ies=400619) is the core of the updates - it adds amework support (Apple’s recent “So, you wanna do hardware virtualization without a kernel module…” framework), adds the ability to sign the output binary to allow it to use that, and various other things related to Apple Silicon support. Next step: we’re going to download the qemu source, check out the proper version, apply a couple patches, and build it! I have no great advice on parallel Homebrew installs, sorry. If you rely on x86 homebrew, well… uh… fix the ARM stuff that doesn’t build? Or install to a different directory, I suppose. This is fine for most use cases, and it certainly works better than the ARM Homebrew (half the code won’t build under ARM), but it’s no good for ARM native dependencies, and we’re going to be building ARM native qemu. If you use the normal Homebrew install path, you’ll get x86 Homebrew, running under Rosetta. You may have to agree to some license terms as well - it’s been a while since I had a clean install. That’s the first thing I do with any Mac, so I had them laying around. I understand you can also install them from the command line, if you don’t want the full install, by running xcode-select -install. You’ll need the XCode command line tools (gcc and such) to build this, so if you don’t already have those installed, go ahead and install XCode from the App Store.

Installing the Prerequisites: Homebrew and XCode If you’re fine with 1024x768, it certainly works, but… we can do better with open source! Yes, I know Parallels has a tech preview out, and you still can’t change the resolution of a Linux guest. Plus some patches to the source, and… it’s all good fun, I promise! What I don’t promise is that this will work perfectly for you, though I’ll try! You’ll need XCode installed, and we’ll be using homebrew to install some of the prerequisites for building qemu. The main issues are the scheduling problems, and I'm hoping someone in here has done enough work with Mac programming to have some ideas as to where I could start tweaking things to help keep VMs on the performance cores (short of the TSO hacks, which I'd rather not use).
