NoSleep For Mac

NoSleep is a very easy to use application that allows you to keep your computer from going to sleep and waking it at a specified time.

Using the Preference pane to specify quit time and wake time you can keep your computer awake for a specific interval of time.

NoSleep was conceived for musicians who use their Macs to read music as they play their instrument and consequently do not want their Mac to go to sleep.

As soon as you launch NoSleep it prevents your computer from sleeping until quit. You can schedule the time it quits so that you can leave it unattended. Do this in Preferences.

Additionally you can launch NoSleep, force the computer to sleep, and then have NoSleep automatically wake the computer and still quit at the specified time.

This feature requires that NoSleep runs as root, which can be accomplished using the app Chalaut, a "run as root" app launcher. Do this in Preferences.
