Description Patrick (volunteer) 2025-04-22 23:41:34 UTC 
Since macOS Sierra, macOS has the ability to support multiple NSWindows within a single NSWindow. NeoOffice implemented this feature a few years ago.

Snapshot of macOS "Prefer tabs when opening documents" preference

Native tabbed windows on macOS are controlled by the "Prefer tabs when opening documents" preference in the System Preferences application. The default setting is "In Full Screen" but in this snapshot, it is set to "Always" so that non-full screen windows also can have tabbed windows.

Snapshot of the EnableNativeTabbedWindows LibreOffice expert preference

For those who want to disable native window tabbing even when it is enabled in the System Preferences application, setting the "EnableNativeTabbedWindows" expert preference to "false" will disable native window tabbing.
