Remember that tip, way back in 2012, where we showed you how to use the “caffeinate” command in the Terminal to prevent your Mac from sleeping for a specified amount of time? Well, it’s a new year, and with that comes a new way to keep your Mac from sleeping.
Sleep No More is a free app for your Mac that allows you to set a specific duration to postpone your Mac’s regularly scheduled sleep time. It’s a simple, graphical way to make this happen, without all that Terminal stuff, as it’s a nice little menu bar app.
There are bound to be times when you would like your OS X Mountain Lion Mac to not go to sleep. You can set you Mac to Never sleep in the System Preferences, Energy Saver preferences pane, but that’s not always going to work. Even when it’s set to Never, your Mac may still, in fact, go to sleep. The other problem with the Energy Saver preference is that you only have the ability to set the sleep action to hold of foor three hours, or never. What if you wanted to keep it from sleeping for four hours? Or four and a half hours? Or eight hours?
With a neat little Mountain Lion-only Terminal command, you can set it to whatever you like. Here’s the scoop.
