RTL-SDR on Mac: the easy way


Julty 17th Update: permission granted! This version should work without any installation or any setup. Just extract the zip archive and double click on executable file. HDSDR OSX

The hobbyist who wants to try Software Defined Radio receivers will generally run into two problems: the price of the receiver and the fact that they will need Microsoft Windows.
The RTL2832U solved the first one allowing an incredible number of people having their first SDR experiences almost for  free. The second problem however is still out there: some of us can't really stand Microsoft Windows but even with the RTL they are somehow forced to rely on it. Yuck!

The best solution to this is using Wine. I don't mean getting drunk in order to forget, I mean running a Windows SDR application directly on OSX thanks to the Wine libraries.
Wine will allow running things like HDSDR or WinRad as fast as they would run in their native environment. In order to fetch data from the receiver one can use gnuradio, which is open source and available for the Mac. The remaining parts are gr-baz and the ExtIO DLL (the necessary "glue" to put everything together) that are provided by Balint Seeber.

At the end of the process, at the cost of hours of work and dozens of downloads, one can have a stable solution that is virtually Microsoft free. But what a pain! Since I realize that compiling code is not fun at all, I decided to try creating one easy solution, something that - in pure Mac style - the end user would simply install by "drag and drop"  without any other hassle. This is the end result:
