And the VMware Tools work too. I successfully tested the Windows 11 Insider Preview on VMware Fusion for Mac, and it works. Tags: Apple, macOS, Microsoft, VMware, Windows.
![]() Apple’s limited Rosetta 2 emulator provides one of those Indiana Jones rope bridges across the chasm. What stands in the way?Though they may seem to carry out a very similar function, there’s a wide gulf between emulation and virtualization. But there’s more to come that could improve the transition from Intel to Apple silicon for Mac users—like a virtualization app that would let us launch 10.15 Catalina or previous Intel-only versions of macOS, or Intel flavors of Windows, Linux, and other operating systems. It’s also incredibly useful for app developers and technical support staff, who often need an array of operating system versions for testing and troubleshooting.Emulation generally works at an instruction level. Such an approach can give you the best of both worlds, where you can use the latest hardware and operating system while still having access to previously purchased apps that run only in unavailable machine configurations. Crossing the Chasm: Emulation and VirtualizationBoth emulation and virtualization let you run one or more apps or entire operating systems within a distinctly separate operating system from the one that manages the host computer—the actual computing hardware. It can preserve an investment in software for individuals or globe-spanning corporations that continues to meet a need, especially when nothing newer is available at all or for a reasonable upgrade fee. Rosetta 2 has the advantage of converting Intel processor code to Apple silicon instructions on the M1 chip, which is both optimized to macOS’s needs and substantially faster than previous Intel CPUs.Emulation can be used for serious purposes, such as allowing vital business software to keep running even as the hardware it requires becomes obsolete and unavailable. And there are hardware emulators, including chips that can be programmed to reconfigure themselves to emulate other chips!)Because emulation works at such a fundamental level, it can be quite slow if its host processor isn’t significantly faster than the one it imitates. (There are even emulators nested inside other emulators, notably in the telephone network and other long-running systems. When an app or operating system loads within an emulator, the emulator transforms its instructions into a version that works natively on the processor on which the emulator is running. These apps or operating systems believe they are running on a bare-metal processor—they’re the proverbial “ brain in a jar”—and there’s only a modest bit of overhead that makes them run more slowly in that environment.Parallels Desktop and VMware Fusion for Intel-based Macs, for instance, are virtualization apps that rely on a hypervisor to run other Intel-based operating systems inside their virtual machines. A virtualization app creates virtual machines that provide a framework to execute app or operating system code natively with the same processor that runs the host computer’s operating system. All of these emulators run in a Web browser, remarkably.In contrast, virtualization works at a higher level. The Internet Archive has early Mac emulators that let you, for example, launch the Mac version of the Oregon Trail game, and even emulators that keep Adobe Flash alive for preserved animations and interactive games. Iphone unlocker v22 serialRosetta 2 is a 64-bit Intel x86 emulator for Apple’s M-series Macs, but it’s not a full emulation environment and doesn’t support 32-bit apps. And, realistically, many data center hardware components are designed to be hot-swappable, reducing the likelihood of downtime even further.Apple’s solution for the transition from Intel processors to Apple silicon is to leverage emulation, albeit in a way that doesn’t offer virtualization on top. If the host hardware were to die, my provider could migrate a disk-image backup onto a new host in minutes. I run a virtual private server, a slice of a machine running under a hypervisor, that is nearly the same as—but far cheaper than—having my own server in a rack somewhere. Instead, it’s a way to install and boot natively into Windows on an Intel-based Mac, where Windows is the host computer’s controlling operating system.)Hypervisors are also used in data centers and by businesses to extract the maximum value from hardware by running multiple virtual machines simultaneously in a single high-performance server. You can set up multiple virtual machines with a single app and run them side by side.(Boot Camp, by the way, is not virtualization. Under Michael Spindler, Steve Jobs, and Tim Cook, Apple has been unsentimental and forward-thinking.Apple’s timeline of emulation and virtualization looks like this, although there are a few tiny steps and extra nuances that could (and do) fill Wikipedia pages: Apple’s Emulation and Virtualization JourneyI’ve long been impressed by how effectively Apple has provided transitions across generations of its hardware and operating systems. (You can sign up for both the Parallels Desktop beta and the Windows Insider program that lets you download the Windows preview for free.)To make your head explode slightly, if you run Windows for ARM within Parallels Desktop for M1, Microsoft provides an Intel emulator that can run both 32-bit and 64-bit apps written for Intel versions of Windows! (Microsoft released the 64-bit update in December 2020 the 32-bit version has been around since 2017.)With those differences between emulation and virtualization in mind, let’s look at Apple’s path to the present and where the future might still lead in its transition to Apple silicon for all Macs. Parallels already has a Parallels Desktop beta out for M1-based Macs that allows Microsoft’s ARM-native Windows preview to run natively, as it’s compatible with Apple’s ARM implementation. Vmware Fusion Windows Emulator Mac OS X AroundPowerPC to Intel: The original Rosetta emulator allowed most PowerPC software to function on Intel-based Macs. The “Classic environment” was available from the public beta of Mac OS X around 2000 through 10.4.11 Tiger in 2007.
