I tried to use OVMF shipped with qemu couple months ago and it worked,
but the latest UEFI from the master branch fails to boot either with hvf
or without it if built on macOS and the patch addresses the issue:
https://edk2.groups.io/g/devel/message/59372
I'm able to use UEFI shell on hvf accel if the patch is applied, and I
tried to boot FreeBSD iso with UEFI, it also works on the master branch
of qemu:
$QEMU_CMD -M q35,accel=hvf -m 512 -drive if=pflash,format=raw,readonly,file=Build/OvmfX64/DEBUG_XCODE5/FV/OVMF_CODE.fd -drive if=pflash,format=raw,file=Build/OvmfX64/DEBUG_XCODE5/FV/OVMF_VARS.fd -chardev file,path=debugcon.log,id=debugcon -device isa-debugcon,iobase=0x402,chardev=debugcon -net none -cdrom ~/Downloads/FreeBSD-12.0-RELEASE-amd64-bootonly.iso
I'm not sure about the logo though, I've never seen it.
