I hate to give Apple any ideas... but I've always wondered why macOS/iOS support falling back to software rendering, when all of their devices ship with a known GPU configuration. Without that fallback, getting the OS running on non-Apple hardware would take a lot more work.

Presumably they use it internally. IIRC there are drivers for VirtIO devices in modern MacOS, implying they use KVM/QEMU for something.

  It's also used when you load into the recovery partition, IIRC. It may be redundant nowadays, but it's a nice redundancy to have for sure.

    Makes sense to have that working if there are gpu hardware issues… which did happen for many years

Apple has documentation on installing OS X in a VM: https://developer.apple.com/documentation/virtualization/installing_macos_on_a_virtual_machine https://developer.apple.com/documentation/virtualization/ins... While _this_ usecase obviously isn't officially supported, it does seem like they support VMs in some capacity officially.

  This document is about running macOS in a VM on Apple's own hypervisor. Wouldn't this count as official support?

    GP's 'this' refers to the submission, i.e. macOS in a container. (Aside: I hate 'a Docker', a Docker what? Image? Container? Registry?)

      yeah, "a Docker" is incomplete and incorrect. and annoying. It could have been a character limitation, I guess, but edit it down so it makes sense instead of just ending the sentence prematurely. "Do you have a Facebook? Or an insta?" No one cares about correctness at all, anymore.

        Who calls it instagram? Like Reebok->RBK. Only old out of touch people say instagram or reebok

        I honestly don't know if that is sarcasm. If not I'm gleefully both old and out of touch :-) P.S. For bonus points, ask me how I pronounce INXS :-D

        I pronounced it inks for the longest time
        dylan604 4y ago
        that's an interesting take on it. we cant get INXS, but we're okay wth the omttng lettrs in modrn compny names and terms lke ROTFLMAO
