Notes on WSJT-X Installation for Mac OS X

If you have already downloaded a previous version of WSJT-X then I suggest you change the name in the Applications folder from WSJT-X to WSJT-X_previous before proceeding.

I recommend that you follow the installation instructions especially if you are moving from v2.3 to v2.4 or later, of WSJT-X or you have upgraded macOS.

Double-click on the wsjtx-...-Darwin.dmg file you have downloaded from K1JT's web-site.

Now open a Terminal window by going to Applications->Utilities and clicking on Terminal.

Along with this ReadMe file there is a file: com.wsjtx.sysctl.plist which must be copied to a system area by typing this line in the Terminal window and then pressing the Return key. 

sudo  cp  /Volumes/WSJT-X/com.wsjtx.sysctl.plist  /Library/LaunchDaemons


  • You will be asked for your normal password because authorisation is needed to copy this file.
  • (Your password will not be echoed but press the Return key when completed.)
  • Now re-boot your Mac. This is necessary to install the changes.
  • After the reboot you should re-open the Terminal window as before and you can check that the change has been made by typing:
sysctl -a | grep sysv.shm


  • If shmmax is not shown as 52428800 then contact me since WSJT-X might fail to load with an error message: Unable to create shared memory segment.
  • You can now close the Terminal window.
  • It will not be necessary to repeat this procedure again, even when you download an updated version of WSJT-X.
  • It might be necessary if you upgrade macOS.
  • Drag the WSJT-X app to your preferred location, such as Applications.

Audio Configuration

  • You need to configure your sound card.
  • Visit Applications > Utilities > Audio MIDI
  • Setup and select your sound card and then set Format to be 48000Hz 2ch-16bit for input and output.

Preferences

  • Now double-click on the WSJT-X app and two windows will appear.
  • Select Preferences
  • Under the WSJT-X Menu and fill in various station details on the General panel'.
  • I recommend checking the 4 boxes under the Display heading and the first 4 boxes under the Behaviour heading.
  • Depending on your macOS you might see a pop-up window suggesting that wsjtx wants to use the microphone.
  • What this means is that audio input must be allowed. Agree.
  • Next visit the Audio panel and select the Audio Codec you use to communicate between WSJT-X and your rig.
  • There are so many audio interfaces available that it is not possible to give detailed advice on selection.
  • If you have difficulties contact me.
  • Note the location of the Save Directory.
  • Decoded wave forms are located here.
  • Look at the Reporting panel.
  • If you check the "Prompt me" box, a logging panel will appear at the end of the QSO.
  • Visit Section 11 of the User Guide for information about log files and how to access them.

Finally, visit the Radio panel. WSJT-X is most effective when operated with CAT control. You will need to install the relevant Mac device driver for your rig, and then re-launch WSJT-X. Return to the Radio panel in Preferences and in the "Serial port" panel select your driver from the list that is presented. If you do not know where to get an appropriate driver, contact me.

WSJT-X needs the Mac clock to be accurate. Visit System Preferences > Date & Time and make sure that Date and Time are set automatically. The drop-down menu will normally offer you several time servers to choose from.

On the Help menu, have a look at the new Online User's Guide for operational hints and tips and possible solutions to any problem you might have.
