A new beta build of VirtualBox, Sun’s Oracle’s free x86 virtualization software, makes it possible to run Mac OS X as a guest operating system…no shenanigans or flaming hoops to jump through, just pop in the $30 retail Snow Leopard upgrade disc and go. This had previously only been possible with some awkward Hackintosh-style maneuvering, or using recent editions of commercial virtualization products.Īt this early stage, performance is fairly sluggish, the screen size is fixed and there’s no sound support, but the OS otherwise appears to run feature-complete (including networking and USB).
