[RehabMan]

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 ?

gen_debug.sh can be run in off-line mode.
Must provide gen_debug.sh output if you expect help.

I fixed it

No "Problem Reporting" files attached.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.

Use the gen_debug.sh tool mentioned in the FAQ, that way it is less likely you'll omit something.

This ioreg shows no HDMI device connected. No expectation of HDMI audio without an HDMI device plugged in.
