Mid Install Reboot Catalina

[gotjoshua]

So, i am pretty sure I have the Bios Settings correct. and
I managed to enable OpenCore debugging.

I get to the selection screen for install or clear nvram, the apple screen comes up and the progress bar gets barely past halfway and then reboots. I can't figure out how to get any debug info for whats going on behind that progress bar and what goes wrong at the end. I tried CMD + L and CMD + V but nothing changes, it just reboots again and again...

any help?

What happens after the reboot? Mine took 3 reboots till the install was finished.

Thanks for the reply! well the bar never finishes, and the logs indicate an error at the end.
EDIT: and I also get the "your computer restarted because of a problem screen after reboot, before the apple and the loading bar come up. the reboots always seem to start the install over again, i think i let it run for more than 5 times. I will make a fresh install media and try another usb stick as well... it WILL work.

Small update: I tried downloading the Catalina installer again and it was a slightly newer version: 10.15.03 vs 10.15.02 Also tried Big Sur 11.1 (fails even faster) I also tried both OpenCore v 0.6.5 and 0.6.4 DEBUG

It seems to keep failing just after "SmcReadValue"... Does anyone know a way to get more detailed panic info?

I worked through the OC troubleshooting for that EXITBS line and tried pretty much every permutation of the options that they declare as relevant.

Any suggestions or help would be very appreciated!

Success! I managed to get past the kernel panic (which was related to the on-board GPU).

Based on the Desktop Comet Lake Guide I had to adapt the UHD 630 section:

        <key>Add</key>

                <string>Intel UHD Graphics 630</string>
            </dict>

EDIT: I got quite a bit further than this and documented the process in a gitlab issue on my fork. The above properties will boot but are far from optimal. Stolenmem was not needed in the end, and I used Base64 encoding as it seemed to get the most consistent results.
