Hi and thanks in advance.
I'm having some trouble, sorry if this a silly question, but how can I enable ProvideCurrentCpuInfo? I can't find it in config.plist

Any help please

Make sure you are using OpenCore 0.7.2 and the quirk will be there.
Kernel->Quirks->ProvideCurrentCpuInfo

Thanks for your reply.
now the installer starts and then I get black screen!
EDIT:
I'v managed to install Monterey successfully, I used latest version of WhateverGreen and Lilu and installation finished as expected!

This is laid out in the AMD_Vanilla GitHub Readme but I'd thought I'd post here too incase of any questions.

Patches are now universal across 15h, 16h, 17h and 19h by utilising the OpenCore Kernel Quirk ProvideCurrentCpuInfo

Make sure to enable this quirk or the system won't boot.

This quirks provides the kernel with the CPU frequencies for macOS to boot.

Core Count patch needs modified to boot your system. Find the three algrey - Force cpuid_cores_per_package patches and alter the Replace value only.

Replace:

B8000000 0000
BA000000 0000
BA000000 0090

Becomes:

B8 <CoreCount> 0000 0000
BA <CoreCount> 0000 0000
BA <CoreCount> 0000 0090

substituting <CoreCount> with the hexadecimal value matching your physical core count.

Note: The three different values reflect the patch for different versions of macOS. Be sure to change all three if you boot macOS 10.13 to macOS 12

See the table below for the values matching your CPU Core Count.

CoreCount	Hexadecimal
6 Core	06
8 Core	08
12 Core	0C
16 Core	10
32 Core	20

So for example a 6 Core 5600X Replace value would result in these replace values

Replace:

B8 06 0000 0000
BA 06 0000 0000
BA 06 0000 0090

Note the 06 for the 6 Core CPU.

It's quite simple but if you've any questions on how to do this simply ask.

Enjoy,
Shaneee

Please tell what file (s) should I edit, where and how can I find algrey - Force and the others. Thanks

It's the first three patches in the plist.

I already use your entire EFI, modified with my MMIO and platform info, but doesn't work.
After reboot, install freezes at almost 3 percent, the computer only responds at forced shutdown...

Are you referring to the black screen with the Apple Logo and progress bar when you say 3 percent?

What is the hexidecimal for 24 core threadripper?

 

[Aluveitie]

0x18

Open Calculator, switch it to Programmer mode (⌘ + 3), select "10", type 24, switch to "16" to get the hexadecimal value.

It's the first three patches in the plist.

I don't have these entries in my p.list, unless I am looking in the wrong area, as the first patches listed do not mention cpu anything . I'm on Big Sur at the moment (11.6.3), and have checked the option ProvideCurrentCpuinfo is active. Is there a specific area to look for these Algrey entries?

I've made an edit including my p.list.

I just downloaded your p.list for the Asus board (I am using an Aorus x570 and 3700x), and looking for the entries mentioned in this thread, I do not see the data you mentioned that should be either altered or outlined in the 'Force cpuid' sections of your p.list .

 

[Shaneee]

See here,

yes, using binary did the trick on yours, but mine is not going to fly in its present state. It looks like I will have to start from scratch...

Ah so your editor is showing it in Base64. Just convert from hex into base64, https://base64.guru/converter/encode/hex
