Running Dorico Pro 3.5 on macOS Mojave 10.14.6 (with valid USB license)
Problem: Dorico simply will not start. Upon attempting to start it, the initial “Dorico Pro 3.5 Advanced Mucic Notation System” logo box (white lettering on black) is displayed, but thereafter nothing happens: the hub does not open and the program does not start.
I have tried reinstalling it (using freshly-downloaded Dorico_3.5_Installer_mac.dmg file), but that has not helped.
