Niresh, if it helps you at all, this computer did the same thing with your Sierra install. Then the video acceleration kicked in with the update to 10.12.6. There could be the answer in there somewhere.
I first disabled Intel Graphics in BIOS and no difference with 610 card.
Then I installed the modified NVDAReisman.kext (I still have the updated Lilu and Nvidia fix up kexts loaded).
It still did not get to login screen. Please see the most recent vid of the loop it gets to in my Photos library:
I have the updated Lilu.kext loaded and now tried loading the Nvidia GraphicsFixup.kext too.
With the GT 610 installed, there is no difference (no difference with the HD4600 either).
I posted a photo where it repeats over and over (3rd item in this Photos album)
Should I try re-installing HS with your new AMD release? Try a different video card?
Any help is appreciated Niresh!
Yes but when I install the GT610 it doesn’t boot anymore and I get this error:
I tried an old GT 9500 and got a automatic reboot. I posted a video of that to the same link as above.
Thanks! That worked and it updated to .2
it still did not fix my onboard graphics like .6 did with Sierra.
I’d like to keep using the HD4600 but I can put the 610 card in if that’s a better option.
I had the same thing happen. Mine updated to .1 but not to .2.
Same as you it did a reboot. There was a weird green flash as that happened on my monitor too right at the end when it did the auto reboot.
No solution yet.
