In 2011, Mac OS X 10.7 removed the buttons from the end of the bar and was designed to look more like the iOS scrollbar. With the same release of Mac OS X 10.7, Apple introduced “natural scrolling,” which means that the screen moves in the same direction as the user’s fingers are moving when they use the two finger scroll gesture. If the user’s fingers move up the trackpad, the content on the page goes up, allowing the user to read content further down the page, and vice versa.
