If you are trying to run 64 bit Mac binaries on the next generation Mac, that's not Paralllels, that's Rosetta which is built into the next version of MacOS. Parallels lets you run an operating system on top of your operating system. But based on Apple's docs, it won't support emulating Intel CPUs well enough to run an x86 virtual machine, it will only run operating systems which run on ARM.

  Charitably a lot of people (or at least me) are trying to understand how to square that reality with Apple hand leaving that they’re going to “take care of that audience”. I’m starting to worry this is take care of in The Godfather sense of the term.

    It’s possible to do, don’t get me wrong. For example, QEMU[0] does hardware virtualization. Having said that, performance is not the same. On the other hand, there are builds of Linux that are ARM. Windows also has ARM builds[1] and they also have a translation layer to run x86 applications[2]. This is done in software, so there’s a performance hit[3].

Could you point to these Apple docs? That’s the topic I’m most interested in. Thanks!
