Has anyone used Unibeast to get a working High Sierra on a legacy-only BIOS board?
I know my P7P55D-E-Pro (w/Marvell and J-Micron SATA controllers) is gettin' long in the tooth, but she runs Sierra flawlessly and I've just overcloked my i5-750 to 3.6GHz, so she's no slouch (EDIT: tried HS intall prior to overclocking).
Upgrading directly from Sierra, I got the dreaded "prohibited" sign when rebooting to the installer, with a -v error that the system was waiting for root device. As far as I can tell, that's related to either USB (I disabled USB 3.0 with no luck) or my SATA controllers.
From my reading, those with legacy-only BIOS's are out of luck with respect to High Sierra, but I am wondering if Unibeast has worked around this?
