This worked for me and I verified functionality by tuning in a local FM station with gnuradio You need installed MacPorts on your system: https://www.macports.org/install.php install GNURadio:

$ sudo port install gnuradio

Go get a coffee, work a day, have a beer, check on it. This will currently give you an install of gnuradio 3.3.0 – which does work even though the docs indicate it won’t. install libusb driver:

$ sudo port install libusb

install rtl-sdr:

$ git clone git://git.osmocom.org/rtl-sdr.git
$ cd rtl-sdr 
$ mkdir build 
$ cd build 
$ cmake ../ 
$ make 
$ sudo make install

test it:

$ rtl_test -t
