There are times when I want my Mac to not go to sleep or even start the screen saver. These of course are settings that you can change in your Mac system preferences as I have discussed previously. The problem with that of course, is when you change the settings for a temporary reason, you have to change them back again. First world geek problem as it may be, it is still annoying and in my opinion just screams for a small, well written application to step in and save the day but in an inconspicuous manner. Let me introduce you to, Caffeine!
The name of this little application is spot on! If you are starting to run low on energy and need an extra, though admittedly temporary, boost one of the things you may reach for is a hot steaming caffeine filled cup of hot brown. Well, the creators over at Lighthead Software were thinking along those same lines when they created one of the neatest little utilities called Caffeine.
