Settings - OS X
How to configure your computer running OS X for direct Ethernet communication.
- Open System Preferences (available from the Apple dropdown menu in the upper left ).
- Select Network.
- From the Location: dropdown menu, select New Location... and type something like Make Controller. Any name you like will do just fine.
- From the Show: dropdown menu, select Built-in Ethernet.
- From the Configure IPv4: dropdown menu, select Manually.
Now we can enter in the IP address and the router/gateway for the computer.
OS X network settings for communicating directly with the Make Controller.
In the event that you don't need to preserve a wireless connection, the above settings will be fine - the IP address can be any that looks like 192.168.0.xxx. The value 210 in the above example is arbitrary, but make sure that you use a number that's not assigned to any other devices on your network. Note that this must be different from the address that you give your Make Controller.
If you need to preserve your wireless internet connection, choose another subnet that's not in use on your local network - 192.168.5.xxx is a reasonable bet, although again the 5 is arbitrary. You'll also need to change the Router setting to 192.168.5.1, or the equivalent for the subnet you've chosen.
To maintain your wireless connection, it's also important to set Airport as your primary internet connection, not Built-in Ethernet. To do this, click on the Show: dropdown menu, and select Network Port Configurations. Then, drag Airport up to the top.
You'll also need to change the network settings on the Controller in this case, which is outlined in the next section.
