Set the category under which your macOS app will be listed on the Mac App Store. The category you select should match the category you later select in App Store Connect. For more details on app categories, go to App Store Connect Help.
Note: iOS, tvOS, and watchOS app categories are set in App Store Connect only.
In the project editor, choose the target, click General, then reveal the Identity settings.
Choose the category from the App Category pop-up menu.
