Here at XDA, we are always pleased to bring you news of a new multi purpose utility or automated way of rooting your device via your computer. The majority of these though are for PCs running either Windows or a Linux based OS. Very seldom do we see a tool for Android devices specifically developed for Mac users but we have one for you today.
XDA Senior Member northmendo has developed a tool named BreakDroid which will not only take advantage of previously established exploits and automatically root your device, it also has the ability to install the Android SDK and set up ADB for you. The developer states that it is still very much a work in progress with only four devices currently supported, however he intends to develop it to cater for as many devices as possible.
Currently Supported Devices:
Motorola Droid Razr (Should also work on other [ed: Motorola] Droid branded devices)
Galaxy Nexus (Testers needed)
Galaxy Note (Testers needed)
In order to enable BreakDroid to support as many devices as possible the developer needs people willing to test it out, so if you are a Mac user and would like to see your device supported by this tool or want to test it out or an already supported device then please check out the release thread for more information.
