Installing OS X 10.10 Yosemite using VMWare Fusion
This guide will show you how to install a fresh copy of the new OS X which was announced by Apple yesterday. OS X 10.10 or Yosemite as it is known, is the latest Macbook and iMac operating system from Apple and comes with a list of fantastic new features. It hasn't been fully released yet and this guide will use the Developer Preview.
Apple stated that the public can try out early versions and for the first time since 2000, they are letting a large number of outsiders get a hands-on look. No final release date has been set but expect to see it around September.
