Hi, I’m developing a macOS Finder Sync extension and noticed that NSMenuItem.separator() does not appear to render as a standard separator line when used inside the menu returned from FIFinderSyncController. In a normal AppKit NSMenu, the separator renders as expected. However, when the same kind of menu is returned from the Finder Sync extension, the separator appears as a blank/full-height empty row rather than a thin dividing line. Example: override func menu(for menuKind: FIMenuKind) -> NSMenu { let menu = NSMenu(title: "") menu.addItem(NSMenuItem( title: "First Action", action: #selector(firstAction(_:)), keyEquivalent: "" )) menu.addItem(NSMenuItem.separator()) menu.addItem(NSMenuItem( title: "Second Action", action: #selector(secondAction(_:)), keyEquivalent: "" )) return menu } Expected result: The separator should render as a normal macOS menu separator line between the two menu items. Actual result: In Finder’s context menu, the separator is displayed as blank vertical space / an empty menu row. I understand that Finder Sync menus are rendered by Finder and may not support every NSMenuItem feature. However, NSMenuItem.separator() is a very standard way to visually group menu commands, so I wanted to ask: Is this a known limitation of Finder Sync extension menus? Is there a supported way to display a real separator line in Finder Sync context menus? Should this be filed as a Feedback Assistant issue against Finder Sync / AppKit? I’m trying to avoid fake separators such as disabled menu items with "────" as the title, since that does not feel native and may not behave well with different fonts, accessibility settings, or appearance modes. Thanks!
