Always Show Scroll Bars in Mac OS X
The scrollbars in new versions of Mac OS X are hidden until activated by use, that is, by scrolling, making them invisible by default. This is the new default behavior that works very well if you primarily use a trackpad with your Mac. I use an external mouse with my Mac quite often though, and I find the hidden scrollbars to be annoying when I do. That’s my reason for bringing them back, but other people just like to see when content is available that needs to be scrolled to access.
This quick tip will make users who wish to constantly see available scrolling portions happy, by displaying the scroll bars all the time in Mac OS X.
