It isn’t impossible to do, but it requires so much effort that it probably just isn’t worth it. But you can’t really do that with a virtual machine, especially one that is running 32-bit code, as well as 64-bit code. That isn’t as good or as reliable as compiling the source into ARM64 to start with, but it is better than nothing. Rosetta 2 translates the 圆4 code on first-run into ARM64 code, it doesn’t emulate it. Use RDP, TeamViewer or something and you can even control it from the Mac. For the price of the emulation software(2), you could probably get a half-way decent Windows PC to run that old software. But the question is: why bother? Native software will always be faster, by orders of magnitude. Maybe with one of the following generations, the Apple Silicon could possibly do it at a reasonable speed, but the AMD and Intel chips are also advancing, so it is always a game of diminishing returns. Likewise, later, when PowerPC had lost its speed advantage to Intel, the original Rosetta emulated PowerPC code on Intel, because the Intel chips were much faster than the PowerPC chips, Rosetta software was a bit laggy, but just about usable.Įmulating x86 and 圆4 and running a second OS under that emulation is going to make it slow, in comparison to running it on a Windows PC or using the native equivalent on the Mac. Just look back to the PowerPC days of Apple, although PowerPC at the time was faster than Intel, the x86 emulator, VirtualPC, was an absolute dog.

Somebody could certainly write an x86 emulator, but why bother? Microsoft will be more interested in selling you a Windows in the Cloud VM than providing any support for Windows to run like a comparative sloth under emulation on the M1.

Apple has started their ARM game as far forward as possible, to not fall into the Intel/AMD trap(1), at least not for the next 10 years or so. And then, it will only runly ARM64 code, not ARM32 code, so some Windows ARM software won’t work on the M1 Mac even then (Apple has explicitly built the ARM32 compatibility out of the M1, it is a pure 64-bit chip, it won’t even run ARM32 iOS apps). The only solution at the moment is to run Windows on ARM in a virtual machine (Parallels) on the Mac.

One part of the problem is that Rosetta can only run 圆4 code, it can’t run x86.
