BCM57785 Catalina

Recommended Posts

Has anyone got a Broadcom BCM57785 ethernet card working on Catalina?

Up until now I have been using an old IONetworking.kext which had a modified AppleBCM5701Ethernet.kext in its plugin folder.

Things got a little more complicated when Mojave came along. Support was dropped for my atheros wifi.

Although putting the old Atheros kext in L/E got it working, that would kill my Ethernet.

The answer was to use old versions of both IO80211 and IONetworking, then both worked happily.

I have tried the same in Catalina but with no success. I can get wifi by putting the Atheros plugin in L/E but cannot get Ethernet.

I'm not entirely convinced they are installing correctly, I have tried in R/W mode and chmod and chown and touched and rebuild caches with no luck.

Anyone else using the same Ethernet with Catalina?

I got my ethernet working using FakePCIID.kext and FakePCIID_BCM577XX_as_BCM57765.kext installed to /S/L/E

I then got my wifi working by installing my old IONetworking and IO80211 kexts to /L/E
