Update original ethernet config section with

<interface type='bridge'>
  <mac address='12:14:10:17:2f:f5'/>
  <source bridge='br0'/> 
  <model type='vmxnet3'/>
  <address type='pci' domain='0x0000' bus='0x01' slot='0x00' function='0x0'/>
</interface>

or

<interface type='bridge'>
  <mac address='12:14:10:17:2f:f5'/>
  <source bridge='br0'/> 
  <model type='e1000-82545em'/>
  <address type='pci' domain='0x0000' bus='0x01' slot='0x00' function='0x0'/>
</interface>

Put in the very botton of the XML config

<qemu:commandline>
  <qemu:arg value='-usb'/>
  <qemu:arg value='-device'/>
  <qemu:arg value='usb-kbd,bus=usb-bus.0'/>
  <qemu:arg value='-device'/>
  <qemu:arg value='isa-applesmc,osk=ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc'/>
  <qemu:arg value='-smbios'/>
  <qemu:arg value='type=2'/>
  <qemu:arg value='-cpu'/>
  <qemu:arg value='Penryn,kvm=on,vendor=GenuineIntel,+invtsc,vmware-cpuid-freq=on,+pcid,+ssse3,+sse4.2,+popcnt,+avx,+aes,+xsave,+xsaveopt,check'/>

  <loader readonly='yes' type='pflash'>/mnt/user/domains/MacinaboxHighSierra/ovmf/OVMF_CODE.fd</loader>
  <nvram>/mnt/user/domains/MacinaboxHighSierra/ovmf/OVMF_VARS.fd</nvram>
</os>

Just in case you want to have nice icon in VM manager

<vmtemplate xmlns="unraid" name="MacOS" icon="/mnt/user/domains/MacinaboxHighSierra/icon/highsierra.png" os="HighSierra"/>
