The keyword for making this hardware useful is Software Defined Radio or short SDR. And since the hardware is based on the Realtek Chip RTL2832U the software supporting it is called RTL-SDR.
I kind of expected an annoying process of getting it to run on Mac OS X Yosemite (10.10) but it turns out it was very easy. Just follow these steps.

2. Install the Software
After the installation has finished, plug in the tuner and test it by executing:
Giving me this this output:

which looks good!
3. Run GQRX
Now that you hopefully have a running gqrx. Execute it from the command line:

A ridiculous amount of coffee was consumed in the process of building this project. Add some fuel if you'd like to keep me going!
