ADB Doesn't recognize Nexus S in Mac 10.6

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开发者_开发技巧 charm.

Any suggestions on how to make the nexus s be recognized to the ADB of my Mac?

Thx in advance!

As far as I know, the "Usb Driver Package" is for Windows only.

Did you tried to download and use the newest SDK/ADB from http://developer.android.com ?

I had some problems too these days, but after rebooting my phone and reenabling the debug mode ADB worked again.
