Ahhh, ok that makes sense… I appreciate the break down. I am still learning. So if I understand this correctly, I should remove the DDST.aml amd use SSDT-Plug etc to fix shut down issues? (I have an asrock mobo that don’t shut down, it reboots, even with usbtoolbox.) Odd thing is it sleeps and...

No... I did not patch the DSDT. I have to go out of town and wont be back till monday so I will correct that.

On this EFI I cannot boot past this…

here is the Hackintool PCIE Export...

OK this is the dump from IOREG booting from the EFI with your kext... Note this is still on Big Sur 11.6.2 so the AX210 wireless and bluetooth will not work so dont know if that will cause any issues. I am about to erase and install an older Big Sur that was supplied by EdHawk to bypass the...

Is this kext to be used with USBToolbox.kext or by itself?

Ok, I will try these tomorrow… Edhawk, on your usbmap2.kext, should I try it with the efi that functions the best?

When creating custom DDSTs for our machines, I have a couple questions; 1. What is recommended route to create a DDST using SSDTTIME? For example, I bypassed OPENCORE altogether and boot from the windows EFI and then create my DDST dump in windows. My line of thinking would be that this would...

There are 6 external, (2 are USB-C) In the meantime, I created a DDST out of SSDTTIME and remade my usb. port mappings using USB toolbox in Windows. Now when I boot into 11.6.2 it freezes at the following.... wondering if I missed something, I have UTMap.kext and USBToolbox.kext installed.

I am about to reformat and install using a modified EFI that I made starting from zxc2689963's EFI.... His so far responds the best in Big sur and the USB ports work, it just does not have proper wireless (using realtek nic for now) nor sound. I am not too worried about those things yet, I just...

The bios of this does not have an Above 4G decoding, but on Shaneees he does not have the npci=02000 boot arg, but he also chose the ImacPro1,1 symbios. So far zxc2689963's EFI from post #98 responds the most under Big Sur.... I am working on making the Installer for the older version of Big...

Shaneee's EFI got me into Big Sur that I already installed V. 11.6.5, however the usb mouse and keyboard are VERY laggy, pretty much unusable BUT does boot into mac os Big Sur... On yours middleman, it starts to boot but hangs right where it switches from verbose logging into the apple loading...

I didn't forget about everybody, I am trying to get the older version of Big Sur downloaded to get installed...

On my legion I had to do the following; Graphics Mux: Discrete AMD V: Disabled Always On USB: Disabled AMD Platform Security: Disabled Secure Boot: Disabled

The earliest version I see on anymacos is 11.5, if that will not work then I would appreciate the link! As for keyboard, it is working with supplied EFI but the trackpad is not, I am using wireless keyboard and mouse. If you cam get that EFI by monday I will try getting a dump with that one as...

Ahhh…. Ok,that is the original usbports kext that came with the efi from post 98. I made a port map with usbtoolbox, I will swap to that one and will install an early version of Big Sur to get a better dump…. I will try it with both efis from shaneee and middleman as well. Won’t be able to do...

OK.... I want to create reinstall Big Sur and make a clean IOREG dump from there. If I understand it correctly, zxc2689963's EFI boots into Big Sur and all the USBs work, but not video (RX 6600m). So the attached EFI is a copy of his EFI that runs Big Sur. I removed some drivers not needed in an...

Yeah, the usb c is usb 3.2 gen 2

I won’t be back in front of the laptop until Friday, we are moving furniture around at home and laptop is at work so will try efi and suggested fixes friday

Yes, this is the EFI I am currently using.... I also included the EFI we used to install big sur. (I did not do the port mappings with it, but I will try the suggestions that you suggested. Do you think I should change the symbios to the MBP 16,4 when I reinstall Big Sur?
