Mac OS X app : Caffeine by lighthead
Caffeine is a little app that sits in your top menu bar and will keep you Mac awake no matter what your energy settings are. One click turns it on, one click turns it off and you are back to your energy settings. I love this app because I am pretty aggressive with my energy settings and there are times I don’t want my Mac to sleep. Just stay awake! This little app keeps me from having to open system preferences and change my settings back and forth. Love it!
