I try the old Ivy bridge build on my PC, and install macOS Catalina on it.
The install goes very smoothly but maybe it reboot to first time setup, I get the blank gray screen and a cursor can move, when I click the left button of mouse, the cursor gone.

Before it enter this screen, it print some logs on the screen(maybe I set something like show logs at plist...).

I try to set the bios to use iGPU, I still get the blank screen with cursor, but the background is black.

This is my build:
Asus B75M-A
Core i3-3220@3.3GHz
Asus GT640-1GD5-L (GeForce GT 640 With 1gb GDDR5)
6GB DDR3 1600

And I attach my EFI folder below...

Sorry for my bad English...
