KVM OSX Guest 10.11 (El Capitan) with Clover

• Some notes about this approach:
  • An OSX Installer USB drive for Install OS X El Capitan is created
  • Clover is then installed on the USB drive
  • Clover Configurator is then run on the USB drive
  • The USB drive contents are copied to the VM host
  • VNC is used to connect to the guest UI
• The qxl virtual video device is used (part of the standard kvm qemu install)

1. Gemfile

gem 'browserify-rails', '1.5.0' # until fix: https://github.com/browserify-rails/browserify-rails/issues/101
gem 'react-rails'

Browserify-rails allows to use browserify within assets pipeline. React-rails is here only to allow to use #react_component (and thus, prerendering).

Note that jquery-rails can be removed from Gemfile, the npm version of jquery and jquery-ujs will be used instead.
