WSJT-X updates and Mac problems

posted 6 Mar 2021, 06:27 by Mike Brown
Joe Taylor and team have released a second release candidate for version 2.4.0, which includes the new Q65 mode. Separately there is a new full release, version 2.3.1 due out on Monday 8 March. See https://physics.princeton.edu//pulsar/k1jt/Release_Notes.txt for details

According to posts on the WSJT-X io group the recent Mac problems are due to undocumented changes to the Mac operating system. The issue appears to be down to new restrictions on programs sharing memory access. This is essential for WSJT-X because it runs as two separate sub-processes, called jt9 and wsprd. The WSJT-X team are planning a re-write but this is a major task, so not likely to be quick. The only other hope is that Apple improve the documentation of sysctl parameters.
