if you have a Mac Pro 4.1 you have to verify some things in it

It is possible to use an apple firmware to flash it to latest 144.0.0.0.0 boot rom and use also OSX like sonoma (using OCLP)

Have you any OS yet installed?

if so verify here:

this is from my hack (later i will post the same thing i have in my mac pro 4.1/5.1

It is a simple procedure to do, a bit tricky but it is possible alo with a poor experience in this field (as me i mean)

Then, ye it is possible to boot and also see boot menu using your RX580, and it is also possible to flash the firmware with it

for more detailed instructions check this:

EDIT

Mac Pro 4.1 data

this below are the value that OCLP spoof/inject:

as you can see i have also update the xeon to a 6 cores xeons (Mac Pro 5.1)

this original data after installing Mojave 10.14.4

installing latest Mojave will upgrade the firmware to 144.0.0.0.0

from there you can update till latest macOS Sonoma using OCLP

i stopped my system to Monterey because i have installed a RX 6600 GPU whic OCLP supprts by now only in Monterey

your RX 580 works also in Sonoma

There is a script which help to patch apps not compatible with amd due MKL libraries

Here some informations

Hi Jungs,

Hat von Euch jemand das System schon mit Ventura oder Sonoma am laufen?

Hi

I have installed Sonoma 14.1.1 with OCLP on a Mac Pro 3.1

I use an original 5770 hd GPU

the only problem i see is the lack of wifi and bt support

In a 5.1 MacPro it seems all is working with the same GPU

all is fine with AMD CPUs

Gabse i am sorry, i will usw deepl to translate in german language

Virtual Box läuft sowohl unter Windos als auch unter OSX reibungslos (das obige Bild wurde unter OSX aufgenommen und zeigt eine Reihe von gleichzeitig gestarteten VMs)

Je nach dem System, das Sie virtualisieren möchten, müssen Sie bestimmte Befehle eingeben

um zum Beispiel Tiger zu starten:

New release on regular seed

Nächstes Problem wird das Mikrofon sein

if you use internal audio will not work

you need an usb audio device to have a microphone working under OSX with many AMD motherboard

It doesn't work.

this doesnt help to understand.always it is important to have more informations where the system hangs

Previous EFI i did is like the same EFI (updated) from your first success posted here to boot in OSX

So i can say problem could be of two types

1) you are booting from a different EFI and not the one we are tryng to set

2) Bios settings

there is also another option like different hardware added in the system or hardware failure (latest option is not. a real option but it could be also usefull to debug)

Please check this three options in your motherboard bios:

CSM support set it to Disabled

Above 4g Decodig set it to Enable

Serial port configuration set to disable

then use this EFI

In Opencore boot menu press space and reset Nvram

then cross finger

I would try to disable secure boot from first screen shot

Reset nvram after this modify

check in your bios serial port configuration option and disable it

Same thing happens on my machine on 14.1 Beta 3 (23B5067a) as well as 23B73

- instant crash of the preview.app - it does work with .ai files tho but crashes with all other pixel image files.

Manually selecting "export as pdf" is a work-around for now.

this bug is solved in 14.2 beta (23C5030f)

Dr-C beautifull Apple!!
I am Joking

that error could be USB related..but also for other reasons than an Apple could not easily reveal

Before clicking on Mackintosh HD

press ⌘ + v to see verbose mode

and check if you see errors on this (post a video as before)

Kext and opencore are not udated, but if you didnt update OSX EFi should work well

Check if in your BIOS Above 4G option is enabled or not and post a phot o where the boot hangs

A step forward🥹

Check if all bios option are set fine as we did in the past

If you can post boot and oc folder in a zip file to see if they are fine

I wouldn’t touch nothing with bootice

I would try to choose disk from bios to boot if you have adjusted Efi partition as I see in last your pictures

Now the Efi structure is fine

I can’t say if inside boot and oc folders there are the right files

EFI structure posted above is wrong for OSX (a nested EFI in other EFi folder)

Opencore can't boot in this way
