recently the bluetooth compatibility on my mindstorms NXT 2.0 has stopped working, the mindstorms porgram now does not recognise it as a bluetooth device, it says "unavailable". I run mindstorms v2.0f5 on a 2009 macbook (wich I recieved in 2011) the computer runs on 10.8.3 mountain lion and the NXT runs on firmware 1.31. I have established that the bluetooth connection on both machines (laptop and NXT) as I can in fact pair the two devices. the problem is the NXT Retail program itself, it just does not connect making it useless, so there must be some patch to the program. I have attached a picture of the window in question, when I hit "scan" essentially nothing happens, it appears to be searching but within a millisecond the screen returns to its previous state (the state the picture shows). I watched it in activity monitor when I hit scan and the program did nothing, nothing new came up. Please respond with any ideas, questions or even possible fixes, I really need help here!
