I just bought the Nexus S with the android version 2.3.3, which I update it to 2.3.4. I use to develop my android apps in my Mac but when i tried to connect my new Nexus S with the ADB it wasn't recognized. Though the ADB worked pretty well with pass android devices.
Moreover, I connected my Nexus S with the ADB under my Linux machine and then worked as a charm.
Any suggestions on how to make the nexus s be recognized to the ADB of my Mac OS X?
