Reminds you again that you must use EFI in Mojave OS Installer folder to start your current system. When you enter the system, you will only be in UHD Graphics 630 7MB state without a normal driver graphics card.
1. First you go into the system, Intel UHD Graphics 6307MB
2. Reconstruct the cache and run the Open (Terminal) input. sudo kextcache -i /
3. Replace the file below EFI with the correct config. I uploaded it both in my GitHub and in this post.
4. After all three steps have been completed, you will be surprised to restart the machine at this time.
After you've done all these things in 1.2.3, put the EFI in my DELL-XPS-15-9570-8950-4K-macOS-Mojave.zip file, and then you can execute the fourth step.
Keep in mind that without performing the first three steps directly using the correct files I have made will only restart indefinitely and can not enter the system properly!
