Macs with BCM57765 Ethernet Controller: System unresponsive with network cable plugged in

^{Originally posted by **patmaddox** December 23, 2021}
I'm trying to get started with 0.7 on a 2013 iMac. Something seems to not like my NIC (which uses `bge` driver according to `ifconfig`).

## Can't interact with UI when booting with network cable plugged in (doesn't finish booting?)

If I boot from USB with the network cable plugged in, it seems to not finish booting. I see the desktop, and an icon called `Starvolume`, but I don't see `Live` or `EFI` (which is what I see when I boot without a cable. The mouse and keyboard are non-responsive.

## Attaching network cable after booting makes UI non-interactive

If I boot from USB without the cable plugged in, I get a responsive UI and can open applications. I've opened the Terminal and looked at `ifconfig`. After I plug the network cable in, I can still use the Terminal and see that the NIC has been configured via DHCP.

Next I try to launch an application - `Create Live Media` so I can install helloSystem onto the internal hard drive. At this point I'm unable to interact with the UI at all. I can move the mouse cursor around, but not click anything, and the keyboard is unresponsive. I can no longer interact with Terminal either.

I don't have a clue how to debug this since I can't interact with anything after plugging in the network cable. Any ideas?
