Error booting Sonoma install - Dell Optiplex 5055 Ryzen 2400G

[IdidIt]

Hello,

Well I hope I can get some help from some Mac Guru

The PC is SFF Dell Optiplex 5055 only the SSD (noname) is not from the original computer
In bios AMD-V is enable, Secureboot is Disable
I followed this guide on youtube to create a EFI.
I downloaded Sonoma Basesystem with this code

python3 macrecovery.py -b Mac-937A206F2EE63C01 -m 00000000000000000 download

I used the dell specific option mentionned in the guide and the config.plist was validated by the application.
The only thing I was not sure is the Kext for Network, since the ethernet is BCM5762B0KMLG I used BCM5722D.kext

Note1: I also tested with the SecureBootMod on disabled on the config.plist
Note2: UpdateSMBIOSmo is set to Custom because otherwise OCAT gives an error since I am using Dell

here is the error I get after I choose DMG to boot:

I replaced Sonoma with Ventura and I had same error BUT after it booted to MacOS install.

New problem is "No Network Connection"

Must be the ethernet Kext.

This PC is using BCM5762B0KMLG if I refer to the website.

And only Kext I found was BCM5722D.kext

I found this https://github.com/unitedastronomer/AppleBCM57XXEthernet

Ethernet (Internet) is working I can ping local ip and Internet ip.

But the latency is too high I have 1000MS when I ping an internet IP on this computer.

I can't install macOS ventura I got an error "The recovery server could not be contacted"

Try NVRAM reset and then check. If the error persists, change the DNS.
