One of the great features of the fourth-generation Apple TV is the built-in “Aerial” screen savers: gorgeous flyover videos of major cities, landmarks, and natural wonders. While these videos do indeed look great on your TV, wouldn’t it be nice if you could enjoy them on your Mac as well?
There may be times when you don’t want the OS X login screen saver to kick in. This might apply when, for example, the screensaver engine is acting up, and you don’t want it to activate, ever. John shows how.
