I'm not an ACPI expert but that certainly seems a plausible solution - I'll have to defer the final review to someone else though. The quickest way to get this reviewed is to follow the procedure at https://wiki.qemu.org/Contribute/SubmitAPatch which is basically send a "git format-patch" email to the qemu-devel mailing list. Adding as CC the appropriate maintainers shown by running "./scripts/get_maintainer.pl /path/to/my.patch" as indicated in Section 2.1 "CC the relevant maintainer" will help ensure it gets the attention of the right people.

So I built qemu master from github and it has the same problem, whereas git tag v5.0.0 (or 4.2.1) does not, so something between v5.0.0 release and the last few days has caused the problem. Here's my qemu script, pretty standard macOS-Simple-KVM setup on a Xeon host: qemu-system-x86_64 \ -enable-kvm \ -m 4G \ -machine q35,accel=3Dkvm \ -smp 4,sockets=3D1,cores=3D2,threads=3D2 \ -cpu = Penryn,vendor=3DGenuineIntel,kvm=3Don,+sse3,+sse4.2,+aes,+xsave,+avx,+xsa= veopt,+xsavec,+xgetbv1,+avx2,+bmi2,+smep,+bmi1,+fma,+movbe,+invtsc = \ -device = isa-applesmc,osk=3D"ourhardworkbythesewordsguardedpleasedontsteal(c)Apple= ComputerInc" = \ -smbios type=3D2 \ -drive if=3Dpflash,format=3Draw,readonly,file=3D"/tmp/OVMF_CODE.fd" \ -drive if=3Dpflash,format=3Draw,file=3D"/tmp/macos_catalina_VARS.fd" \ -vga qxl \ -device ich9-ahci,id=3Dsata \ -drive id=3DESP,if=3Dnone,format=3Draw,file=3D/tmp/ESP.img \ -device ide-hd,bus=3Dsata.2,drive=3DESP \ -drive id=3DInstallMedia,format=3Draw,if=3Dnone,file=3D/tmp/BaseSyste= m.img \ -device ide-hd,bus=3Dsata.3,drive=3DInstallMedia \ -drive id=3DSystemDisk,if=3Dnone,format=3Draw,file=3D/tmp/macos_catal= ina.img \ -device ide-hd,bus=3Dsata.4,drive=3DSystemDisk \ -usb -device usb-kbd -device usb-mouse Perhaps something has changed in Penryn support recently, as that's required for macos?
