It seems to have completely b0rked my machine, boots to a weird white/gray screen, gets an IP from DHCP (despite being set to fixed IP) and I can't get into it remotely.
Will have to play around with it more later, but I'm not sure what's gone wrong yet!
I've no idea what's happening with this machine, I left it this morning unbooted and I thought turned off - but came home to it this evening sat on the login screen and working fine. Absolutely no idea what's going on with it, still running 10.15.1 Beta (19B86a) at the moment. It's like that update rolled itself back and self-healed, I've no idea
Did anyone try to install Catalina with 5700XT installed? On my computer, it is glitching strangely. I tried with or without whatevergreen(1.3.3 & 1.3.4), lilu is v1.3.8. The model is iMacPro1,1.
BTW the big white box is the mouse. It appears that the screen is shifted to the upper left so lots of contents are lost, with some part of the installation window appears at the right side of the screen.

Also, does anyone know why the boot log says: "systemWillShutdown"? This does not seem normal to me. What does everyone's computer behave when performing shutdown? Does it go through the normal shutdown sequence? Or it just hangs for a few seconds and suddenly the computer turns off.
