Hi Bill,
Further to the WSJT-X + Big Sur + M1 problem, three conclusions have been
reached following tests with my correspondent:
1. The M1 page size is 4k and not 16k
2. It seems that the M1 version of Big Sur does not get the shared memory
information from /etc/sysctl.conf
3. If kern.sysv.shmmax and kern.sysv.shmall are directly written to via
terminal commands (104857600 and 25600 respectively) then WSJT-X loads and
runs.
The snag here is that these kern.sysv values do not survive a reboot - although
this has to be tested. Next step is to find out how to set the shared memory
configuration in a permanent way. Tomorrow’s job…

Hi John,
that's good news. Does 'info sysctl.conf' from a terminal on an M1 macOS
11 system tell you how to proceed?
