This is my EFI Folder for Hackintosh for this config : -Motherboard : Gigabyte H370-DH3 -CPU : Intel Core I5-9600k -GPU : Sapphire AMD Radeon RX 580 8 Go -RAM : 32GB DDR4 2666Mhz
I shared my clean EFI folder for those who have the same specs, you just have to change the SystemSerialNumber and the SystemUUID by generate a new with GenSMBIOS, follow this guide : https://dortania.github.io/OpenCore-Install-Guide/config.plist/coffee-lake.html#platforminfo
I hope it will help you. Peace !
