asstastic Posted October 21, 2017 Author Share Posted October 21, 2017 I was unable to install High Sierra off of bare metal. Did not find a way around the firmware check. I was able to install High Sierra as hpfs+ through Vmware (target disk mode on a real Mac might also work) and get it to boot. I've run into a few system sleep issues under both Ozmosos and Clover that have prevented me from using the system much.
