Hi Moucheron78, I had the same issue with my Father's MP.
I noticed that the firmware didn't get updated after installing macOS 10.3.4.
I could't get another graphic card 'official' to proceed again and see how the MP handle the update.
Do you have an official Apple GPU? Swap it with your AMD and install again the update

This is a good new merci! just the right way to install the update with an official card and that all.
Except that the card R9 380 does not work despite the layout with an official card. I can start in recovery mode or without the extensions but I have no graphics acceleration and in normal mode the freeze card with black, red and afteract screens of the boot.
