The Caffeine applications does not require users to go to the power saver area within the System Settings in the Mac desktop to change the settings on the computer. This version is particularly useful for those who want to view a video or YouTube video while they don't have to physically tap the keyboard or touch the mouse to open the screensaver. Instead, all the work can be done with a few simple mouse clicks. The most notable benefit for this application is that it can be used with any version of Mac OS X. As such, it is available for both the Classic and the newer Leopard.
While the primary function of the Caffeine app is to allow the user to play a YouTube video or a video from a photo gallery directly from the Mac's clipboard, it also has additional features that make this experience more interesting. The built-in screenshot tool allows the user to take a snapshot of whatever the screen is currently displaying. It also provides support for a large number of commonly used commands that allow you to work with your Mac as if you were in a fully functional internet browser. Some of these commands include Go to, Home, Close Help, Quit, Restore, and a host of others.
The Caffeine app serves a dual purpose for Mac owners. For those who use the computer at night and need a little bit of a pick-me-up to get them prepared for a day of productive work, the built-in sleep manager makes sure that the computer is properly set to save energy when needed. It also helps you save battery life so that Macs do not have to be put on sleep mode for long periods of time. In addition, the built-in calendar and clock widget make it easy to set recurring events for the Mac's built-in alarm system. And because Caffeine can be used as an energy saver, the clock widget makes it easier to see which of your many activities are keeping your computer from sleeping.
