Best Mac OSX / WSJT-X Configurations?

Mac Mojave, SDR Version 2.49, Flex 6600 here.  Trying to configure OSX version of WSJT without success.

I know there have already been articles on setting up WSJT on a mac.  I have tried them all without success.

For CAT, I have tried xCat,  MacLogger DX, and JT Bridge.  xCat only had ports versus only IP addresses on the WSJT side with Flex Radio selected as the rig.  DX Commander via MacLogger DX kind of works, but always wants to start up a second slice and make it the RX slice??  Tried JT Bridge.   Could not figure out how to make it work?

For audio, I configured Sound Siphon per the outdated instructions from George Mulnar, KF2T.  My version of Sound Siphon must be a revised / newer version.  I could see Sound Siphon in the Mac audio inputs, however I could not see Sound Siphon in the audio outputs, both in system preferences.  I could not see any Sound Siphon selections in WSJT audio settings.  Started up xDAX and got audio into WSJT from the selected slice, but have no idea how it worked?

So......for those of you are today, successfully, using your OSX version of WSJT-X on a mac, please share as much detail as possible on your configuration.  I am not wedded to any single solution.

Hi there,

just to chime in here.. There is good and bad news.. The good news is that I could find some time to start making xCAT and xDAX work with SmartSDR v3 (and v2.5.1). The bad news is that I'll have to leave for some work commitment this Saturday and will be away from the radio for 6 weeks.. :-(

So it still might take a while until the new versions are ready..

Sorry and thanks for your patience..

Try  for a solution that works for 2.5 and 3.0, and even MacOS Catalina.

Great tutorial, George - it should really help out those who have moved up to v3.

One caution / caveat / fly in the ointment: in High Sierra (at least) there is a bug in kext installs (the sound pseudo-device drivers are kernel extension) that can prevent the “allow a new kernel extension to load” step to not be found.

When High Sierra MacOS loads a new kernel extension, the “Security & Privacy” control panel may need to be visited to allow the load. The “Allow...” button in that control sometimes does not “see” the mouse click, and will not show you the list of extensions to be allowed. In order to get around this, you need to enable "Full Keyboard Access. > All controls” in “System Preferences>Keyboard>Shortcuts”. After this, go to the “Security & Privacy” control, use “Tab” to get to the “Allow...” button and use “Space bar” to “click” it. You can then allow the load. You can also do this through keyboard action by turning on accessibility controls.

See “” for an example.

I know it’s a pain, but it happened to me (probably because I use “Magic Prefs”, a Magic Mouse extension).
