impossible to install sequoia on my ryzentosh

[19MORPH69]

This is my first ever post on any forum so here goes.
SYSTEM M/B : Asus strix B550-A (Bios up to date)
CPU : Ryzen 9 5900x 12 core
GPU card. : AMD Radeon RX 5600 XT 6B
MEMMORY. : 56 GB 2666 MHz DDR4
OS. : Sonoma 14.7.5
My system works perfectly with little tweaks and I have a Sonoma USB installer handy to save the day. When I try to install Sequoia it never works. I choose "Install Sequoia " it stalls straight away (see photo when uploaded) and have tried everything for months since it came out.
Have read many different forum including this one and have tried everything suggested but no luck beginning to think my hardware even though it loves Sonoma just don't agree with Sequoia. Have even tried installing from software update and it spends about 1 hour 30 installing stuff to disk but on first reboot get exactly the same as in photo. So PLEASE if any one has any ideas cos on verge of giving up. I am not a novice (been doing this since Snow Leopard) but nor am I an expert so could be missing some thing dumb. Will up load my working Sonoma EFI and REMEMBER I have gone to many forums and guides and done a lot of reading. Never got head around DEBUG although OCAT is set to DEBUG. Forgot to mention my system has 2 Hard drives Windows on one and Sonoma on the other

Hello @19MORPH69 The first thing that stands out is you haven't updated the kernel patches that support Sequoia, the older version you are using is fine for Sonoma.

Tried the patches but still have the same problem unless I am doing something wrong but thank you for the help. Any help is much appreciated

Incorrect EFI setup:

1. OpenCore Release:
   1. You have elements in your EFI sub-folders that have different 'Date Modified' entries, this should never be the case for the BOOT, DRIVERS or TOOLS folder.
   2. This is a sure fire way to mess up your EFI and have your system fail to boot.
   3. The entries in these three folders plus the OpenCore.efi should all have the same date and time stamp, showing they all came from the same OpenCore Release.
2. Remove the APPLE folder from the Root of the EFI folder, this contains incorrect Firmware information that could cause issues when you make the changes recommended below.
3. ACPI Folder
   1. This is missing SSDT-EC.aml and SSDT-USBX.aml, both are essential for running macOS on an AMD system.
      1. You can use the Generic SSDT-EC-USBX.aml from Dortania or
      2. Generate your own using your system DSDT.aml and Corpnewt's SSDTTime script
   2. SSDT-CPUR.aml is for declaring the AMD Processor not for EC and USB power. This is essential for B550 AMD system.
4. Drivers Folder
   1. This is missing ResetNvramEntry.efi,
   2. This is required for clearing NVRAM after making changes to the EFI or config.plist
   3. Make sure you use the version of the driver from the OpenCore release you are using.
5. Kexts Folder
   1. You have a number of unnecessary kexts, which should be removed
      1. NullEthernet.kext
      2. RealtekRTL8111.kext (unless you have added a Realtek 1GB PCIe Ethernet card)
      3. SmallTreesIntel82576.kext, doesn't work with i225-V in recent macOS releases.
   2. You should add this kext to your OC Kexts folder and config.plist.
      1. AMFIPass.kext v1.4.1
6. Tools Folder
   1. Delete all Tools bar these three.
      1. CleanNvram.efi
      2. OpenShell.efi
      3. ResetSystem.efi
7. You are using the wrong SMBIOS for an AMD Hack which uses a discrete GPU.
   1. iMac19,1 is best used for a system which has a functioning/compatible Intel IGPU.
   2. You should use either iMacPro1,1 or MacPro7,1 SMBIOS with your X570 system.
   3. The iMacPro1,1 SMBIOS might give you better graphics compatibility.
8. Boot Arguments
   1. Remove -igfxvesa, as this is for a system with an Intel IGPU that requires the IGPU to be disabled and run in VESA mode.
   2. Add e1000=0, this should enable your Intel i225-V Ethernet in macOS.

This is a screenshot of your EFI folder contents:
Note the mis-matched Date Modified entries for the BOOT, DRIVERS, OpenCore.efi and TOOLS folder contents.

This is a screenshot of the EFI folder contents from my AMD TUF B550 Gaming / Ryzen 9 5900 / RX 5700 XT / Aquantia 10GB Ethernet / Broadcom WiFi/BT running macOS Sequoia 15.4.1.


Obviously as you don't have a 10GB Ethernet PCIe card or Broadcom WiFi/BT card, so there will be a few differences in the Kexts used by the two systems. But the Other folders should have nearly identical contents.

The exception to this is I need an SSDT-Bridge.aml table for my RX 5700 XT GPU to be recognised correctly by macOS.
You might need a similar SSDT for your RX 5600 XT but you will only know that once you have macOS installed and check the IOReg Name for your dGPU.

Make the changes recommended above and see how you get on.

Tried all you suggested but still hitting the same pointy more help greatly appreciated

 

[Edhawk]

Where is the rest of the NVRAM section from your config.plist? Most of the NVRAM sections is missing, Arbitrarily removing sections of the config.plist without knowing what that will do is not advisable.

 

[19MORPH69]

have to admit never edited nvram section except to change the odd boot arg

 

[Edhawk]

This is how your NVRAM section is configured. Red rectangle shows extent of the section.



This is the NVRAM section from my Asus B550 system. Huge difference.



Also there is little point using the Debug version of OpenCore if you don't implement any debug logging.

If you change Debug > Target > 3 to 67, your system will generate an OpenCore log file (located on the root of the EFI partition on your macOS installation drive) from each boot session, which might show what is causing your system to Kernel Panic.

 

[19MORPH69]

Right I hope this helps any one clever enough to sort out my problem.Set Debug target from 3 to 67 and got the attached file. Also can add that the EFI file does allow Sonoma to work without fault so REALLY hope some one can solve it

 

[Shaneee]

You've not used the debug version of OC and your NVRAM was still wrong. Here is a fixed DEBUG version of your EFI that'll log it all to file.

 

[19MORPH69]

Here is the OpenCore file I get when using the EFI file you sent.Hope it helps

Used your EFI file and produced a log file but it beyond me what I looking at

 

[19MORPH69]

Just to add the debug EFI on the sequoia usb installer loads sonoma without any problems but when trying to install sequoia it sticks in the same position ( see post 1 photo) so still missing something and remember if update within sonoma update downloads and starts installing but on first reboot sticks in same place

 

[19MORPH69]

hope somebody still reading this as I have made progress. Will attach photo and up to date EFI and debug file

 

[19MORPH69]

The top 2 lines (starting with 31) seem to correspond with the last couple of lines of the debug file but not know how to fix. PLEASE help if can I’m starting to get somewhere
Thanks in advance

 

[19MORPH69]

On closer inspection my current problem seems to stem from the few lines in the open core txt file that start with “31” and correspond with the last few lines on screen but don’t know how to fix

These two lines are related to the OpenCore theme you are using. The theme is missing a few icons, this has nothing to do with your system failing to boot the macOS installer. They are not pointing to a kernel panic.

The two ‘31’ lines are a red herring, you need to ignore them and keep looking for the reason why your hack doesn’t work.

 

[19MORPH69]

Finally got there thanks to those that helped. The final problem was very easy to solve in the end and it was to simply put the USB installer into a different
USB socket. Because it was new install the USB mapping needed re-doing which is now all done and SEQUOIA is up and running smoothly.
So, again thank you to those that pointed out where I had gone wrong you helped tremendously
