The Parallels window behaves like a normal Mac window, so you can copy content from your desktop and place it directly into the Parallels virtual machine instance just as you would from one Mac window to another. For developers, this means you can simultaneously run Xcode on Mac and Visual Studio on Windows 8. Parallels Desktop for Mac is a hypervisor-based virtualization solution that makes it easy to run any number of operating systems inside separate windows on your Mac desktop.
