El Gallo Posted February 6, 2021 Share Posted February 6, 2021 Hi, I,'ve been trying to install catalina on my pc(msi mpg gamig plus z490, cpu i7 10700k) an I can enter the installation menu with open core but I can' t get the lan running. As soon as the apple sign comes the ethernet light turns of. I just have a windows pc. I tried all the kexts I could find for this lan but none worked... what am I doing wrong?

Slice Posted February 6, 2021 Share Posted February 6, 2021 Show please exact name of your LAN card and its DeviceID. You can look into Windows Device Manager and look Compatible IDs. You can also take Clover and upload here preboot.log obtained by F2. Quote Link to comment Share on other sites More sharing options...

El Gallo Posted February 6, 2021 Author Share Posted February 6, 2021 Hi thanks for the help but I can´t even enter the system because it is not installed. And I can´t install it because you need a internet connection to install and therefore I need my Lan working. So no chance. I just got another PC here where I have only windows installed. The one I wanna make a hakintosh is nothing on. It is a newly build pc. Quote Link to comment Share on other sites More sharing options...
iCanaro Posted February 6, 2021 Share Posted February 6, 2021 uses a virtual machine and downloads full macOS installer and not recovery alone Quote Link to comment Share on other sites More sharing options...
El Gallo Posted February 6, 2021 Author Share Posted February 6, 2021 (edited) The problem I have with a full installer that my opencore says at the beginning that this plattform is not supportet with this mac osx version. Why is that? I used the iMac 20,1 and the iMac 20,2 to generate smbios...none of them works Edited February 6, 2021 by El Gallo Quote Link to comment Share on other sites More sharing options...
iCanaro Posted February 6, 2021 Share Posted February 6, 2021 change: iMac19,2 Quote Link to comment Share on other sites More sharing options...
El Gallo Posted February 6, 2021 Author Share Posted February 6, 2021 Isn´t it possible to change the mac simbios somehow to make it load the installer? Quote Link to comment Share on other sites More sharing options...
etorix Posted February 6, 2021 Share Posted February 6, 2021 (edited) That's already a progress! The NIC may be initialised anew later in the boot process, so for now we need to find out which of the many possible causes of the dreaded halt at EXITBS:START applies. Do you have an OpenCore log? If not, switch to the Debug version. To change the SMBIOS, edit the config.plist, with matching MLB/Serial/UUID (which you should not leave in attachements).

It stops with the following screen... https://dortania.github.io/Getting-Started-With-ACPI/ssdt-methods/ssdt-prebuilt.html#desktop-comet-lake here more than a problem of rtl8125 we're still in the early stage pre-launch Quote Link to comment Share on other sites More sharing options...
El Gallo Posted February 6, 2021 Author Share Posted February 6, 2021 what do you mean? is something wrong with the ssdt as well? Quote Link to comment Share on other sites More sharing options...
etorix Posted February 6, 2021 Share Posted February 6, 2021 Yes, but it's not obvious what the issue is, besides the boot-arg, which should read "-v debug=0x100 keepsyms=1" (in any order, and optionally with alcid=1). At this stage, OpenCore has handed over to OS X but the Darwin kernel is barely begnning to initialise. Have you tried different settings? Do you have the OpenCore log for this boot attempt?

El Gallo Posted February 6, 2021 Author Share Posted February 6, 2021 No I don´t have it. I formated the stick again now. What settings should I try? I tried different versions of the iMac in the mbios. I can boot again and see if I can find the log file Quote Link to comment Share on other sites More sharing options...
El Gallo Posted February 6, 2021 Author Share Posted February 6, 2021 (edited) this is how far I came this time Edited February 14, 2021 by El Gallo Quote Link to comment Share on other sites More sharing options...
El Gallo Posted February 6, 2021 Author Share Posted February 6, 2021 Hi, I´ve found a solution for my problem!! In the install menu I had to go to the terminal tool and type in: ifconfig en0 media 1000baseT mediaopt full-duplex then the lan connection startet to work Quote Link to comment Share on other sites More sharing options...
