Homebrew
Homebrew installs the stuff you need that Apple (or your Linux system) didnt. Homebrew installs packages to their own directory and then symlinks their files into /usr/local. Homebrew wont install files outside its prefix and you can place a Homebrew installation wherever you like. Trivially create your own Homebrew packages. It&s;s all Git and Ruby underneath, so hack away with the knowledge that you can easily revert your modifications and merge upstream updates. $ brew edit wget # opens in $EDITOR! Homebrew formulae are simple Ruby scripts: Homebrew complements macOS (or your Linux system). Install your RubyGems with gem and their dependencies with brew. "To install, drag this icon..." no more. brew cask installs macOS apps, fonts and plugins and other non-open source software. Making a cask is as simple as creating a formula.
