I’ve really been struggling to put an EFI together for my setup and I’m really not sure what I am missing I make it to the white Apple logo and load bar but it stalls half way through … help me please community. 
 

I have read that with the Kepler card I should be good to install  Catalina,Big Sur, Monterey… 

So here is the lovely screen that I feel like I have been waiting an eternity to see …. But now I’m here and it’s the biggest tease ever now I have no keyboard or mouse function … no USB port function … any idea how to fix this .. BIG SUR

 Sorry I thought I had posted it earlier. I couldn't get it to fix in the 10mb it says its 13mb so I sent via we transfer and I appreciate all help . As I was saying it took me  pulling an all-nighter to get to this point. It loads  up to the country select box and then my RGB keyboard goes out and I have no mouse control either. I have tried multiple keyboards moving the plug from port to port to see if i could just get one to work and nothing.

Hi, in the meantime I would update OC you can do it easily using OCAT https://github.com/5T33Z0/OC-Little-Translated/blob/main/D_Updating_OpenCore/README.md

 

You have the usbinjectall kext in OC / KEXT but it is not declared in the plist

 

You can delete the kext usbmap.kext .. unless you have mapped the usb (you must always declare it in the plist)

 

In device properties these keys must be deleted

The graphic properties are to be inserted in PciRoot (0x0) / Pci (0x2,0x0)

 

This is what I noticed at first glance, but also awaits the response of our gurus 🙂

 

 

You can use the tool I mentioned above, to update the ver. of OC, Kexts and edit the plist (you can use it from both Win and Osx)

 

With Propertree (check that it is up to date) Just do "OC Snapshot" pointing to the OC folder
I would exclude the kext for Bluetooth at the moment

@ esaf can i get you to take a look at this EFI for me .... I did the usb map tool and added a UTB.kext from my motherboard's usb profile but i know i did something wrong or didnt finish a step because i didnt understand the guide for it much beyond generating the files and putting them in the correct folder can you double check that for me please . im not getting any errors in OCAT when i scan it but when i try and boot it .... the applo logo comes up my keyboard stays lit but the progress bar never starts.

Are you sure there is USB problem? May be the computer fully stall?

@slice soon as I booted back into OCAT on windows and removed the UtB kext and usb tool kext it went back to booting just no keyboard or mouse once I get to the install screen …. I thought I did it right but I didn’t see a path once I loaded the kext in ocat … any help would be appreciated

Sorry, once again. Your computer booted up to the install screen and then hangs. Yes? 

Correct,,, but in the last EFI I posted I’m not sure the utb and usbtoolbox kext are set up correctly to properly initialize during boot… I posted it to see if someone can double check it for me to see if I did it right or wrong
