Caffeine: Stop your Mac from going to sleep

You’re watching videos on YouTube or TV shows on Hulu, and your Mac just keeps wanting to go to sleep. You’d rather not open System Prefs to change Energy Saver settings as you’ll just have to reset them again when you’re done watching.

Caffeine puts an icon in your menu bar for on-the-fly access to your Mac’s Energy Saver time out settings. It’s free, super useful and, well, it’s free.
