Install brew

there are lots of GUI programs, we cannot install nicely using pure nix. There is brew-module in nix-darwin. /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh) What is benefits of this ? we can install/uninstall applications using nix don’t forget to do brew analytics off
