the mac issue is with window focus… if calling from ‘Ruby Console’ you need to close it… ```ruby # move focus to SU viewport by closing RC. SKETCHUP_CONSOLE.hide Sketchup.send_action('selectPaintTool:') # or for one of my own tools I may use # Sketchup.active_model.select_tool(JcB::Selector.new) ``` if triggered from a menu item or a `UI::Toolbar` it should change, so I assume your using a Web or Html dialog… moving focus from these is harder unless you simply close it. i.e. `@my_dlg.close`… the alternative is to ‘toggle’ a separate dialog… ```ruby NODLG = UI::WebDialog.new('noDlg', false, '', 0, 0, 0, 0, false) unless defined? NODLG # move focus to main window... def de_focus NODLG.show NODLG.close end ``` then you can call `#de_focus` after triggering your tool… john --- _[View the full topic](https://forums.sketchup.com/t/cursor-doesnt-change-on-mac-when-activating-a-tool-from-ruby-api/60921)._
