Add support for Broadcom Ethernet #65

Open unitedastronomer opened 3 days ago

unitedastronomer commented 3 days ago

I have written a mini-guide on how to fix ethernet support on certain Broadcom Ethernet on macOS Big Sur and newer (minKernel 20.x.x). Loading the native kext don't work anymore unlike in Catalina and older with FakePCIID.kext.

IOName instead of device-id spoof works too, it's helpful if the user really wants to show the real name of the card instead of the spoofed one.

The patches mentioned in the guide should still work to load the native kext on Catalina and older, but just change the the identifier from "CatalinaBCM5701" to "AppleBCM5701" (maxKernel 19.x.x) in Kernel > Patch

In NetXtreme/NetLink BCM57785 Family Programmer's Guide, there's the BCM57765 used in iMac11,x.

Others are not listed in .kext's info.plist should still support those cards as they are still from same family.

Supported device-id(s): This list is based on supported by FakePCIIID kext on Catalina.

Hi, I don't recommend getting the kext in AppleLife as the website will delete attachments as it gets older, grab the CatalinaBCM5701 in OCLP's repo instead.

Big Sur to Sequoia

Easiest:

Just grab the mirror of the AppleLife kext in this repo. that's all. no need spoofs etc.

The more technical one:

Device Properties: Key* Value Type
IOName pci14e4,16b4 String
compatible pci14e4,16b4 String

Use IOName instead of device-id,so it would show the correct model in Hackintool, spoofing one of the IOName match from it's plist just works fine.

3 5 3 7 3 7 3 6 3 5 -> 3 5 3 7 3 7 3 8 3 5

Catalina and older

Easiest:

Just add FakePCIID kext. that's all. 💯% working.

The technical one:

Device Properties: Same as above Patch: Just enable "BCM57785" patch in the sample.plist. Cosmetic: Same as above but the identifier is com.apple.iokit.AppleBCM5701Ethernet, maxKernel: 19.99.9

I cannot use the "BCM57785" patch present on sample.plist on injected kext (on macOS >=11) even with correct identifier because masking don't work there.
