macOS 27: ifconfig command no longer prints hardware MAC address

Just a quick PSA. A handful of my scripts broke today after installing macOS 27. Turns out they decided to redact the interface hardware ether/MAC addresses, all of them report 02:00:00:00:00:00 (…unless you run with "sudo") Luckily, you can still get the MAC addresses with networksetup -getmacaddress en0

I filed a bashbug: https://savannah.gnu.org/bugs/index.php?68722

Who needs a physical MAC address when you can just have a spiritual connection to the iCloud?

27.0.1 did not fix it, and I reproduced it on 2 more Macs, one was literally factory reset, just installed a fresh macOS 27, installed Homebrew, installed Bash5, ran ifconfig .... bug reproduced

Interestingly, running `ifconfig` from a Zsh shell still does show MAC addresses
