I found a guide on how to install Catalina on Lenovo M920q, everything works well but the installation is freezing up.
The USB bootable drive is a recovery one with internet based installation. The internet is working well on the pre-installation setup (I tested it, when you can use the utilities).
The installation is freezing whether I am installing the macOS or not.
I've attached my EFI partition so you can check if there's anything to add.
Will realy appreciate any kind of help (quit noob to the whole thing).
Thanks in advance and stay safe!
NOTE: I did followed up the troubleshooting guide of OpenCore installation forum and the answer was to add the NullCPUPowerManagement.kext to the kexts and configure it on the .plist file.
This is the original EFI folder: EFI.zip
Thats the one with the NullCPUPowerManagement.kext added: EFI.zip
spero tu mi possa aiutare ,perche' non riesco piu' a far partire i miei 2 ssd 850 samsung sui quali highsierra funzionava perfettamente da 1 anno e non ce' maniera di farlo ripartire .unica cosa e' che riesco ad arrivare alla console dell'istaller e ho tentato varie volte di ripristinare da una time machine che ho salvato su un altro disco usb .
il mio sistema e' un asus p5qd turbo ed e7500 dual core . grafica gtx1050 chr funzionava con accelerazione e webdriver nvidia .audio voodoo 282. e boot clover che e' sempre stato il 5103 che poi ho aggiornato a 5120 proprio il giorno prima che succedesse il fattaccio .quel giorno ho aggiornato dal sito apple la comboupdate 10.13 .6 da 10.13.4 .e qui al riavvio boom niente diski in clover nn li visualizzava piu .ora sciacciando f3 visualizzo il preboot e lssd con highsierra aggiornato ma arrivato alla console andava in reset loop .
a questo punto riesco a ripartire togliendo l'accelerazione .e installando i nuovi webdriver di nvidia aggiornati all 10.13.6 .
al riavvio non parte piu' con accelerazione e sempre problema in clover dei diski ma riuscivo a partire con f3 e preboot .
ora decido di installare da time machine e tornare alla versione 10.13.4 del giorno prima ..e al riavvio niente piu dischi ne preboot .sono fermo a questo punto ..riesco solo a far partire installer ma nn so i comandi da dare in terminal per aggiustare le cose . ho anche linux su un altro notebook. ti ringrazio anticipatamente per l'aiuto .

If no mouse, install all voodoo kexts using Kext Utility
This esentially an ultra-simplistic version that is stable without the use of a deploy or complicated file installations and copies.
You can easily view all the SSDT patches along with configuration files for the bootloader as they are all documented clearly in the files.
This does include a copy of Clover, which of course I do not contribute to and am only responsible for the provided files, patches, and kext placements
This guide provides a working setup with little knowledge of the topic and without "optimization" (because often they can break things). But, it is fully functional and preforms properly and is stable
Make sure you are using DW1560 for wifi or else KP. If not using remove BRCM kexts from CLOVER>kexts>other.
Disable Secure Boot
INSTALL (VERY IMPORTANT)
Due to structural changes in the setup of apple's Big sur, this EFI cannot boot the installer it can only boot into a system / device that has already been created and setup.
To do this, you need to install Big Sur to a virtual machine (lots of guides online) and then create an dmg of that system, and restore it onto your HDD using the 'dd' command
There are various guides online how to get this virtual machine setup complete.
You can then use the attached EFI folder to boot and use macOS big Sur
You can use this video to show you how to get your macOS pre-installed onto your hard drive https://www.youtube.com/watch?v=HMU3nhcbWHw
Boot Entry Setup
Due to the fact this BIOS is locked down pretty heavily, reccomended to use Windows to find a free tool to add UEFI boot entries
Messages and Facetime
Gnerate your own Serials, Board Numbers, MLB
There are various guides online to do this and as default they're set to essentially Null (Fakeserial)
This is fairly straightforward and there is lots of external recourses, or you can contact me for support.
Headphones and Audio
All audio from speakers should work perfectly along with Bluetooth and USB audio
no internal mic

So, here's what i think clover do when it patch ati framebuffer, first it read a cached kext, then it search the original hex value of the connector, then it changed the value with the new one. Is it correct? now, here's what i find confusing... let's say that i want to patch AMD7000Controller.kext, in that kext, i want to patch "AJI" framebuffer with a new value, so clover try to find the hex value of "AJI" connector then replace it with the new one, simple right? but when i search the AMD7000Controller binary file for other framebuffer, some of them didn't exist in the binary, for example, i tried to patch "Ramen" framebuffer, from various source, it said that:
Ramen (6) @ 0xeba70
LVDS, HDMI, DP, DP, DP, DP
So i open a hex editor and search for:
but, it turns out that hex editor couldnt find that hex value in AMD7000Controller,
most of the framebuffer exist in the AMD7000Controller, but some doesnt, If this is the case, then, where does clover find the original framebuffer to be patched? am i missing something?
