Works on Linux/Gtk2. Maybe bug only appears on Carbon.

It seems that the same bug applies for every control with custom scrollbars. For example TSynEdit (run Lazarus, open new unit and make the source editor taller than the file content. Vertical scrollbar should disappear but stays).
Happens only on OSX/Carbon.

Under COCOA no scrollbars visible and ScrollBy don't work. So TScrollBar is not working on macOS. Any chance to fix this?

This solution work for me and CARBON:
