So I'm new to mac. Sometimes when browsing the web I get the spinning rainbow pinwheel when clicking on links or submitting stuff. WTF does this represent? IS it like the Hourglass for windows? My MBA is basically brand new but its done it since day one.
If I click off a hyperlink or submit buttons the pinwheel goes away and back to normal pointer.
