Stop your Mac from going to sleep

As my regular readers over on Hardware 2.0 will know, I've now got a Mac. It's a Core i7-powered, Retina display MacBook Pro, and it is amazing!

It's a great portable system, and I use it for work, and for processing photos and videos.

Because the MacBook Pro is a portable system, Apple have optimized it for battery use, and this means that it goes to sleep whenever it thinks that you're not using it. This is great if you are trying to get the most from your battery, but at other times it can become a bit of a pain in the rear.

While I could dig through the settings and tweak them whenever I don't want the Mac to go off, this is hardly a handy set up, mostly because I forget to undo the changes, and then I hose the battery.

A simple solution I've discovered for this problem is a simple app called Caffeine. This is a freeware app that puts an icon in the right side of your menu bar, which, when you click it prevents your Mac from automatically going to sleep, dimming the screen, or firing up the screen saver.

Very simple, yet very effective, and well worth downloading.
