I've reached the first boot user setup, but the graphics are mangled. I picked up an Elite 8300 with a i5-3450 and added a GT 710. I was running High Sierra on this successfully, but the upgrade to Mojave didn't work and decided to do a fresh install, instead of troubleshooting, since it's a system I use for writing that only has a few programs installed. But not having much luck.
When the third boot completes, where I'm choosing language and location and such, I get a light gray rectangle filling the top left side of the monitor, with a black band running down the right side and thinner along the bottom. I believe this is the first screen and something about the graphics isn't rendering correctly. Perhaps they are stretched. I do have a working cursor, but it disappears if I click anywhere.
Booting takes around 20 minutes due to several timeouts (busy timeout[0], 240s: 'AppleACPICPU'). I've tried several things in Clover:
Safe mode - boot fails
Inject NVidia - no change
Inject kext - Seems to boot a bit faster, but same outcome
I'll pull the files and get screencaptures tomorrow morning. Apologies, but I'm late for bed and the kids wake early. Hoping this might be an easy fix someone can point out. On the funny side, while this last try was taking forever, I was reading 9 to 5 Mac and noticed the report the next version of Mac OS will separate iTunes out into several standalone apps. If If I'd read that yesterday, I'd have put HS back on and run it until the new OS launches. But now I feel so close and just want to finish the job.
Thanks ahead
