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...

@tr4c3r2k12 if you can put your system in signature try this exactly config.plist and see if it boots (do not change anything) if it doesnt boot play only with MMIO part (disabling /enabling them in a single way, only one at tries) for display problem, better to disable internal GPU via bios...

Hi! Your EFI misses two important part to configure well AMD x870 chipset 1) SSDT-Plug in ACPI section 2) MMIO whitelist area properly done for your MSI motherboard *3) your MSI board like other manufacturer could have the need to patch some acpi you should use a debug version for opencore and...

I'm writing again in this thread after doing several "experiments" with my new system and especially after adding my second GPU I had to move my broadcom wifi internally that I was previously using on a PCIEx adapter mapped the usb and everything work(ed) perfectly..or so it seemed to me...

@JohnFante Proihibit sign could be related to usb problems. did you do what i suggest some message ago about MMIO? You enabled 4 MMIO areas, have you tried to leave enabled only one (the second one in your MMIO list)? Opencore is not a problem and you could update from a release version to a dev...

yes you have to change also opencore.efi from debug to a non debug version and remove also -v bootarg from your config.plist (nvram section)

Mylo, dont take this in a wrong way but this EFI is a mess :) :) you use many kext and block for the app OCLP and also many stuff for Intel wifi But, your SIP is set to 0000000 So, which hardware are you using by now? I know your X570 motherboard, i miss all other components to understand...

@JohnFante if you like to use innie kext as before and you had success with my last EFI, enable it again usually i disable all not mandatory stuff to resolve booting problem ;)

i use Device Properties to bypass orange icon for internal drive you could try the same you could also try with external icons quirk I prefer Device Properties and use less kext i can

I meant if it doesnt work from when you updated to a new bios Try to see if dsdt needs some patches for new bios

have you updated your motherboard Bios?

I suggest to try to leave only the second mmio enabled and see if it boots fast If you have all stuff i see in your signature maybe some devices slow your boot

@Mylo i see your EFI in other thread in Sonoma it was working if i understood well is it always working in Sonoma, or now you doesnt boot any osx? if so, Have you updated your Gigabyte Bios? i see also you use DevirtualizeMMIo quirk and disableVariableWrite quirk they shouldnt be useful for...

@JohnFante I used now your last working EFI backup This EFI couldnt work for latest OS for three main reasons New AMD kernel patches, new MMIO changed with latest bios you use and SecureBootModel setting Let see now i disabled some kexts for now till you will be able to pass that hang Edit I...
