Found it yourself
The document that recommends building a GUI for OS X is called macOS Human Interface Guidelines . In the "Naming Windows" section there are no hard requirements. But a further reference to "The App Menu" clarifies the requirements. Namely:
If possible, use one word for the app menu title. Using your app's menus. If your app's name is too long, provide a short name that's about 16 characters or fewer. If you don’t want to know how to do this
Don't include the app version number in the name. Version information belongs in the About window.
Use the short app name menu items that display it. If you’re getting a quick app name, a short app name, and a quit menu items.
Thus, for OS X, the layout of the main window of the application needs to use only the name of the program (and preferably less than 16 characters).
The question is closed.
