Hi Jim, You may need to increase the shared memory allocation if you are running the stock configuration of MacOS. The instructions can be found in src/Darwin/ReadMe.txt file, which was prepared by John, G4KLA. Here’s a relevant excerpt from that file: '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 14680064 then ... WSJT-X will fail to load with an error message: "Unable to create shared memory segment”.' Here’s what I get on this laptop, which is running MacOS 10.14.2 and which runs WSJT-X just fine: $ sysctl -a | grep sysv.shm kern.sysv.shmmax: 14680064 kern.sysv.shmmin: 1 kern.sysv.shmmni: 128 kern.sysv.shmseg: 32 kern.sysv.shmall: 17920 If your shmmax parameter is smaller than 14680064, I recommend that you follow the procedure that is explained in the ReadMe.txt file.
