PleaseSleep is a utility software designed for Mac OS X that helps put your computer to sleep when you know some other app is preventing your Mac from going to sleep.

PleaseSleep sits in the background and waits for the sleep timer you set in Energy Saver preferences pane. Depending on the preferences you set, PleaseSleep will try to put your computer to sleep when the scheduled sleep timer kicks in. PleaseSleep is very easy to configure, you can enable, disable, and access its preferences via the system menu bar icon. You can choose to have PleaseSleep activate the sleep function all the time, or you can tell PleaseSleep to activate the sleep function only when certain apps are running.

PleaseSleep is freeware. However, if you enjoy using PleaseSleep and would like to help support its development, please consider making a donation.
