Keep your Mac from sleeping with Caffeine!

There are some times — like when you’re watching a DVD movie or burning a DVD with iDVD — that you don’t want your Mac to sleep. Sure you can open the Energy Saver and/or Desktop & Screen Saver System Preference pane and make your adjustments there, but wouldn’t it be nice if you could suspend both — sleep and screen saver — with a single click? 

Well you can. All you need is a copy of Caffeine, a freeware application from Lighthead Software. Launch Caffeine and a little coffee cup icon appears in your menu bar, like this:

To turn Caffeine on and stop your Mac from using its screen saver or sleep temporarily, just click the coffee cup icon in the menu bar and it will fill with coffee to let you know it’s turned on, like this:

To change the default duration Caffeine is enabled, Command + click the coffee cup icon in your menu bar and make your selection from the Caffeine menu that appears, like this:

How can you not love that? It’s free, it’s easy to use, and it’s handy as all heck!

    I downloaded caffeine and now I can’t get rid of it. When I put it in the trash it says it can’t dump it because it is in use. How do I get if to turn off. Command click does not bring up the menu,

    Mickey,

    When I Command+click the Caffeine coffee cup in the menu bar I see a menu with a Quit command… Does that not happen for you?
