Thanks for the reply ard. Know of any good ones that interprets bmw codes? Bavarian Autoparts has one made by Launch, but it's around $180. Just wondering if there's one around the $100 mark that works well with our cars.

edit: I also see that it looks like the Burger cable is the best for seeing all codes, including hidden. I am down for spending the extra money on the best, just wondering if it would work on a Mac since all of my laptops are Macs.
