> Jiggler is a little freeware app with one purpose: to keep your Mac
> awake. When you have some lengthy task for your computer to do, it's
> annoying to have to turn off your screensaver and turn off the sleep
> timer, only to have to turn it all back on again when you're done.
> (The "never sleep" corner will keep your screensaver from kicking
> in, but still won't prevent your machine from falling asleep.) What
> you really want is a little helper who will bump your mouse every
> once in a while to keep your machine alert. That's Jiggler.

> Jiggler just wiggles your mouse every once in a while, keeping your
> machine awake and happy. When you want to stay awake, run it. When
> you don't want to, quit it. You can even run it while you're
> working, because you can set it not to wiggle your mouse unless your
> computer has been sitting idle for a while. Or you can configure it
> to:
>
> \- jiggle only when your machine is busy working, to make sure it
> doesn't fall asleep in the middle of a long job
>
> \- jiggle whenever an unburned CD or DVD is inserted, to make sure
> it doesn't fall asleep while burning
>
> \- jiggle whenever iTunes is playing, so your music doesn't get
> interrupted
>
> \- jiggle whenever a particular application is running, if there's
> an app your machine needs to stay awake for!
