Internet problems on dual Socket Hackintosh

Good afternoon,

Recently, I built a Hackintosh on a Supermicro X10DRI with 2x Xeon E5-2603 v4 CPUs. Now, I'm having some problems regarding networking. The Hackintosh is running macOS Sonoma and has 2 onboard Intel I350 NICs and a dual-port 10 gig X550 PCI card. The problem is that the 2 onboard NICs are showing up as modem/serial ports, as shown in the picture. Unfortunately, that’s not the main problem. The main problem is that the dual 10 gig card shows up in System Information and in settings; it also shows both ports correctly. But as soon as a network cable is plugged in, the settings say 'self-assigned IP' or it crashes with the error report in the picture. Also, the system bootloops with a network cable connected. I have tried different things such as other drivers, but nothing seems to work. To my surprise, with a simple USB to LAN adapter, it’s working flawlessly. In the pictures, I also provided a screenshot of my Kext files. I would appreciate help and will thank everyone in advance. Also, if someone has questions regarding the server hardware, feel free to ask.

My Bad I forgot the pictures

Ensure that your serial ports are disabled in the BIOS settings.

You don't need agdpmod=pikera with a WX4100.

Suggest changing SMBIOS to MacPro7,1.

Google 'kext for Intel I350' to see the litany of problems with these network interfaces.



You don't have Intel I225-V Ethernet controllers so adding the boot arguments for them is not likely to have a beneficial effect.

also you should remove the other ethernet kexts you are not using

Thanks for the fast reply. Unfortunately I’m not home for the next 3 days. But I will try all things you said and will reply to this thread

Hello again,

unfortunately if I change the boot arguments the system refuse to boot as shown in the picture. Maybe anyone has some tips about this issue.
Perhaps another solution would be for me to purchase a dual-port PCIe card that should work seamlessly without additional configuration. I would appreciate recommendations for a half-height card or tips for the problem.
Thanks in advance

set Vault to Optional in your config.plist

For your Intel i350 NICs to be recognised and work in macOS you might need to add SmallTreeIntel82576.kext to your /EFI/OC/Kexts folder and config.plist.


Alternatively, you can try adding the DeviceProperties patch to your config, you would need to do this twice, using the two different IOReg Names, one for each NIC.


Have a read of this post regarding the Intel dual port X550 NIC.

I tried with the SmallTreeIntel82576 but unfortunately I didn’t help. I will now try the device property patches.

Unfortunately I didn’t work. So I was wondering would this card work out of the box without problems? https://www.amazon.de/Annadue-Gigab...tzt-default/dp/B0B77K9Z6Z?tag=tonymacx8603-21 Thanks in advance
