Hi Steve: Thanks for you thoughts!
I did do John, G4KLA's procedure quite some time ago when the Mac Mini first came on line (as it was necessary). I have reviewed that again, and the values haven’t change on the Mini, (or the desktop and laptop which are working fine with OS 10.13.6). My results are: $ sysctl -a | grep sysv.shm kern.sysv.shmmax: 33554432 kern.sysv.shmmin: 1 kern.sysv.shmmni: 128 kern.sysv.shmseg: 32 kern.sysv.shmall: 8129 The is significantly larger that what is working for you (although the last line is smaller), and the error message is not the same as one that the current message is producing. My next step seems to be ripping out 10.14.2 and drop back to 10.13.6, and see if that even has anything to do with it. 73, Jim K6MIO/KH6 > On Dec 20, 2018, at 12:02 PM, Steven Franke via wsjt-devel > <wsjt-devel@lists.sourceforge.net> wrote: > >> I seem to recall that there was a point, previously, during which some Macs >> needed to have a memory range tricked out.
