Native support for Intel I225-V on Sonoma

[atanvarno]

Current Sonoma versions (I have 14.3.1) should support Intel I225-V Ethernet NIC out of the box. I have that working with MacAbe's SSDT + AppleIntelI210Ethernet_i225v.kext + e1000=0 boot-arg but would love to remove all that and use native .dext. (I prefer as simple EFI as possible)

Thus I removed all of that + deleted two .plist files to force macOS to re-enumerate network interfaces on next cold-start.

On first glance, after restart, everything seems fine in SysInfo, Hackintool and IORegExp:



Interesting to note here is that device-id and other values are exactly the same as SSDT I was using previously.




But turning WiFi off and connecting a cable will get me only self-assigned IP and after some short period of time entire macOS would crash.
I was watching the Details panel in System Settings / Network and driver would correctly negotiate 1Gbps speed which is maximum for the router port.

Not sure what this could be.

Here's one crash log, not sure how useful it is

Remove the SSDT, kext and the e1000=0 boot argument, then enable VT-D in your BIOS and disable Kernel > Quirks > DisableIoMapper in config.plist.

See if the Ethernet port works with the native dext provided by Apple.

I've never been able to get native support working for the i225v controller on my AMD machine, I'm still using AppleIntelI210Ethernet_i225v.kext with the boot argument e1000=0. AppleIGB.kext does not work for me either, with or without a boot argument, I don't need any SSDT's though.

 

[atanvarno]

Mildly interesting: there's this oft-linked page explaining how to apply custom firmware to the I225.

It includes a screenshot showing what is changed in the firmware so macOS can recognize it. I assume the non-green area is identical to original firmware they modified.

I used the same eeupdate64e.efi to extract the firmware file from my board (Asus B550I) and when comparing that original and modded one, there's quite a lot of difference. Thus I assume my NIC has different firmware than Gigabyte's Z490 Vision G board where this was taken from.



Fun.

I doubt I need this at all since Sonoma 14.3.1 recognizes my particular one but it is interesting to note that a lot of different I225's exist out there.

I wrote in the first post I have removed SSDT, boot-arg and kext. Re-checked Device Properties to make sure nothing references Ethernet NIC.

Regarding BIOS, I tried with IOMMU on/off and/or SVM Mode (CPU virtualization) on/off. No difference in behavior.

 

[atanvarno]

For whatever reason, native .dext driver in macOS Sonoma (currently on 14.3.1) won't work with I225-V on Asus ROG Strix B550I Gaming. I tried pretty much anything and it simply does not work. I'll keep checking in future Sonoma updates as it is likely some bug in the native driver itself; maybe they fix accidentally.

Thus for now — using AppleIGC.kext (version 1.4d1) and added e1000=0 to boot-args to the disable native driver. This works very reliably, including Messages and FaceTime.

Note about BIOS 3402 settings: IOMMU is set to Enabled and SVM Mode is also set to Enabled. First one is equivalent to VT-d on Intel and it is likely crucial settings to enable AppleIGC.kext to work.
