In macOS System Preferences->General you can change "Prefer tabs when opening documents" option to "never" or "always" etc.

I would like to enable this feature for all apps but LiveCode, so I need to know the shell command to change this option to "never" or to "always", so I can use it on activating/deactivating the app.


You don't need to keep changing the Global Preferences: you can set the preferences per app with:

defaults write -app LiveCode AppleWindowTabbingMode -string manual

Other options to try include never, always, and fullscreen.

The app should not be running when you edit the plist.
