Some people might be getting a new Mac this holiday season, so we’re offering 20% off our Video Guide To Mountain Lion. We put together 20+ videos with more than 2 hours of instruction, and made it super-easy to get by putting it in the Mac App Store.
This is a great way for beginners to get to know Mac OS X Mountain Lion, and for casual users to dig deeper into the features. The videos are unique, not something that can be found anywhere else. The app lets you jump easily from video to video and you can resize the window for better viewing, even going full screen.
Even if you are proficient in using OS X, you may want to consider recommending this to friends as a good way to jump in and learn more.
