I always knew that coffee is my lifesaver

I guess every Mac users know the problem: You’re talking with your friends, showing them some drawing, snippet of code or website, talk even more with them and your Mac activates its screensaver and locks down the Keychain. For me that results in entering my password three times (one for login, one for iScrobbler and one for Safari’s Keychain access). Annoying.

But I discovered (or merely googled) a small tool which prevents your Mac from activating the screensaver, dimming down the screen or even going to sleep: Caffeine. Trust me, you need this tool.
