WARNING:Continue on your own risk. I share my config with no waranty. If anything happens to your iron, its not on me
I recommend using OCAuxiliaryTools or propertree as config editor.
Kernel
If your core count differs from mine, then your should edit three lines in kernel > patch. Edits are following:
B8 06 0000 0000BA 06 0000 0000BA 06 0000 0000
The edits are simple, there are in HEX format. here is the syntax: BX <phys core count> 0000 0000
HEX TABLE
| DEC | HEX |
|---|---|
| 2 | 02 |
| 4 | 04 |
| 6 | 06 |
| 8 | 08 |

elsewhere
You do best if you check recomended settings for your chipset. Since mine is B450, I don't need SSDT-CPUR.aml and I also have different settings elsewhere.

PlatformInfo
It is required that you generate yourself new SMBIOS information, so that there won't be conflict. Use GenSMBIOS utility or OCAuxiliaryTools for that.
Download mac os you want using macrecovery tool located at opencore package. Meanwhile you can start working on your USB.
create folder named: com.apple.recovery.boot. You can also copy the EFI folder from install folder onto your USB.
Once you finish downloading the macOS, check results folder, you grab all files called something like: "base_system" and place the into the com.apple.recovery.boot folder you created earlier.
Great work! Now reboot your machine and boot into your USB (F8 or F11 are boot keys that some system uses). You should see black screen with white text. Select option with .dmg as file extension. (could be named after your USB).
Here comes the crucial part of all this.
Your computer will try booting MacOS.
If you find any trouble, you have to google for solution. It everything goes well you should see installation window.
format your drive with APFS and install mac os.
Great! You have installed MacOS into your super RGB gaming machine, Steave jobs would be proud of you!
Now if you plug out your USB are reboot, nothing will happen(no boot), that is because MacOS is installed, but without bootloader.
To install opencore bootloader you will need this utility. Run it and select your system drive. Then just simply copy my EFI folder from postInstall into the EFI drive that you just mounted.
important udate your postInstall config.plist with changes that you've done to your installation config.plist
If all of this is done, then you can reboot your machine and boot to your freshly install mac os.
