Classification:Serious Bug Reproducible:Always
SetupAssistant appears to be hardcoded to en0 or only looks for the presence of Wi-Fi when attempting to install "Critical Updates" EFI Embedded OS on Touch Bar MacBook Pros.

This should be extended to allow Gigabit adapters or Thunderbolt monitors/external devices.

Reproduce steps
1. Boot into Internet Recovery with Touch Bar MacBook Pros utilizing Apple Thunderbolt 3 to 2 adapter -> Apple Thunderbolt 2 Gigabit Ethernet adapter
2. Open Disk Utility and wipe entire drive
3. Re-install macOS Sierra 10.12.1
4. Upon finished installation, Setup Assistant will ask you to install a Critical Update and connect to Wi-Fi.

Expected Results
Sierra should intelligently detect the presence of a network adapter, contact, download the preflight package and re-install/activate the TouchBar EFI partition.

Actual Results
Sierra SetupAssistant asks to install a Critical Update and connect to WiFi
