Parallels as of late announced the upgrade of its platform for visualization Desktop 8. The new assembly was supported by the operating system OS X 10.9 Mavericks. At the moment, the software does not support a developer to build a virtual machine from scratch. However, you can upgrade to the Mavericks with an existing machine already running with OS X.
Apple announced a new release OS X 10.9 Mavericks operating system at the WWDC 2013 on June 10. This is the first major upgrade of the operating system after last year’s release of Mountain Lion.
Application developers have access to the pre-assembly of the platform, and users will have to wait for the final version until the autumn. Among the key features of the new desktop OS include the introduction of tabs in the file manager Finder, enhanced support for multiple monitors and a number of improvements related to the interaction of the system with the hardware the Mac.
Add that Apple strongly recommends that users do not install test builds of OS X Mavericks on their computer since it’s only a preview not the final version of the operating system, and it may at any time cause a failure or loss of files. If the Mavericks will fail under Desktop 8, you can always delete the virtual machine and continued to work without any loss.
