Whether you develop software, work at the help desk, or are simply assisting a friend or relative, creating a step-by-step tutorial can be a huge help--but corralling all those screenshots and notes can be a chore. Clarify aims to clean up the process, letting you easily create tutorials--complete with screenshots, instructions, and annotation. The software also includes tools to share your documents, although the limited options might present a few problems.

OS X Lion 10.7.2 recently added the ability to drag-and-drop files between desktop spaces, but it’s not particularly intuitive, and downright awkward for users with multiple displays. Thankfully, hardcore Mission Control fans now have a better option called Yoink.

Do you back up your Mac? If a disaster takes out your hardware, will one of those polite guys from an insurance commercial appear, honoring your policy with a snap? Since that’s pure pipe dream, you’ll need to provide proof that you owned that computer—and any other items in your claim. Home Inventory provides the framework for you to catalog everything, even helping you keep track of the value of your items versus the maximum coverage of your policy. The software misses a few important options, but its simple interface and invaluable iPhone helper app make the giant task of inventorying your home manageable.

News flash: Macs can develop problems, just like any computers. But they tend to run fine without antivirus software and the general vigilance that helps keep PCs trouble-free (some of ’em must run fine, right?). But that doesn’t mean your Mac wouldn’t benefit from some occasional maintenance. Enter MacKeeper, a suite of tools aimed at keeping your Mac healthy. That’s a bold claim, and trust is important when using any app, but it’s crucial when your system is on the line. Unfortunately MacKeeper, with its occasionally awkward English and warnings about the importance of scanning OS X for viruses, makes a shaky first impression (the overbearing emphasis—in and out of the app—on MacKeeper’s Facebook popularity doesn’t help). When it comes to maintaining our Macs, we want Don Draper. MacKeeper delivers Pete Campbell.
