NoSleep is an application that you use to prevent your Mac from going to sleep and for waking it at a specified time and then keeping it awake.

This app 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.

What can NoSleep do for me?

  • Keep you Mac awake for a given period of time. NoSleep updates system activity periodically as soon as it launches, until it is quit, or the battery charge level drops below a specified amount (which defaults to 10%)

  • Wake your Mac at a specified time. NoSleep can be used to wake your Mac on a one time basis at a specifc date and time.

    As soon as you launch NoSleep it prevents your Mac from sleeping until quit, or the battery charge level drops below a specified amount . 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 Mac to sleep, and then have NoSleep automatically wake the Mac and still quit at the specified time. This feature requires that NoSleep runs as root, which can be accomplished using our app Chalaut, a "run as root" app launcher. Do this in Preferences.

    Preferences Window:

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

    Also use the text field on the preferences window for creating a timer to quit the app at a time you can specify as a (fractional) number of hours. The timer is created as soon as you change the value of the text field, and each change resets the timer. If the value of the text field is zero no such timer is created, and any previous such timer will be removed.

    Finally, in preferences you can specify a battery threshold so that NoSleep stops keeping the Mac awake at a certain level. This helps prevent the Mac from running out of energy when unplugged.
