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?
