Hi, using Snow Leopard on a core 2 duo macbook and installed the latest dev system, which launches fine. I also installed the latest USB drivers, which seemed to install fine, but did not create the usbserial devices. So when I choose a serial port in the arduino app, all I get are the bluetooth ones.
I looked around the forums and used google, and though I saw lots of issues with OS X, I didn't see this one.
Any wisdom out there?
