Hi,
Tech Preview readme mentions under Known Issues that new Metal renderer "doesn't work well" on hosts with Skylake CPUs. I've tested on an i7-3615QM and i7-6820HQ and wasn't able to install VMware tools video driver on neither of the two systems. It seems the new Metal renderer doesn't work at all on 10.13 HOS with Windows 10 guests?
Regards
Bernhard
