Sequoia installation troubles on an AMD 9 / RX580

[GrisOlle]

Greetings!
Running into some problems installing Sequoia 15.7.7. on the following system

Motherboard: MSI Pro B650-a WiFi,
CPU: AMD Ryzen 9 - 7900X,
GFX1: //Temporarily Disconnected// GeForce rtx 5060ti 16gbvram (epci1 - Windows/Linux),
GFX2: Radeon Rx 580 series 8gbvram (epci2 - hackintosh),
RAM: 32Gb DDR5
PS: Corsair rm850e
SSD1: //Temporarily Disconnected// Lexar Area pro 1Tb (m2.1 - windows)
SSD2: //Temporarily Disconnected// Fangxian 256gb (m2.2 - Linux)
SSD3: Lite-on LGT128 m6g (m2.3 - hackintosh hopefully)

Currently I only have the Radeon and the SSD in m2.3 connected for the purpouse of installation. Monitor is connected via displayport on the Radeon RX580.
I´ve created the USB using OpenCore Legacy patcher 2.4.1 (I have very slow internet connection atm so I need to download the image offsite and copy)
Below is the config file I´ve taken from the post kindly suggested by @Edhawk and edited with information that i could find regarding this setup
I´ve tried to clean up the kext to get it to install however it freezes up on me and I can´t undertand where the error is.

I have some doubts, is it correct that the UTBMap.kext has a maximum of 16 ports (I´ve disabled 3 as it discovered 17)?

is this correct:

-v keepsyms=1 debug=0x100 agdpmod=pikera npci=0x3000

This is where the installation stops

Having the RX580 hanging from the chipset rather than the CPU is not optimal. I'm afraid that a dual or triple boot with alternative GPUs will be difficult, unless you can find a motherboard with a pair of x8/x8 bifurcated PCIe slots from the CPU.

I know none of your SSDs, and have no idea whether any is suitable for macOS, which is picky.

I have some doubts, is it correct that the UTBMap.kext has a maximum of 16 ports (I´ve disabled 3 as it discovered 17)?

No. The limit is 15, but it applies per controller; as AMD systems have multiple USB controllers you may well have more than 15 ports in total.
How have you done USB mapping? In doubt, use a USB 2.0 port and/or device.

-v keepsyms=1 debug=0x100 agdpmod=pikera npci=0x3000

agdpmod=pikera is for Navi cards (RX 5000, 6000), your RX580 does not need it.
npcie=0x3000 maybe, but why?

No SSDT-CPUR, or equivalent (PLUG-ALT)? That's not going to work.

 

[Edhawk]

AMD systems need to enable ‘Above 4G Decoding’ bios option or add the ‘npci=0x3000’ boot argument, if the bios option can’t be found.

Never both at the same time.

 

[Edhawk]

The proposed Lite-on SSD is a SATA/AHCI drive not NVME, so it may be OK as the macOS drive.

The Fangxian NVME drive is fine as a secondary drive, I.e. containing a different OS, not as a macOS drive. I know this from experience using a similar drive in a dual boot Dell system.

I’ve never used a Lexar Ares Pro PCIe 5.0 drive, but doubt it would play well with macOS. It may be OK as the Windows drive but only time will tell when it is reconnected and the OP tries to triple boot their system.

How have you done USB mapping? In doubt, use a USB 2.0 port and/or device.

I inserted my windows SSD and used USBToolBox. I´ll try with usb 2.0

No SSDT-CPUR,

added the SSDT-CPUR

enable ‘Above 4G Decoding’ bios option

would it be the same to disabled the 4G Decoding and keep npci=0x3000?

Will give this a go next time and see what happens
(hoping I can post in the success stories soon!)

 

[GrisOlle]

I had a chance to try out advice from @Edhawk and @etorix (cheers!). I added back the SSDT-CPUR and some of the kext I belive are needed for this system.
However even after resetting NVRAM I'm still not able to install

Could it be due to some incompatible kext?
Do I need to add anyhing in the boot-args?

-v keepsyms=1 debug=0x100 slide=0

config.plist and log file attached below

 

[Edhawk]

What verbose text is shown on the screen when you try to boot the system to the macOS Installer? Post a photo of the text (whole screen) so we have a better idea of what is causing the kernel panic.

 

[Edhawk]

You would be best served using the above 4G Decoding bios option and deleting the boot argument. That is my experience with a similar system.

Here is a screenshot showing how I have setup my OpenCore EFI folder for my B650E-F Gaming system. It displays all the kexts, SSDT's, Drivers etc.

OC EFI folder contains viewed in Finder.

See if anything stands out as being obviously different in your setup.

I would confirm the following:

1. All the SSDT's were generated using Corpnewt's SSDTTime and the system ACPI tables in a Windows installation on the B650E system.
2. I am using OCLP v2.4.1 on this system to get the Broadcom WiFi working in Sequoia.
3. NootRX.kext is used to support my RX 6700 XT dGPU.
4. The USBPorts.kext was created using Hackintool, but it was based on a UTBMap.kext that I initially generated while running Windows 11. The USBPorts.kext was created because I was looking to install Tahoe on a separate drive/partition. So as UTBMap doesn't support Tahoe I used Hackintool v4.1.4 in Sequoia to generate/export a Tahoe compatible USB kext.
