The kext is working in my build with bcm5701 ethernet card and high Sierra. Sometimes after restart the network card disappear. The most strange thing is Mac address is not the original Mac address from the network card but the 00:01:02:03:04:05. Can someone have a idea how to solve this issue ?
My Ethernet device now shows up but it always says unplugged. If I boot into Windows, it works fine. I checked and it is en0 for BSD name.
I went to Network prefpane, and removed it from the left column and applied then rebooted and deleted /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist (and also preferences.plist). Rebooted. Still shows unplugged.
Dell Vostro 230
GMA X 4500 Chipset with some type of BCM BCM57788 Ethernet port.
Nvidia GTX 970
Sierra 10.12.6 Build 16G29
Curios whether anyone has been able to get BCM Ethernet working on High Sierra. I tried 12-15 kexts without success. If someone has found a solution, please share. The mac i am working with is an i7-2600k, asrock z68 extreme4 mobo, with a nvidia gtx 650ti. Thanks to all.
I have found a solution for Broadcom 57781 in ASRock z68 extreme4 gen3!! Works for me perfectly, even after OS updates
1. You need to delete (create a backup on Desktop before) High Sierra's IONetworkingFamily.kext in HD/System/Library/Extensions
2. Download my Zip Archive in attachments
3. Open Kext Utility or Kext Drop and install all 3 kexts from my zip archive in this order one by one
Should work fine!
PS I just took IONetworkingFamily.kext from previous versions of macOS where FakePCIID by RehabMan worked perfectly. So, it has worked in High Sierra too!
