I have given up...ok, the bit about creating building an Apex boot loader entry, when I type this in Terminal...
SUDO arp ñs <10.0.1.6> c:1d:12:e0:1f:10
I get no such file or directory.
TextEdit does not like that readme file..some chars are garbled, yet fine with cat The command switch is actually -s not ñs. And you don't actually use the brackets... they are there to indicate a value you must substitute in.
The full command should be:
SUDO arp -s 10.0.1.6 c:1d:12:e0:1f:10
(assuming your Apex's IP address is 10.0.1.6)
