Bizarre... I tested on my Macbook Air, and it worked with no problems. Now when I plug it back into my hackintosh, it works just fine! At any rate, thanks for writing this fantastic piece of software! I was about to toss this device as the software no longer works after Snow Leopard. Now it's as useful (if not more, with the quality of your software) as the day I bought it!
