Z690 Chipset Motherboards and Alder Lake CPU

Hyper threading has just been turned off in the BIOS, and now it normally enters the installation interface, but the page has only one mouse pointer.

You're going fast… I saw no DMAC device and no DMAR table in the two sets of ACPI tables that were published so far. Is it also the case for your board?

I see VoodooTSCSync attached to the last CPU. Had you issues with TSC?
Processors are at addresses @0, 8, 10, 18, 20, 28 (so far, so regular), 38, 3A, 3C, 3E. If you're still on 6P+4E, the last four should be the E-cores: More tightly packed, but why do they start at 0x38, which would be the last P-core address for a CPU with 8 P-cores (as seen earlier on Gigabyte Z690 Gaming X)?

OK, I've just been working overtime for a little while. I've uploaded it. Thank you

Thanks! I saw no reason to adapt the SSDTs to your board: Always the same processors, clocks, EC, system bus, MC.
On the first three attempts you had all cores and hyperthreading, which is known not to work. The fourth (8P+8E, no HT?) should have been fine.

Now the interface is stuck here. The CPU counterfeit code is 55060a00. Is it counterfeit or wrong? The model is MAC pro7, 1. Is it because my motherboard is ddr5 memory, so I can't support installation?

This CPU spoof worked for other users.
I only see the end of the trace of the panic, with IOPCIFamily. What was above?
An issue with PCI could point to an unsupported device: A SSD, or the RX550. Is the RX 550 known to be a Polaris card, working with OS X, and not a Lexa?

No it isn't because of the DDR5 nor because of the MacPro7,1. It is because you are running a still very much experimental build of Opencore (because 12th gen Alder Lake is so new). If I'm not mistaken, VirtualSMC and various parts of Opencore is currently being rewritten as we speak by Opencore dev team for Alder Lake support.

However with the correct (appropriate) settings it should still run. SSDT-CPUR-Z690.aml needs to run first (top of the list), along with SSDT-AWAC.aml and SSDT-EC.aml and SSDT-PLUG.aml at bare minimum.

Anyways your CPUID1Data should be:

Code:

55060A00 00000000 00000000 00000000

and your CPUID1Mask should be:

Code:

FFFFFFFF 00000000 00000000 00000000

Min kernel: 20.0

AppleXcpmCfgLock: enabled

You must also have SSDT-CPU-WRAP and SSDT-PLUG.aml copied over from the version .4 EFI build.

And also turn off hyperthreading in the BIOS.

Gigabyte Z690 Aero G has a DMAR table, but no DMAC device in DSDT.

I enabled CpuTscSync.kext to see whether it might cure the issue with 2nd wake-from-sleep cycle. But alas it does not solve that particular problem.

If you using a wired mouse or keyboard, and there's an LED on one or both of them, see if the LED is still on. USB ports might be dead.

SSDT-CPUR is the same as SSDT-CPU-WRAP: Different name, same function. (@metacollin used the name CPU-WRAP when he identified the issue with a C621 board, the name has stuck with HEDT users. Acidanthera used CPUR —"redefine" or "rename" I suppose—for AMD B550 and A520.)
It only need to load before SSDT-PLUG, which depends on it. The rest does not matter.

A quick update on Maple Ridge:

On RP05 we have to disable both HRUS and PXSX, so I made the change for PXSX.
Now the proper device names appear.
USB-C devices can connect both at boot and hot plug.
Thunderbolt devices do not connect at boot or hot plug.
This is with both 5-pin and 3-pin Thunderbolt header cables plugged in.
- Will try 5-pin alone, then 3-pin alone.
Attached is latest version of SSDT-MAPLE-RIDGE-V1.aml
I will check Thunderbolt functionality without SSDT, then try the simple SSDT that only changes Device ID.

this is the same error I was also mentioning previously. I tried to install EFI into the system disk then tried to boot into recovery partition but no joy. I am getting the same screen.

You may need to spoof Comet Lake IGPU and AAPL,ig-platform-id also for it to work. ie. 00009BC5 and 9BC50000.
If you are using an AMD dGPU, you should also enable it with agdpmod=pikera in boot-args (if it helps).
