Thank you Uwe for your work. I tested it on 10.8 and it worked. I do get a system dialog box asking to Pair the wiimote with a passkey, but if I leave it blank and press buttons 1+2 it WW usually autopairs on the second try.
I do have a question about the TUIO messages. I see active is one message and then the message that looks like the screen coordinates. I see three (are these Width, Height, and Z(distance from screen). If this is documented somewhere please let me know, I couldn’t find it.
