Thanks for your guide man. Right now I am making a really funny experiment, following your guide, I could install Mac OS X in my new laptop Asus Strix Scar 15 2022 Core i9 12900H, it worked but of course with no video asceleration at all. However, I bought a Sonnet eGPU, and I could find a Radeon RX 570 4GB for testing. Because the laptop has a USB4/Thunderbolt 4 port, I wanted the GPU recognized as a PCIE device. (I tested that way before and it worked.) Yes, it worked!!!. My laptop is most like a CPU right now (jajajaja) but the most work that I do in Mac OS X I can do it always in my desktop. Looking that It worked, I ordered a AMD Radeon RX 6800 16GB to make a better test and don't want to invest in a really expensive GPU.
Here some images about the build and, of course, showing is working. I use a USB SATA SSD. I will install inside a NVMe because, before I open my laptop, I wanted to be sure that the experiment would work
.
The NVMe and the new GPU are on the way to improve the laptop and well to make a more detailed thread because I disabled the iGPU, the dGPU and the eGPU could work otherwise I had black screen but at the end it worked.
As I said right now my laptop in OSX is a CPU, I have to use a Monitor, Keyboard, Mouse, the eGPU and the Graphics Card, but is so perfect for me, because I can take my Laptop everywhere, I use windows just for gaming and this laptop has the RTX 3080 ti 16GB 150W, is so powerfull, but I don't have to have two workstations, I don't use windows or osx at the same time so, well I want to look how is the performance of the RX 6800 16GB over Thunderbolt and if it is good enough I will keep it the Build in this way with the improvements I am planning.
