When it's time to leave your Mac for a while, you want a nice quick way of putting it to sleep and a little bit of flexibility in how you do it.
Introducing Midnight, a Dashboard widget designed to help you put your Mac to sleep in the way you want and at double speed.
Midnight can either put your Mac into its standard sleep mode or into hibernation mode (also referred to as 'safe sleep' or 'deep sleep'). Standard sleep is where your Mac reduces its power consumption to a minimum by stopping its processor but maintaining the supply of power to (and thus maintaining the current contents of) the RAM. Hibernation is different in that no power is used at all. In order to do this your Mac will copy its current RAM contents onto its hard disk. It needs to do this so that it can remove power from the RAM and keep a copy of its contents for when you want to wake your Mac up later.
