The maximum number of items that may be presented in the standard Open Recent menu.
- macOS 10.4+
A value of 0 indicates that
NSDocument will not attempt to add an Open Recent menu to your application's File menu, although
NSDocument will not attempt to remove any preexisting Open Recent menu item. The default implementation returns a value that is subject to change and may or may not be derived from a setting made by the user in System Preferences.
