I have seen many questions regarding the set up of ADB under Mac OSX, and when I got myself a MBP I had the same question. After some research, I was able to find that is not as complicated as I thought it would be; it’s actually less of a hassle than setting it up under Windows or Linux. In OSX, ADB just works, as simple as that.
What is ADB?
ADB (Android Debug Bridge) is a handy tool that comes with Android SDK that allows you to control and interface with your Android device.
IMPORTANT Update 12/11/10 – There has been a change to the new Android SDK. ADB Tool has been moved to /android-sdk-mac_86/plataform-tools, so if you have the old SDK, please download the new one and update your path (Step 4.5 of this tutorial). If this is your first time doing this, then disregard the update and continue with the tutorial.
