Install skippbox software via homebrew on OSX.
You can either directly install a software with:
$ brew install skippbox/tap/kmachine
Or add the Skippbox tap to your Homebrew installation:
$ brew tap skippbox/tap
$ brew install kmachine
GUI apps (like Skippbox), will need Homebrew Cask to be installed to works (asuming you added our tap as demonstrated in the previous steps:
$ brew tap caskroom/cask
$ brew cask install skippbox
