How to Set Up Apple TV 3/Apple TV2 as a Ditto Receiver
Step 1 - Gather Apple TV network Information
If you choose to manually add an Apple TV through your Ditto account portal, you will need the IP address and the MAC address. This information can be found on the Apple TV "About" screen.
The IP address and MAC address will be listed on this screen.
Note:
Apple TV refers to the MAC address as "Wi-Fi Address" or "Ethernet Address."
Pro-Tip: We recommend setting a static IP address for your device to prevent unwanted IP address changes.
