I'm new to the Pineapple but I love it so far. Just thought I'd share a process to get Internet Connection Sharing working in MAC OSX without having to make manual edits to the Pineapple as the Wiki states. This requires the Network Manager infusion be installed. Step 1: Connect MAC wifi to your Internet connected AP Step 2: Ensure to "Set Service Order" under the Network preferences, put the Wifi above the Ethernet Step 3: Also in Network prefs set the IP address of the Ethernet connection
