When running scapy in interactive mode on MacOS 10.14.5 I get the warnings below.
scapy 2.4.3rc1 and python 3.7.3

If I try to do something simple such as sending an ICMP packet, scapy says WARNING: Could not get the source MAC: No MAC address found on en0 !

en0 does have an IP address

Similar result, but the warnings are a bit different.

Thanks. Is it the regular ifconfig command for 10.14? The output is different from previous version of the OS.

I just confirmed on two different installations that this it not the regular output of the ifconfig command on 10.14.

Ah, a light bulb just went off. A while back I was experimenting with installing GNU coreutils on my Mac. The man file for ifconfig on my Mac does say GNU inetutils 1.9.3-dirty, so that must be the reason for the discrepancy. Now I need to figure out how to restore the original ifconfig command. I'm assuming this will clear up the issue.

Hi, I've faced a similar issue, but, I already tried the:

@221910312031 you probably have ifconfig from GNU coreutils, see @mikeassel comment.
