Lion (Mac OS X 10.7) is now available, and unlike previous versions of the Mac OS, getting it doesn't involve driving to the nearest Apple Store or retailer. Let Macworld's Dan Frakes help you through the installation process, from the simple to the outrageously complex. It's easier than ever to install Lion, Apple's newest version of Mac OS X-you can purchase and download it directly from the Mac App Store and install it within the hour (assuming, of course, you've got a broadband Internet connection). But just because it's easy to get doesn't mean you should dive in head-first. There are things you should do beforehand, decisions to make along the way, and tasks to perform afterwards. If you'd like a little extra help, you might be interested in Macworld's Lion Installation Superguide, an in-depth instruction manual for the process.
