A while ago I already managed to compile gqrx on OS X, but then Alexandru Csete decided to move on to a new audio backend called pulseaudio. Sadly there is no proper pulseaudio port for OS X. Thus I bring you my branch of gqrx 2.1 which runs quite well on OS X.
This release bundles all the rtl-sdr, gr-osmosdr, GNU Radio, libUSB, boost and Qt dependencies allowing it to work out of the box. Though feel free to contact me in case you encounter problems. It has been reported to run fine on Snow Leopard (10.6), OS X Lion (10.7), OS X Mountain Lion (10.8) and OS X Mavericks (10.9). Sadly Leopard (10.5) isn’t supported due to Apple breaking binary compatibility on 64bit binaries for some reason.
Download the ready to use DMG/APP here:
gqrx_8.dmg – (07/01/2013) Latest GIT. Some people are reporting FFT issues with this build, in case you encounter those try the one below and leave a comment. (shasum: 66b9f6952aff5cb0bc995556c633b3cc7f5d990e)
gqrx_7.dmg – (02/03/2013) Up to date with GIT. I’ve added a deadlock prevention feature in case your settings keep gqrx from starting up properly. After a crash/forced-close it asks you whether you want to reset all your settings to default. This should help you guys with invalid rtl_tcp settings and the like. I have also fixed rtl_fm to now properly work on OS X (It used to only output noise), as well as multimonNG which now supports umlauts for POCSAG decoding. So check out the bundled command-line utilities! 🙂 (e.g. /Applications/Gqrx.app/Contents/MacOS/rtl_test -t)
gqrx_6.dmg – Latest (01/16/2013) updates from GIT, yet again. This time I also packaged some command-line utilities (multimonNG rtl_adsb rtl_eeprom rtl_fm rtl_sdr rtl_tcp rtl_test) together with Gqrx. rtl_fm seems to be broken on OS X, yet we’re still triaging the bug. It would be great if you could try it and report whether it works for you. (http://kmkeen.com/rtl-demod-guide/index.html) I am considering packaging up the whole of gnuradio including the companion GUI if there is demand.
gqrx_5.dmg (Latest updates from GIT, supports adjusting the FFT resolution which should fix the pink curtain problem. The zoom slider has been removed from upstream, yet you can still zoom by using the mouse wheel on the axes.)
gqrx_4.dmg (GNU Radio component has now been compiled with “-DTRY_SHM_VMCIRCBUF=OFF”, this should hopefully fix the shared memory problem some of you have encountered. Please report whether it works now.)
gqrx_3.dmg (Rebased to the zoom branch. Credit goes to vpelletier for the awesome patch!)
Pan: left-click on X-axis labels & drag horizontally
Pan (alternative): Mouse wheel on X-axis labels, faster pan with Shift held and slower pan with Ctrl held.
Change central frequency: middle-click on X-axis labels & drag horizontally
Zoom: slider on FFT panel
gqrx_2.dmg (Updated gr-osmosdr and fixed a crash when disabling demod.)
The screenshot was taken in direct sampling mode, that’s why I was able to receive 0-2.4mhz. I’ll probably blog about my modded dongle soon.
I just took my test today and I got my Tech license — I got into this for the SDR stuff and competing. I want to help you test or do anything I can. Feel free to contact me.
Thanks for the great work.

Hi, I tried to install the most recent and the one before that version of GQRX and I am getting a message that it will not run on my type of mac. I don’t understand as ~I thought my machine would be powerful enough for sdr. Maybe it is asking a bit much of my machine but am I doing anything wrong?. It is a 1.83 GHz Dual Core with 2GB of ram. The OS is Snow Leopard. Please let me know if it can. I am pretty new to OSX.
Maybe your machine doesn’t support 64bit operation? Please tell me the CPU model.
I’ve just started trying to use your port with the NooElec R820T but I received an error message with both versions 7&8.
I’m running on osx10.9.2 a macbook with 2.7ghz i7processor.
Here’s the specifics to the application exception:
Exception Type: EXC_CRASH (SIGABRT)
Exception Codes: 0x0000000000000000, 0x0000000000000000
Application Specific Information:
terminating with uncaught exception of type boost::filesystem::filesystem_error: boost::filesystem::create_directory: Permission denied: “/Users/Zack/.gnuradio”
hope you can help out as I’d love to try out your port and not have to dualboot
Looks like it tries to create a settings/configuration directory and fails due to lack of permissions.
I suggest to create it manually (“mkdir /Users/Zack/.gnuradio” in Terminal) and make it writable
I’ve had lots of problems using Brew and MacPorts to get working gnuradio. I’m most interested in using gnuradio-companion as I’d like to decode AIS signals. You mentioned in your blog post you’d consider a full package for gnuradio with the companion, can I request that you consider it?
On a separate note, I am unable to record audio as GQRX crashes each time, and the build you have compiled does not contain the network element as I would quite like to stream the audio to process using aismon on Windows if I cannot find a suitable OSX package.
Thank you for your contribution, I’m really enjoying toying with SDR
Unpackaged my R820T SDR not even 15 minutes ago, installed your port on my Mac, and I’m playing local radio! Works great!!!!
How did you configure it? The options given to set up RTL-SDR Spectrum Server, Complex Sampled (IQ) File and Other don’t work with my NooElec R820t@ & DVB-T NESDR Mini 2 dongle.
Is there any chance of a bundled build of the latest snapshot?
I’ve been trying the Macports route with little success, mostly as it breaks the setup I need for work, which is tied heavily to Homebrew, so finding your bundles was great – but the problem I have needs verification on the latest snapshot before I start reporting bugs to Alex.
Tried both files with os x mavericks and the program would not load, hat to force quit.
Awesome! For me gqrx from git just wasn’t working properly, but your port worked straight away!
Yup, spot on – FFT issues within ‘gqrx_8.dmg’.
With the FFT size held at 4096, any Rate – including 50fps – is ‘happy to-play-ball’ all day long.
Selecting anything higher than 4096 is only possible by backing the Rate down somewhat.
(For me, an FFT size locked at the maximum of 16384 – demands that the Rate chosen is no higher than 25fps, and even then it’ll still occasionally lock up. When running an FFT size of 16384, I can only attain a rock-steady-stable-state – with the Rate locked at 20fps.)
Running Lion v10.7.5 on a MacBook (Late 2007), 2.0GHz Intel Core2 Duo with 2GB 800MHz DDR2 RAM…
So, I’m gonna ‘nudge another smack of encouragement’ at urging Elias to go ALL-IN!
C’mon, you know we all want it – give us GNU Radio on OS X…
On which way can I use the funcube pro with these software
What need I to do to get I working
Sorry I have give you a wrong email address
But what need I to do to get Gqrx running with funcube pro dongle
With RTL28xx dongle it running fine
Any plans to update your dmg for the latest gqrx release, 2.3? Right now, the only way to install it is macports, which comes with its own costs.

Using this with Yosemite 10.10.1 it needs the dongle to be plugged in first and then it seems to install correctly. Installing it without the dongle it throws 2 errors and freezes on first run. The trick is to install it again with the dongle plugged in and this seems to help. I have it on 2 Macbook airs 2010 2011 and it works on both
I followed Stan’s advice and it worked. FM radio reception only, so far. The AM freq are limited.
Yosemite 10.10.5. NooElec RB20T SDR.
I have an SDR that supposedly can receive 100kHz to 1.7 GHz, but can’t seem to hear HF with this port of GQRX.
How do I enable direct sampling mode?
I think if you leave the tuner in place you have to add “direct_samp=1” to the device string. Since I have removed the tuner on my dongle it always comes up in direct sampling mode.
Any ideas how to zoom in on the signals on a macbook? There is no scroll wheel and I’ve spent ages trying to find a way. Same with my iMac which has a touch sensitive mouse. Again no scroll wheel. Don’t understand why there is not a keyboard shortcut or a slider bar.
No Mac mouse seems to work with this, and the trackpad is no help. The up/down cursor keys work on highlighted digits, and the left/right ones [or trackpad/mouse] can be used to select the required digit. The solution is simple, although a bit inconvenient: I’m using an ordinary PC USB mouse with scroll wheel, it works fine for me in OS X 10.10.4 Beta [and was also fine in OS X 10.8 and 10.9] on a 2012 MBP 9,1.
I hope that this helps?
On your trackpad, you should be able to do two-finger scrolling. There is also a scrolling behavior in your touch-sensitive mouse. There are little videos on the system preferences page for each device that will show you how to do this. Whatever you do with them to scroll up and down a web page will work in any program and be indistinguishable from a physical scroll wheel on a mouse.
I’ve been trying to use your port, but it’s been crashing due to an error on the objective C garbage collector.

Thanks for the excellent work, Elias.
Do you have any news about a build based on version 2.3, yet, please? I cannot get it to compile and run from the gqrx.dk website, and don’t know how to correct the errors.
I forgot to add that the relevant gqrx.dk blog pages login process will not work for me, so a direct request to Alex cannot be made. :-\ Is anyone else having the same problem?

Do (have?) any of your versions supported the Apple PowerPC computers?
No, I’ve never owned any PowerPC system and Apple surely doesn’t make it easy to build for those.
Any chance these come with a checksum or GPG signature?
I’ve added a sha1 hash for the latest build. (shasum)
MAX OSX. multimon-ng
Downloaded the multimon-ng and got to compile. Is there a way to build it ot use the SCOPE or xdiplay? Looks like it is removed? Kind of new to all this SDR and also mac. Not sure if I am not doing something correctly or what can be done etc.
The newer versions of OS X got rid of their X server. You have to install a third party X server and enable support in the qmake-file.
Thanks this allows me to run my SDR bundle on my Macbook Pro as well as my HP Elitebook. Love this mac so much I almost hate starting the HP to do any work that isn’t available on the Mac. More and more I am finding ways to transfer my chores to my aging Macbook Pro, and ya she is a bit slow with only a core2 duo processor and 2 gb of Ram, where my HP has a i7 processor at 3ghz with 16 gig of ram. Still the Macbook runs way smooooooother, so now I can add my SDR package to the Macbook and still not have to fire up the HP and struggle with all the damn advertising and updates that Windows 10 keeps pushing at us on an almost daily basis.
Will GQRX run on Apple High Sierra V 10.13.4.? I am not having any luck with catching radio signals.
ive had it running on the cheap rtl or whatever dongle since this old dead thread in 2014.
just upgraded to high sierra latest. works as always. i did fool around with the command line stuff to get it working 4 years ago just posting so say don’t fear an OS upgrade will break it.
resisting mojave for now. MacBook Pro late 2013 .
