On Mac the scroll bars can be hidden and only have them show when you scroll the page so you can see the current scroll position.

The idea is that a touch pad is used that doesn't require the scroll bars to be visible and thus have more screen estate for the browsing area.

You can make the scroll bars always visible:

System Preferences > General > Show Scroll Bar > Choose "Always"

Sorry, I guess I wasn't clear. The scroll bar is there. But the two arrows that were usually above and below it, are gone. Also I can't use my up and down arrow keys on the keyboard. The do nothing. When I use the scroll bar and my touch pad, it is too hard to control.

This is the result of having support for arrowless scroll bars on Mac Lion and later. You will have to drag the scroll thumb instead or use the keyboard if you do not have a scroll pad.

Oh, that is just a huge inconvenience. Thanks for the info though.

You're welcome.

I think the up and down arrow keys should work if the document has the focus and the cursor is not in a form field. You may need to tap a random area of the page to change that.

But I'm a Windows users, so things often differ...
