Unsupported devices and some boot errors I don't khow?

[techtuong]

Umm, recently I try to install macos on my Lenovo Ideapad Slim 3 and when I check the compatibility of my laptop and I get this...


May I ask is it the reason why I got this when I boot up the mac recovery and try to install mac os:

And if it does, can I ask for a solution? Any extra information needed, please ask below, thank you a lot!

You appear to have a problem with GenericUSBXHCI.kext, a parameter is set incorrectly according to the second image above. You probably have other issues in your OC EFI folder, which aren’t defined in the screen image.

The first image is fairly normal for a Windows laptop that contains incompatible components.

So is there any solution available now, sir?

Yes, you can replace the incompatible Realtek WiFi/BT card with an Intel or Broadcom card.

Each brand of supported WiFi/BT card requires different kexts and config.plist entries to get them working in macOS. Plus the internal USB port connecting the Bluetooth device needs to be activated and set with the correct connector type.

You can use a USB to Ethernet adapter in place of your Realtek Ethernet device. One like the adapter shown below would work without the need for any additional kexts etc.

I am not sure what you have done to have the GenericUSBXHCI error show.

If you obtained your OC EFI folder from someone’s GitHub repository you may want to see how they got around these issues and if you need to adapt the EFI for your current setup.

Thanks you, sir. The unsupported devices problem is okay now. The EFI folder I get it from the OpCore-Simplify, in the OC/Kexts folder, I replace the USBToolBox.kext and insert a UTBMap.kext generated from USBToolBox tool to do USB mapping. I will try to look into the github and try to find something useful.
