It's annoying when you are performing a download server does not allow a pause (like Megaupload or Rapidshare) and your Mac falls suspended (sleep) with the result that you have to start the download again from scratch and a good whack at the keyboard of courage . Worse still when you're enjoying a video on Youtube (or similar) full screen and your beautiful screen saver comes up appear.
Caffeine is a small utility for Mac OS once installed resides with the system clock. Just give a click on it and avoid the suspension system, the screen saver starts or turns off the monitor so you can watch video after video and not worry about your screensaver starts.
Caffeine is completely free and you can download from the official website of the program.
