[FEATURE] AppleEthernetRL Block (like Block SkyWalk feature)?

[fabiosun]

Your Improvement Suggestion
With a new shining kext derivated from Mieze lucy kext and adapted from Laobamac to work with New 8126A realtek ethernet chip, we have ethernet working adding a block as shown in this pictures using Opencore:

this is mandatory if Hackintosh users need to use OpenCore Legagy Patcher to have some wifi /bt features work

Motivation
This improvment allows user to use realTek ethernets 5GbE and lower in their hack

Implementation
Do you have any ideas on how to implement it? Feel free to suggest them.
No but the problem happens if you use an old IOSkywalkFamily mandatory to have WIFI working after OCLP patches

Additional Information
@jief666 could you check if it is possible to implement in Clover bootloader as you did for IOSkywalk block?

Tahnk you

I have an idea:

[Idea] Automatic blocking of AppleEthernetRL for macOS 26+ (Tahoe)

With the arrival of Realtek RTL8126A (5GbE) controllers, hackintosh users often rely on derivatives of Mieze’s LucyRTL8125 kext. On macOS 26+ (Tahoe), the native AppleEthernetRL.kext conflicts with these drivers — especially when OpenCore Legacy Patcher (OCLP) root patches are applied for Wi-Fi/Bluetooth due to the IOSkywalkFamily downgrade. This conflict can cause kernel panics or boot loops. Similar to the existing BlockSkywalk logic, making this behavior automatic on macOS 26+ would ensure a smoother user experience and prevent system instability.

Conceptual Implementation / Proposal: Add a new quirk BlockAppleEthernetRL. When enabled and OSVersion >= 260 (macOS 26+), dynamically inject com.apple.driver.AppleEthernetRL into gSettings.KextsToBlock, mirroring the existing BlockSkywalk logic to prevent conflicts.

if (gSettings.BlockAppleEthernetRL) {
    if (OSVersion >= 260) {
        gSettings.KextsToBlock.AddCustom(XStringW(L"com.apple.driver.AppleEthernetRL"));
        DBG("Forcing block of AppleEthernetRL (Tahoe+)");
    }
}

In KernelAndKextPatcher.cpp:

for (size_t i = 0; i < gSettings.KextsToBlock.size(); ++i) {
    if (AsciiStrStr(KextPlist, gSettings.KextsToBlock[i].c_str())) {
        DBG("Blocking kext: %s", gSettings.KextsToBlock[i].c_str());
        PatchKextName(KextPlist, gSettings.KextsToBlock[i].c_str(), "com.apple.driver.BlockedByClover");
    }
}

Notes: This is a conceptual implementation / WIP. Additional files and patches may need to be updated before full integration. Testing on macOS 26+ (Tahoe) is required before final implementation.
