Trajectory runs fine for me on a Mac.
JVERSION
Engine: j901/j64avx2/darwin
Beta-m: commercial/2019-10-02T11:28:59
Library: 9.01.08
Qt IDE: 1.8.3/5.12.3
Platform: Darwin 64
Installer: J901 install
InstallPath: /users/bobtherriault/j901
Contact: www.jsoftware.com
I note that the Qt IDE and the libraries differ from Gilles, but this would be
natural for a different operating system, right?
Cheers, bob
