I thought i was clear with you in this thing

Hello fabiosun,
please can you tell me which of these kexts are not mandatory and should be disabled?
Thank You.
these in blu:
when you update with success you can enable them again
-
SecureBootModel from Default to Disabled (if you have a bootloop) others Config.plist parts are fine (you can disable many not mandatory kext to install, but SecureBootModel should be enough to set as i said to have success)
-
-
In sonoma (with AMD CPU) you have to disable Secureboot (if you have on Default set it to disable), then download again the update if you are using a delta update to upgrade your Ventura OS
-
if you are installing from scratch, try to disable borh Visual Kernel patches (not useful for your rig)

kannst du mir beim Patchen Helfen bitte hab Big sur drauf kriege Sonoma nicht yum laufen Die Installation bricht immer wieder ab ...
From Big Sur to Sonoma is a big jump
First you have to update Opencore , Kext and kernel patches
Otherwise no joy

Deine GPU RADEON 6650 XT benötigt mit SMBIOS iMacPro1,1 den boot-arg: agdpmod=pikera
rx 6650 is only supported using a GPU spoof to rx 6600 (like ie rx 6950 need a 6900 xt spoof)
or use NootRX kext without using Whatevergreen kext and its bootarg
i prefer to spoof and use WEG and pikera bootarg
-
meanwhile if you like to try this EFI, before backup yours
If your system starts, then you have to spoof your 6650 gpu
a step at time
check also suggested link to see bios options you need to set
-
aedm you need a kext and a bootarg to have your Ethernet working:
AppleIntelI210Ethernet.kext.zip
then:
in short you have to use and put an old OSX ethernet kext and e1000=0 in your config.plist proper section
if yiu are lucky your ethernet will work only with these two modifies
If it is not working you may have the need to spoof your ethernt card to a supported one (some motherboards need of this)
EDIT
As said by greecedrummer user Ethernet is not an Intel (so all my assertions could be deleted)

Habe ich auch schon gesehen funktioniert aber nicht mit einer 6650xt bekomme dort einen Fehler. Daher habe ich diese Methode schon zu den Akten gelegt
you have to read in that thread
you have to flash before a compatible 6600 firmware for your ASUS 6650 xt GPU, then you can patch it as explained (and then use Opencore for boot menu)
NootRx is unrelated for this user request

@
Dankeschön. Dann habe ich jetzt 2 Möglichkeiten am Samstag was zu probieren.
You are trying to install this GPU on a real Mac Pro 3.1
You have to flash your GPU with a little tool you can find in mac rumors forum
Without it no screen for rx6600/6650 gpu on a real mac
then, if you succeed to this task you can install OSX Monterey (this is a limitation for old Mac Pro 3,1,4,1,5,1 computer because their CPU lack of some important instructions)
If you succeed in these two task, you can use your GPU using kext quoted above or only spoofing your gpu to a 6600 one (you can do this in your Device Properties) config.plist section)
* you need a GPU cable from mac motherboard to GPU (2 mini 6 pin to 8 pin)

macOS Sonoma - 14.4 beta 4 build 23E5205c
Full Installer
-
Save in a safe place this efi
Now you have to add other kexts you need
edit secure boot model default -
At first the apple logo with an loading screen and then this picture with the Blackscreen.
for second and forth icon?
could you try another GPU port? hdmi/dp?
edit
added a new config.plist
reset nvram when you see boot menu before you try your macOS disk or usb installer
edit2
added a second config.plist
this one has verbose mode on
take a video before black screen happen
-
And selcting white apple (it should be your usb instalerr) or macOS icon (your OSX disk) what happen?
