I have done all from #1 and i have the problem with rebooting when connected.
How and where i can add these :
framebuffer-con1-enable=1
framebuffer-con1-pipe=<12 00 00 00>
Can you please explain me step by step what i have to do?
Thank you


MacBookPro14,3 is a poor choice. Use MacBookPro14,1 or MacBookPro11,1.

Due to this huge mistake, I did not check anything else.

Now I changed to 14.1.
After this change my HDMI works now. But the problem is that I don't have sound on tv. Can you take a look at the file please ?
