Programme layout of Sketchup

I would like to be able to have my plugins and toolbars to snap to the SketchUp layout instead of hovering around. This happens automatically on SU for Windows, but doesnt seem to work on SU for Mac. Can I somehow enable this?

You can create a toolbar across the top of the window but other toolbars and the windows don’t snap on the Mac like they do on Windows. There is no setting to make that happen.
