When i comes to this problems, I always delete the settings from the app.
Sadly I don't know where WinBox hide's it's settings on the MacOS version.
On my Arch Linux Install, when I start Winbox from the command line I get some hints where it stores the settings.
[patrik@archlinux mikrotik]$ ./WinBox
APP,INFO: version: "4.0beta30"
APP,INFO: loading addrs db from: "/home/patrik/.local/share/MikroTik/WinBox/Addresses.cdb"
APP,INFO: loading ok
APP,UPDATE: version fetched: "4.0beta30"
APP,UPDATE: nothing to update
APP,INFO: app about to quit
PERS,INFO: saving data to "/home/patrik/.local/share/MikroTik/WinBox/settings.cfg.viw2"
Maybe you can do the same from terminal, to get the info.
