Doesn't work on 10.12.3 (16D32)

When I try to type with sudo, the program doesn't even start working, just goes back to main screen. Also MANY ERRORS:

1. [Info] Enabling IP Forwarding...
   sysctl: unknown oid 'net.inet.ip.fw.enable'

   The system doesn't even know the command

2. 
   Traceback (most recent call last):

I don't even understand any of this.

The Problem is that you need IP/Port Forwarding on your Mac. On OS previous to El Capitan Apple used the 'net.inet.ip.fw.enable' kernel variable. This doesn't exist anymore so the script tries to change the value with "sudo sysctl -w net.inet.ip.fw.enable=1" but can't.

So please someone update this to Sierra!!

Meh, I already removed this and python stuff. There is no way for IP forwarding in Sierra so...rip the project.

when i input "sudo python arpy.py -t 192.168.2.100 -g 255.255.255.0 -i en0 --sniff", then it shows sysctl: unknown oid 'net.inet.ip.fw.enable' why?

On the latest versions of Mac you can enable port forwarding with net.inet.ip.forwarding

I have it setup in my fork of this branch.
