We've previously shown you how to install OS X Mountain Lion on a virtual machine by using iAtkos ML2, which is great practice for installing Mac OS X on your actual computer. And now that Apple has released OS X Mavericks, it's only fitting that we show you how to install Mavericks in a virtual machine as well. Unlike in previous versions of this guide, we'll be using the newly-popular "Niresh" distro of Mavericks instead the old iAtkos distro (which is no longer publicly available for free). While we've already shown you how to install Mavericks on your actual computer with Niresh, it also works great with virtual machines.
