Hello, I have been messing around with the AMD hw acceleration instruction in the other thread (and that did work except the bootpicker), today I wiped all the drives and tried the instruction in this thread.
Everything from this thread post #1 works properly, except the bootpicker does not show up, my screen stays black until the logon.
However, as others reported, if I press 1 during the blackout period, it boots into 10.15. If I press 3, it boots into 10.14. If I press 2, it boots into 10.15 Recovery.
-I tried two different 4k monitors. I tried display port cable, and hdmi cable, and tried all 4 ports on the GPU (2 hdmi, 2 displayport).
-I tried a second gpu I have, "Zotac GT 710 Zone". It had the same black screen.
-I then put in my Apple OEM GPU, and it showed the bootpicker screen properly, and booted according to the pick properly.
I kind of have the feeling there is no signal going to the monitor until right before the logon screen. This is just my gut, I don't have any evidence. The progress bar shows up at the bottom for a split second right before the logon screen. I don't recall if that progress bar showed up at all when I was running plain 10.14 without any mods whatsoever.
If there is any testing I can do to help, I'd be happy to. (although this is all new to me. I did read both threads in their entirety over the past two weeks).
Edit: I just checked the ebay add I got the used Rx580 from a few weeks back. It said "Has ETH mod bios installed". I don't know if this is significant or not, but figured it was worth mentioning.
Thanks,
Nick
