is a fairly complicated procedure, which you need to look up.
