Application that you use to prevent your computer from going to sleep and for waking it at a specified time and then keeping it awake.
NoSleep is an application that you use to prevent your computer from going to sleep and for waking it at a specified time and then keeping it awake.
This app was written for musicians for when they use their computers to read music as they play their instruments and don't want their computer to go to sleep.
What can NoSleep do for me?
- Keep you computer 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 computer at a specified time.
NoSleep can be used to wake your computer on a one time basis at a specifc date and time.
As soon as you launch NoSleep it prevents your computer 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 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 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 computer 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 computer awake at a certain level. This helps prevent the Mac from running out of energy when unplugged.
This article discusses two different apps but calls it one. No sleep by limit point is commercial and costs 10 dollars and will not prevent computer sleep with lid closed. No Sleep by Prokofiev is freeware and allows the computer to stay awake with the lid closed. The badge displayed in this article is the Prokofiev badge but the user interface described is for the Limit Point program.
