Thank you for wanting to help, I appreciate that.
The error was related to memory allocation. Either stuck at the ++++++, or just a line saying "Error Allocating 0x33ac pages at 0x000000000ee00000 alloc type 2"
I was able to finally boot on macOS using this AptioMemoryFix.efi.
I also had to create a USB stick with UEFI Shell and save the memory map (MEMMAP), study it under windows to set the slide parameter (was slide=129 for me).
The procedure I followed is here: https://github.com/wmchris/DellXPS15-9550-OSX/blob/10.13/Additional/slide_calc.md
Strangely, the second boot did not work and I had to remove the slide=129 parameter.
So big progress!
Now, I will have to redo all the SSDT work and USB mapping for this motherboard. Thankfully, all the rest is similar (same CPU, and X99 platform).
Will also have to try OC and match what I had on the ASUS X99 DELUXE.
Will keep you posted.
AptioMemoryFix.efi cannot be used with any slide boot flag. In principle the version implemented in my original EFI-Folder distribution should work. Sometimes it is necessary to reflash the BIOS or reformat the boot drive to prevent memory allocation errors. Also enabling "Above 4G decoding" in your BIOS settings might help to prevent memory allocation errors.
