I'm right where you are, black screen with a mouse pointer. I can move the mouse, if I wiggle fast it gets larger, I can even do command-shift-4 and draw a box for a screen grab. Sometimes the pointer turns to a text insert cursor, which leads me to believe there's some text hidden somewhere. I'm at a loss of where to go from here. Attached config, at this point I don't even know where it all came from at this point as I've been hacking away at this for close to a week.I could use some assistance. I decided to build a second one of these machines. But this time without the RX 580, and I can't for the life of me get the Intel onboard to work post-install. I'm using a i9-9900K CPU. If I put the RX 580 in the machine, it works fine following all of the same steps. But, if I do IGPU only, it never gets past the 2nd reboot where it starts the process when you enter your name/etc at the start of OS X being run for the first time, it black screens right before the Apple logo normally appears with the bar going across the screen.
I get the black screen with "gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0" being the last visible line. Unlike others though, I'm not losing my port signal on DP or HDMI, I just get a black screen with a cursor in the top left corner indefinitely.
I've tried every possible suggestion on the forums, using platform-ids, injection, no injection, framebuffer patch, etc. And I get varying results, but in 99% of the case it's the same end result, just a black screen with a cursor. I've also tried the known Properties config for our motherboard and that too doesn't work.
I just can't figure out how to get past the post-install. Everything works great for the initial install, and the first reboot where the install continues, but the first time I try to boot into the OS, I have this black screen issue. I'm not sure where to go from a troubleshooting perspective any longer...
Any thoughts for anyone who is running IGPU ONLY with no discrete video card installed? Has anyone else gotten this system up and running with IGPU only?
Config: ROG STRIX Z390-I Gaming, 9900K, 32GB RAM, M2.1 NVME Samsung 970 Pro 512, AMD 5100MX GPU, though I'm not plugged into it right now. (removing the GPU is a last resort as this has a VERY complex cooling solution that would need full disassembly.
Booting with GPU gets stuck one screen sooner "gIOScreenLockState 3" but then goes black and the monitor turns off.
