Also confirm the following:

1. The version of macOS you are trying to install, I.e. Monterey, Ventura 13.6.x or Sonoma 14.3.1 or 14.4.1
2. The make and model of the M.2 drive you are using as the macOS drive.
3. The make and model of the WiFi/BT card installed in the laptop.

I am installing Ventura 13.6
My m2 drive Crucial P3 Plus 1TB PCIe Gen4 3D NAND NVMe M.2 SSD,
The wifi card I am using is an Intel wireless network card.
Would you kindly help me to check with my new issue with the efi you provided if you have time? Thank you

Which issue? You need to be a bit more precise with your requests.

Where are you with regards installing and running macOS on your Legion Slim 7 Gen 7 laptop?

How have you set the Graphics in your system Bios, have you used the MUX switch to set the AMD Radeon RX 6600s as the main GPU, i.e. turned off the AMD Integrated GPU?

Would you kindly help me to check with my current issue on your provided EFI?(get a forbidden icon after IOUSBhostdevice configure). Thank you

Have you tried using every USB port on your laptop for the USB installer?

Have you tried using every USB port on your laptop for the USB installer?

Thanks for your reply,I think I have tried every USB port on the laptop but the issue is still the same

Some AMD laptop owners had to resort to using GenericUSBXHCI.kext to fix not being able to use their USB ports. This is an old USB kext, which was dropped from use on Intel systems some years ago. So not sure it will work, but may be worth a try to see if one or more USB ports are enabled so you can complete the macOS installation.

I can't recall if you have created a UTBMap.kext in Windows, using the USBToolBox python script. If not you may want to see if doing so helps. This is an alternative and better option than using the GenericUSBXHCI.kext.

Thanks for your reply, I will create UTBMap.kext in linux to see whether it works.

Using the old version of GenericUSBXHCI.kext seems not working. It would get a forbidden icon SMCProcessorAMD. Next I will try generating UTBMap.kext to see whether it works

 

[Edhawk]

The SMCProcessorAMD isn’t a Kernel Panic, the issue is the USB port you are using.

When you see the forbidden icon, or preferably when you first see the SMCProcessorAMD text, try switching the USB installer to another USB port, do this quickly and see if the installation continues. Sometimes a USB port that works from the power on of the system will be dropped when the Bios hands over control to the Bootloader/OS.

I had this happen on a couple of AMD hacks, if you are fast enough with the port switch, the install continues.

I have tried switching USB port after SMCprocessorAMD text, but it still gets a forbidden icon, you can merely see a text showing USBSMC identifier non-unique

I have also tried using USBToolbox.kext and UTBMap.kext. But the USBSMC indentifier non-unique issue still exists. I changed UTBMap.kext to UTBDefault.kext, but the issue is still the same.

Try disabling the Bluetooth kexts, just while you are trying to install macOS, as it appears from the image above that the Bluetooth device is failing to activate. The Bluetooth module uses a USB port, which may be part of the forbidden sign issue.

Not sure how many external USB ports are present on the laptop, but you may need to move the USB Installer drive to another port when you start the laptop and macOS installation.

After disabling Bluetooth kext, the USBSMC identifier non-unique issue still exists. There are 2 usb ports in total on my laptop. I have tried moving the usb installer to another port before the forbidden sign. But the issue still exists

I also found a Hackintosh version which has a very similar configuration with my laptop (5800H+6600m vs mine 6800H+6600m).

This one is using GenericUSBXHCI.kext. However as the USB configuration is different. The ACPI folder may need some modifications. Would you help me modify the EFI using my DSDT? Thank you.

 

[Edhawk]

Post a copy of the current EFI you are using, As I don't want to start changing the wrong EFI folder.

 

[innocentrose]

i am in a similar situation to redhorse1990 i have a Legion 7 Gen 7 AMD Advantage Edition (Not Slim Version) laptop. Its specs are 6800h and 6700m.
I faced similar problems to redhorse1990, i came across a tool called Smokeless_UMAF with which we can load advanced bios and disable our extra USB ports. Do you think we should go down that path ?? and would you guide me on which ports to disable ??

Try to disable SSDT-USB-Reset.aml and use GenericUSBXHCI.kext .

looks like somebody succeeded in making a hackintosh of a laptop identical to you. Their post on reddit. Just bear in mind they have disabled nvme which you might have to enable by removing the boot argument

Almost right , except for this one. I think this is because of the changed ACPI mapping after NVME is added. Would you help me make some changes to fix it? Thank you
I have tried changing the USBMap.kext to UTBMap.kext that is created from USB toolbox and using XHC1 to XHC_ rename patch in plist. But the issue is still the same. And I also tried changing ACPI file to your created one using my USB configuration. And the issue is also the same.

Anyone has success story on this model?

Anyone has success story on this model?

I've been cranking on this for a few days now, with no luck. I have the exact same model as innocentrose
