Prepping for Mountain Lion: three steps you must take

This week Apple will be unleashing the Mountain Lion: Apple OS X 10.8, and aside from grabbing $20 from your dresser drawer, we've got three steps you'll want to take in preparation for this upgrade to your computer. This software update is set to bring you everything we got a look at a few weeks ago in our first Mountain Lion hands-on and more, and all of it for a cool $19.99 - but not everyone can join in on the fun. The first step you'll need to take is checking to make sure your machine can handle the update.
