<< Solved >> Stuck on Apple logo at booting in Catalina 10.15.4

[Yedkriz]

Hi,
I used EFI folder from kasix since he has Z390 Aorus Elite motherboard with Inte i7-9700k.

https://www.tonymacx86.com/threads/success-installation-on-gigabyte-aorus-z390-elite-catalina-10-15-3.292941/

I copied it to EFI folder into Pendrive.
Right after booting it got stuck in the apple logo with the black background screen.
By using verbose this is showing some error. I have attached the image of the error for your reference.

Even though I know using some one else EFI is not advisable but I used it.. I feel really sorry for that.

The only modification I did was, changing the SMBIOS. Kasix generated iMacPro 1,1 SMBIOS, since he has 32GB of Ram.
So I thought, I need to generate a new one with iMac 19,1 - Which matched my specification.
The only difference it has to do with is - i9-9900k.
But its base clock is exactly 3.6 Ghz.

Os details: Catalina 10.15.4

My Specs:

CPU: Intel core i7-9700k
Motherboard: Z390 Aorus Elite with Bios verion 9
Graphics Card: Saphire Rx 580 Pluse 8GB DDR5
SSD: Kingston 250GB SSD
RAM: 1 x 16GB Corsair Vengeance 3000MHZ

I installed windows on anothe ssd and currently using it. But once Mac Os is fully installed I will not use windows any way.

Pls help me to get solve this issue.

Thankyou in advance.

First I want to thank Kasix for the EFI..
Thank You very much joanserramiret, with your guidance & I solved it...

Solution:

What worked for me is that, when we use others EFI folder, always try to install same version of the boot loader to create the Installer or try updating the two files mentioned below.

you have to update your clover boot files, in EFI/CLOVER/ and EFI/BOOT

the file name is CLVOERX64.efi and BOOTX6.efi

You have this files in the newest package installer of clover

All I did was to install a new clover boot loader to one of my spare pen drive ----> then copied those two files (ie, CLOVERX64.efi & BOOTX6.efi) to the bootable USB installer ----> replacing both files in in EFI/CLOVER/ and EFI/BOOT...
And guss what it Just Worked!!!!!

Ok, I give you my EFI folder, it's with a new serial number and switched with your parameters, has the portmapping and all the new drivers and kext's. try it.

I have no words to describe how happy and fortunate I'm to get such a help..... I will keep your EFI and will give it a test

"Once againg I'm so happy & grateful for having joanserramiret for helping me out."
