Hello, I was wondering whether Canon's Bluetooth Unit (BU-20) is compatible with Mac OSX to print wirelessly. I have a Canon MP500 Multifunction Photo printer with Bluetooth Capability only if I purchase a BU-20 unit sold separately. So, I wanted to know whether its compatible before I purchase it at Amazon.com or any other online retail stores. Please let me know because I would to use my Canon MP500 that is currently connect with my PC. (I tried printing over my network via wireless, but whenever I start printing, it would say its complete--but really, the printer didn't print anything at all.) Thanks; Any help is appreciated.
