Notes for macOS users

Warning

If you do not use macOS, you can skip this page and directly step to the next subject.

Start by installing the security updates of your operating system. Make sure that you use a macOS version supported by Apple (>12 in 2025, see https://endoflife.date/macos).

For macOS, we will use the Homebrew macOS packaging manager. Copy paste in the terminal the install command given in the Homebrew website. Once this is done, open a new terminal and the command brew should be available. Then, we can use this command to install other software, for example:

# preliminary update: can be long and is not absolutely necessary
brew update
brew install git

We should also install few applications and libraries useful for scientific computing:

brew install llvm gcc make cmake open-mpi fftw hdf5
