How to remap a network interface in OS X?
On a MacBook Air with Wi-Fi, the BSD Name is always en0. Thunderbolt-to-Ethernet has always been en3. After Wi-Fi broke down, the en0 interface disappeared, at the same time Apple services (App Store, iMessage, etc.) stopped working, as it turned out, for some reason they require it to be active. While I'm waiting with aliexpress for a new wifi, I would like to use these services.
Removed all network services from System Preferences. Removed network settings files:
sudo rm /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
sudo rm /Library/Preferences/SystemConfiguration/preferences.plist
sudo rm /Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
sudo shutdown -r now
