You could have used a Macbook for years, and still not know everything there is to know about all the neat tricks you can do with it. Some of these are just plain fun, others can be extreme time savers.

The holidays are over, and it’s time to finally take a closer look at our shiny new Macbook Air, Pro or iMac, we found under the Tree. One of the first questions a new Mac user might have, especially coming from a Windows PC or Linux background, is how to install software and apps.

With a Mac OS X device at our disposal, fitted with a FaceTime camera, is actually quite easy to sign a PDF document, as well as any other supported graphic formats, including PNG, JPEG, GIF and BMP.

So here we are tearing up the shiny, colorful wrapper, hiding a sleek, white box with some very familiar lettering. It’s a cool new Macbook! Question is: what to do first?
