I have done all from #1 and i have the problem with rebooting when connected.
How and where i can add these :
framebuffer-con1-pipe=<12 00 00 00>
Can you please explain me step by step what i have to do?
Now I changed to 14.1.MacBookPro14,3 is a poor choice. Use MacBookPro14,1 or MacBookPro11,1.
Due to this huge mistake, I did not check anything else.
