OSX 10.15 Installer vs Normal Boot

I almost got 10.15 working on an Acer C740 Chromebook, with a Celeron 3205u. Yes, I know the FAQ says to not use Pentiums or Celerons as they won't work. But with the experience I had, I'm curious if anyone knows why.

I got it to a point where I could boot it to the 10.15 installer via Open Core. The graphics/display looked totally fine during the installer and everything played nicely with graphics. It even seemed like it was accelerated, as in no screen tearing and no abysmal framerates. The drivers seemed like they were working.

Now installation is done and I'm getting stuck on the IOConsoleUsers: gIOScreenLock State 3.... error where the screen goes blank at the Apple logo and basically loops flashing this message. The Open Core guide says this is a GPU problem, and I have no doubts that it would be that.

So... the installer graphics worked just fine, but the OS doesn't want to play nicely even though it clearly can as shown by the installer. Does anyone know why?

P.S. the flare is question, but if any of you have a solution to try (that's not on the guide because I tried those) feel free to send that too. I'm not expecting anything, but willing to accept any tricks up your sleeves
