[HELP] Fresh install of macOS Sierra from a UniBeast installer. Installation went smoothly. However, macOS will not start properly. Screen distorts and freezes after boot progress bar fills completely.

My UniBeast install went smoothly, but I am not able to actually boot into macOS. I get the Apple logo and progress bar like macOS is trying to boot. The progress bar will fill to 100% (though rather slowly). Once at 100%, the screen will distort and I will see a beach ball cursor. The distortion is the Apple logo being duplicated across the screen -- sometimes it'll be white and other times it will be green.

I have tried all kinds of combinations of boot flags. Verbose mode does not provide any information since the boot sequence is beyond the verbose output. I have tried combinations of Safe Mode, Graphics Enabler, NV Disable, and NVIDIA Web Drivers.

I'm at a total loss at this point. Typically when I run into boot problems, I at least have a lead but I have absolutely nothing here.

Does anybody have any ideas?
