Actually I've just done some further research online for you on VRR. As it goes some sites say there is VRR support while on Apple Support itself they say that there is no VRR support in macOS (but your reply on the issue with the Mac Studio says otherwise). So I've read if you experience...

Which CPU do you have installed? If yours is different from the OP's build you have to adjust for the CPU core count under Kernel > Patches.

I honestly think this is probably your only chance to see if it works for your laptop, because I couldn't find anything on it named Samsung other than for the AMD chip > https://www.notebookcheck.net/AMD-A-Series-A6-4400M-Notebook-Processor.71726.0.html It's based on AMD Bulldozer so it should...

You can alter the EFI to fit your needs. Follow the guide here to alter your core count to 2 in the EFI/OC/config.plist:

Yes all is required. As for the rest, did you add agdpmod=pikera in the NVRAM boot-arg?

To be honest I think your model of laptop based on the CPU is too old to run macOS. Anything beyond 7 years is now really pushing it. I could send you the link for an EFI based on my AMD Ryzen 9 B550 build which you could try that may work with High Sierra, but you’ll need to modify the Kernel >...

Is your AMD dGPU device properties PCIRoot tree populated? If not then may need the following. Here I use the RX6800 but you will need model set to RX 6900 XT instead as well as the key no-gfx-spoof with value set to 01000000 and type set to DATA. Reason for that is your 6950XT only works fully...

Which version of Monterey are you running and have you enabled any of the AMD power management kexts such as AMDRyzenCPUPowermanagement.kext and SMCAMDProcessor.kext?

You can try my EFI build here, but you will need to change the core count to 6 and also upgrade it to OC 0.8.4 for it to work with Ventura

Thanks for the concern, but it’s been since sorted (I had spoken with the mods).

You shouldn't disable SSDT-EC or SSDT-EC-USBX. That's a vital component for Opencore to run. I'd also suggest you get a copy of SSDT-UIAC.aml and include it as part of SSDT-USBX.aml. With these two installed, just try enabling USBInjectAll only and see what ports comes up in the system. Try...

Do you have the SSDT-EC-USBX.aml or SSDT-UIAC also installed?

Okay. In that case you are running Catalina, you may need to revert to the itlwm.kext version.

Have you tried checking the USB ports with Hackintool?

To set up the BT and wireless it’s quite easy. For Intel BT you’d need Bluetoolfixup.kext and IntelBluetoothFirmware.kext. For wireless use Airportitlwm.kext stable version from the OpenIntelWireless Github. Reboot with ResetNVRAM if your EFI has issues.

Did you follow the Dortania guide here? It shows you everything you need to know to create the installer For the com.apple.recovery.boot you are supposed to create that folder in the USB once the files were extracted to it and then move both BaseSystem files into that. For the kexts, you can...

You can disable GPUs two ways. One is to use either the -wegnoigpu setting (for internal cards) or -wegnoegpu (for external cards) under NVRAM as a boot-arg OR use a SSDT-Disable-DGPU.aml in your EFI/OC/ACPI folder with the PCI path defined from say your Windows/Linux hardware device settings...

Not sure if you know but USBToolbox.kext also requires the use of UTBMap.kext loaded afterwards to work. On top of that for AMD setups you may need a PTXH or XHC rename SSDT for the USB to work. Check out CaseySJ’s guides on Ryzen setups for this.

Okay. See if adding VoodooInput.kext above those kexts also help? If not try this next one - in some configurations I've seen some laptops needed the files like this: VoodooInput VoodooI2C VoodooI2CElan VoodooPS2Controller

You could maybe have a look at this fix if it hasn't been done already > https://github.com/mikigal/ryzen-hackintosh/blob/master/README.MD#mkl-and-intel-fast-memset-patch
