Sto tentando per milionesima volta ? di installare big Sur su hp Spectre ma si blocca dopo pochi secondi e ritorna alla schermata di opencore io o seguito la guida di dortania ma non riesco qualcuno ppotrebbe darmi una mano metto il config e il txt di opencore opencore-2025-11-19-150231.txt.zip Config.plist.zip

probably we should find pci address for rx slot and build a bridge for it with ssdtime if you do not do damage i would for only try to remove your 4090 and use rx 6600 on first gpu slot near CPU or try to enable whatevergreen kext if disabled or enabled it... now all is good and the only variable are your beast unsupported installed on system (i dont know how to disable it correctly in OSX) other variable is PCI bridge for your slot

So it’s now showing but only on 4090 the 6600 remains no signal I’ve gone though account creation and now stuck on a gray screen

you should not see verbose output do for a couple of time

So using the above file the bar gets around 1/3 of the way and then the computer restarts

try config plist put above

It’s seems to vary where it stops I’m reinstalling just in case something went wrong and then if not I will try the above file and report back thank you edit: now gets stuck here constantly

did you wait a bit and always stuck there? if so you can try to disable -v in your boot arg and see if it works config.plist.zip

So it seems to be stuck at AppleKeyStore:pid94,:13108 operation failed (sel: 7 ret: e00002f0, -1) it installed find this was after it rebooted rebooted again and now stuck at

let see if it instal then we have to see if your gpu is accelerated and audio part 🙂 happy for you also for me because i thought i lost my touch (in hackintosh ) 🙂

So using the 10g now and it’s working installing now

config.plist.zip using aquantia Archive.zip using intel ones copy the kext in your /oc/kext folder try both separately (both config posted)

If you don't mind, that would be greatly appreciated

you should try with both lan you have but we have to modify your config if you like to try i will do for you let me know

So I run the 10G LAN (Marvell) as i have 5gb fibre Honestly thank you so much for all your help

ohhhhh ok we can try to enable your aquantia or the other one

Its working!!!! Can boot all the way into recovery but then complains there is no internet connection but i can at least get there now thank you so much

config 2.plist.zip press space bar reset nvram then try again

We have progress! It hangs here, but we are moving forward Thank you for all help so far

could you connect both monitor on rx 6600 (leaving your 4090 inside)? and press space before launching your USB pen icon (then reset Nvram)

so still a black screen on both gpus

overwriteconfig.plist only with this config.plist config.plist.zip

post a video if you can from when you start the system and choose your usb sticks

this is not relevant (sorry) because i think it happens before you see the boot menu Or after? i mean apfs efi on rx amd gpu @khiletry this EFI and post a video disable on bios asus logo and fat boot please EFI 2.zip
