Homebrew is the most popular package manager for macOS. As the official documentation says, using the manager is the easiest and most flexible way to install the UNIX utilities that Apple didn’t include with macOS.

Assuming Homebrew is installed following commands install, remove and upgrade packages:

  • Install packages
$ brew install elixir
