Is a Fusion for M1 running x86 VMs possible, a la Rosetta 2, but for system/kernel/hypervisor-level x86 code, via full x86 emulation? Yes. But, that is not to say that either VMWare or Parallels will want to spend the time and money it takes to write their own emulator and Apple has already stated that they will not allow (unless they change their minds) VM engines to use the Rosetta 2 engine. So, for the normal standard Macbook PRO user who needs access to one or more windows only applications this proves that this can be done (at least once the M1 chip is available in even fast configurations with much more RAM). And, yes the benchmarks show that the M1 Macs are MUCH faster than the current fastest Intel Macbook PROs and that even emulating an Intel Mac they are still faster than the current fastest Intel Macbook PROs (though much slower than the pure M1 Mac running code compiled for it). Once it is loaded for the first application (per benchmark sites that know a lot more than me) it stays running as long as the machine has a need and the memory to allow such. Those first few seconds for the first launch of the first x86/64 application is for the Rosetta 2 engine to load. Much closer to what kjdfhaueiase described than what you said. Rosetta 2 is not a translation engine but an emulation engine. The situation for an Intel macOS Word running in a virtual Mojave or Catalina might be slightly better, but would probably require that the Universal version of Fusion translate each macOS application the first time it is run and for it to save such a translated version within the application itself, making it "universal".ĮMR. How would the forthcoming Universal Fusion manage to translate the 圆4 Word into an ARM-palatable version for an equally ARM-translated Windows 10? I don't think it can be done, much less done on the fly every single time you want to run that version of Word within said virtual machine, because it would be difficult to keep a ready made translation for future, nearly native, use. Not only that, how on earth would Fusion manage to ARM-translate the native code of an application run within said operating systems? Take Microsoft Word, for instance. I doubt all the intricacies of a full-fledged Intel operating system (like macOS Mojave, or Windows 10) can be successfully translated into Apple Silicon code by simply running said operating system one time. The problem, as I see it, is that it is unlikely a virtualization platform, such as Fusion, will benefit from that initial translation of code. Perhaps the resulting ARM code isn't truly optimized (as it would be if the source code had actually been compiled for the ARM architecture) for the M1 chip, but it's code the new chip can understand natively, without the translation overhead. So, if I'm not wrong, that means that all Intel-only applications run on Apple Silicon effectively become Universal applications after they are run for the first time, which means there's no code translation after that first run so, in effect, there's no emulation as such. I know that, after one given Intel macOS application has been initially run on Apple Silicon Macs, it runs very well indeed, but that's because the first few seconds (minutes?) of that initial run were devoted to translating the Intel code into ARM code. You surely know much more about this than I do, kjdfhaueiase, but I'm not sure we can truly say that "the M1 chip is emulating x86 instructions FASTER than Apple's own most powerful Macbooks". Hopefully, VMware will be able to use Rosetta 2 or something like that to make OS X/Intel macOS virtual machines run on Apple Silicon.When it is legally available, you'll be able to install ARM Windows, which, by then, should be able to emulate x86/圆4 Intel Windows applications.You'll be able to create or import virtual machines that run on the ARM platform.Sooner, rather than later, VMware will release a Universal version of Fusion 12, meaning it will run on Apple Silicon Macs natively.In my view, the most likely scenario is this: Therefore, the announcement will be made, if it is made, when the hypothetical product is ready, not now. Ergo, if it is feasible, they are already working on it in one way or another. By giving such a deadline on their own work, they would be saying they are working on it because it's feasible. Would you conclude that, after such a statement they would say "Nope, we won't be emulating Intel Windows"? It would make no sense. Do you seriously expect an official response to your request? Let's imagine that they said something like: "An official announcement regarding Intel Windows emulation on Apple Silicon virtual machines will be made early in February 2021".
