I've been having issues getting UFiber.Configurator to write the MAC address.

➜  macos-x64 ./UFiber.Configurator --host 192.168.1.1 --vendor ARLT --serial ######## --mac 30:B1:xx:xx:xx:xx

When I use it just to write the serial, theres no problem.

I was finally able to get the MAC changed as a third step using usb_serial_hack.py

I hope I am not saying something wrong, but I just went through the same process and removing the colons from the MAC address solved the issue for me.

Instead of passing the mac as --mac 30:B1:xx:xx:xx:xx, try --mac 30B1xxxxxxxx

I hope this helps.
