@Katanoko1221 Happy for you Backup this working EFI and re do one in more canonic way (to be fast i have bypassed completely MMIO whitelist) and you have also to check well all your bios settings, patches and kext used and so on By hte way single core cpu seems a bit low, you should have about...

@Shaneee i used config he posted above in full his efi I disabled only some stuff like visual patches that could create provlems for amd in installation step

Gaetano check this thread, you could find an EFI to start for your Gigabyte board could be necessary also to patch DSDT (if you see some ACPI error in verbose mode during the starting process)

try this config if the same problem try to change usb port (if you are installing from an USB stick) Check in your bios if you have 4G option and set to On CSM off in boot menu reset Nvram idk rnme ssdt function also build from windows or with mac/hackintosh your SSDT EC/CPU usbx to start if the...

@unclesam your platform is a bit different than @Katanoko1221 However you can use the one i posted for him and then post your sysreport folder and opencore log

It always did in that way also with other user with9900x

Opencore problem for you cpu is solved i think Now we have to refine better your efi Try to disable from your bios Wifi , ethernet and igpu

Post a video to see if in debug there is some acpi errors

if you have this one both ethernet and WIFI are unsupported for now so i think you would need (when system starts to boot) of an Ethernet USB adapter

Now worked

check easyupload link in these days attachement here doesnt work and i dont know why proble for instqallation is a second step to solve. Now is mandatory to see if opencore detect in a proper way your CPU after the great job done by Shaneee

https://easyupload.io/a0l70e ops sorry. i have problem to upload via attachement these days (i d k why

by the way, you are trying to install via recovery so you need a working ethernet /wifi connection to complete installation (when Shaneee will solve CPU family Opencore problem)

I dont know where your EFI come from you had all mmio whitelist area on but DevirtulizeMMIO quirk disabled..other stuff are weird but unrelated to your problem. if now you saw cpu correct in previous log try only to boot with this attached EFI I updated some kext and activated sys report to see...

Is it possible to see EFI folder @Katanoko1221 is using by now?

you could ask where you took that EFI :P apart joking my EFI is calibrated for my "old" system SSDT Bridge is not useful and also double 6950xt Device Poperties are not usuful Kext block and also some kexts are usuful if you use a broadcom WIFi togheter OCLP app I do not remember if kernel...

Wifi 7 never will be working (i think) Ethernet: Aquantia 10Gbit works with quirk and patches Intel 2.5 Gbit (i226) works with kext realtek 2.5 gbit "should" work with kext realtek 5 Gbit it seems doesnt work for all

@Katanoko1221 If my config plist gives the same hang you had before doing a mmio whitelist will not solve your problem because in that config i bypass mmio problem Sorry, problem could be in opencore which doesnt recognize well your cpu

i didnt know about additional tests done in another site :) but if @Katanoko1221 would try my config we can see if it will be the same problem

@Katanoko1221 log you did is not useful because it misses some data like MMIO part In the past we did some tries with an user with your same CPU and we failed (i do not know if @Shaneee solved this very weird beahviour or if it was a "user" problem Meanwhile, i suggest to prepare a debug EFI to...
