The software provided with the LEGO Mindstorms NXT for Macintosh computers was compiled to run natively on machines with PPC processors. For Macs with Intel processors, PPC-native applications run under emulation mode using Rosetta.  Unfortunately, the Rosetta emulator does not support bluetooth at this time, so NXT users are anxiously awaiting a universal binary with the hopes that it will bring improved NXT-G IDE performance and bluetooth connectivity.

With yesterday’s release of the NXT development kits, however, Tony Buser did some research and was able to successfully establish a bluetooth connection between his NXT and Macbook!  Small steps towards his eventual goal of creating a Ruby module capable of communicating with his NXT via bluetooth.
