Okay - I stickied the other thread, so please refer to it if you have questions about the procedure. In regards to Mac OSx, the same procedure applies. To run the ADB commands mentioned in the procedure, you need to download the Android SDK from
here. Once you've installed the SDK, you open Terminal on your mac, change directories to the tools folder for the Android SDK (for example mine is in Macintosh HD/Users/cstreater/adnroid-sdk-mac_86/tools), and then follow the procedure as written. Anywhere that the procedure says to type ADB something, you should enter ./adb instead.
