NSPasteboard.AccessBehavior.default
The default behavior for the General pasteboard is to ask upon programmatic access. All other pasteboards default to always allow access. If an app has never triggered a pasteboard access alert, its General pasteboard will report .default behavior. Such an app is not shown in the corresponding System Settings pane. Once programmatic pasteboard access triggers the first pasteboard access alert, the state automatically changes to .ask. At this point the app starts being shown in System Settings, where the user can toggle the behavior between .ask, .alwaysAllow, and .alwaysDeny.
