iWillQuit

This is sure to save your laptops hard drive. If you have a network in your house, schedule it to download files at night so as to not slow down others using the network or to keep your VOIP working without delay. Apple’s scheduler will not shut down/sleep while there is an internet radio stream, but iWillQuit does. iWillQuit works just as it said it does, shuts down, sleeps, etc. Link
