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.
