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

  • VNC is used to connect to the guest UI
• The qxl virtual video device is used (part of the standard kvm qemu install)

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