Mac doesn't recognize Android 2.1 phone

view full story

http://stackoverflow.com – I'm trying to set up my old Android phone for testing my apps. The phone is still on 2.1 (Samsung Captivate) and is inactive. I can't get my Macbook Pro on OS X (10.8.2) to recognize the phone. I have the box checked for USB debugging in settings, but when I plug the USB cable in, nothing happens. If I go to the adb directory and type ./adb devices, I show no devices attached. Any ideas? (HowTos)
