We tend to spend most of our time focusing on the big stuff in life. I used to have a paralegal who was a tough as nails ex-Army guy fond of saying, “ya gotta fix what’s killing ya first.”
Despite the obvious, if a bit alarming, wisdom of this advice, sometimes it’s the little things in life that matter most: a courteous driver letting you merge into hellish traffic; a hand-written thank you note; Jon Stewart and the 2012 Republican primaries.
Caffeine does one thing and does it simply and well (the app, that is – the stimulant does a host of delightful things): when you click on the little coffee cup icon in the menu bar, it prevents your Mac from going to sleep, dimming the screen or starting screen savers. It is, in essence, a little master switch so you don’t have to go digging around in System Preferences to set the Energy Saver.
It works beautifully for presentations and any other time that you don’t want your Despair, Inc. screen saver popping up.
