Ahh there! Yes, it all makes sense then: seeing "Pitcairn" as the framebuffer is a sure sign that macOS is not using AMDRadeonX4000.kext, but something else — probably a broken fallback or a bad match from AMDRadeonX5000Controller. Monterey sees your device-id 0x682B, but it doesn't load the right kext (X4000) because of the policy. Instead it tries to handle it with a wrong framebuffer, like Pitcairn, which is not compatible. Result: no acceleration, black screens, or only VESA mode. config.plist2 we force the kext 7000 and 4000controller and patch them try config 2.plist.zip

@naquaada macOS Monterey disables GCN 1.0 support via policy, even if the ID is present. Some IDs (like 0x682B) remain in the plist for historical reasons or internal backwards compatibility, but: AMDRadeonX4000.kext drivers are not loaded. Even if the kext is present, matching fails at runtime. This also applies to 7000Controller.kext, which does not contain Oland-compatible framebuffers, so even if it "sees" the ID, it is of no use. Great point! Yes, it's true: the ID 0x682B (i.e. your RX 250) is present in both: AMDRadeonX4000.kext ➜ legacy GCN 1.0 drivers (Oland, Cape Verde) AMDRadeonX5000.kext / X7000Controller.kext - used for newer models, but sometimes with leftover support - But be careful: being listed in kexts does not mean they are actually loaded! Check with gpuid if your card has Uefi support or if it needs to be flashed, try my config.plist, I put a more compatible framebuffer in the devices proprierties "Futomaki", but you can also try Hamachi, remove the no_comact_check from the boot arg and still keep your config working configOlandXT.plist.zip

Open config.plist with OpenCore Configurator or ProperTree and set: Misc -> Security -> Vault = Optional

add inside the driver folder, it is already declared in the config.plist HfsPlus.efi.zip

this is a base to work on, IGPU is disabled and ATI too, then after you will work to make it work, create an installer with BIG or Monterey, mount the efi partition and insert the EFI. I advise you to disconnect the disks where you have the system working with Clover it could conflict, so either use OC or clover EFI 2.zip

I repeat, try to make a BigSur USB, and put OpenCore as boot loader, using only basic kext lilu, virtualSMC AppleALC and WhateverGreen, do not use DSDT, in the ACPI folder put only SSDT-Basic that you find in Download, you will see that with some care and patience we will install it, of course we use an independent HDisk without compromising your working one

I think that from opencore you can still disable the igpu and try to run the ati 6200 with OCLP

let's do one at a time, tell me exactly which one you want to update and if the bios is legacy or uefi, you see I have systems with bios and x58 and 775 cob on big sur, Ventura and Sonoma, do you have usb and hard disk available for testing? let's start from one of your hardware without mixing, we use opencore not clover so download a newer system than toi, i would start with BigSur or Monterey

che tipo di wifi hai?

anche a te Amico mio e a tutto il Forum.😀

benvenuto 😃,qui solo per la presentazione che os stai istallando? che spostiamo

e comunque aggiorna i kext sempre con OKAT e il driver HFSplus non è aggiornato

dalla foto non riesco a vedere comunque tieni il tuo config e prova questoconfig.plist.zip

comunque hai provato tutte le porte usb?

config.plist.zip tieni il tuo e sostituisci

il bios è settato a modo che la vede,- Boot -> Secure Boot -> OS Type : Other OS e fast boot su disable vai in alto link utili impostazioni bios

🤣io ho messo un Zippo accendino, sicuramente quello profuma di menta ed la scheda e fresca😆

dai un occhio anche qui

strange to me it works on Sequoia, try this and try disabling the Gatekeeper open the terminal sudo spctl --master-disable and reboot

ci sono anche schede pcie to usb 3 e type-c ne ho viste a 20€ compatibili con macos

no niente pcie disabilita il kext della rete, ma hai delle usb3 sulla madre? metti mouse e tastiera li e riprova

@Anto65 @fabiosun @tomnic ed altri mi serve una mano con safari fino una settimana fa' funzionava perfettamente, poi ho fatto un aggiornamento che mi ha proposto di safari, allora ho pensato ad un aggiornamento andato male ora continua a non caricare le pag., con Crome va tutto bene, a questo punto provando a resettare cache, preferenze e robe varie ma niente, ora ho aggiornato a Sequoia credendo che avrei risolto, macche...... niente non vuole saperne ora vi chiedo se ce magari qualche impostazione su Opencore che io ho erroneamente disabilitato che potrebbe creare questo?

@PPCnostalgic questa e la Efi quando vuoi provaEFI.zip, ovvio togliere i kext che a te non servono tipo rete, wifi e altro magari cambia n di serie poi a te non serve neanche usare le patch nvidia se hai la rx570 non dimenticare che da ventura è stato tolto il supporto a tante usb quindi devi usare tastiera e mause su le porte usb3, oppure usare un hUB

ormai siamo partiti 😀 Sequoia

che cpu hai? se vecchio cpu non funge puoi optare x i fakeSMC e HWmonitor cartella senza nome.zip metti questi pero disabilita VirtualSMC, scarica HWMonitorSMC e avvialo https://github.com/CloverHackyColor/HWMonitorSMC2/releases
