problem Dell Latitude 5490 is failing to even install the MacOS

[Incognitiv]

So... it's my first ever laptop in my life, and it was definitely used from what I see, meanwhile I was - and still am - a regular desktop user and if it comes to PC, I know what parts I'm putting in my PC case... doesn't matter. Anyway, the specs are as below:

• BIOS version - 1.34.0 (updated it as soon as possible, before it was 1.6xx something, I don't remember)

• Processor: Intel Core i5 8350u

• 8 GB RAM (one stick only which is rather problematic, because from what I see it's a stick from... some Lenovo, called "Lenovo FRU 01AG710")

• NVME disk 256 GB from Samsung, called "MZ-VLB2560" (or "S41GNX0M117758", and no, I can't use a regular SSD because I didn't get any adapter with this laptop)

• GPU - Intel UHD Graphics 620

• Audio Controller - Realtek ALC3246

• Wi-FI Device - Intel Wireless... and that's all the BIOS says, but I guess it's this "thing", called "8265NGW".

 

or way better specs after I used Linux live cd installation to check exactly:

So far I managed to:

• download a lot of random EFIs, even from this website, then mount them, and... even if one worked, it worked only up to a certain point where it was basically hanging the laptop at 77.5%

• download some sort of a configurator (opencore efi maker afair) and used it within VMWare / Ubuntu in order to create a config, but it was also fruitless and couldn't bring it any further

In the end, I managed to create this EFI configuration, which makes the laptop stuck at the Apple logo and does nothing at all, no matter how long you'd be waiting. I also added possibly all the necessary (and not necessary) "Tools" (which, by a miracle, work).

I'm not sure what to do, I'm guessing there's still something wrong or unsupported so... I need advices. Also I don't even know what kind of MacOS I am supposed to install at all, so I downloaded them all and right now I am juggling Ventura, Big Sur and even Sonomo installations.

-Users with IGPU can use -igfxvesa bootarg for easy installation
-Delete old EFI folder and paste new. Don't use merge files
-Don't use Drag and Drop into EFI partition. Use Copy/Paste instead
-Reset NVRAM one time - with OpenCore use entry "Reset Nvram" / with Clover use F11 key on boot screen
