Hi Igor,

I have now tested various OVMF versions with the latest QEMU (commit
aaaec6acad7c).

When using edk2.git-ovmf-x64-0-20170726.b2826.gbb4831c03d.noarch.rpm
from [1] macOS does not boot and gets stuck. The CPU usage goes to
100%. I haven't confirmed this but this OVMF build should have both
198a46d and 072060a edk2 commits in it, based on the build date.

The OVMF blob from Gabriel Somlo [2] hangs on the OVMF logo screen and
it too results in 100% CPU usage after hanging.

I am using "boot-clover.sh" script from my repository [4] to test the
various OVMF versions.

The only OVMF blob which works with the current QEMU for booting macOS
is the one from Proxmox [3]. Unfortunately, I don't know the
corresponding commit in the edk2 repository for this working OVMF
blob.

It would be great if someone else could reproduce these results too.

Thanks,
