Treatment without side effects

In using PCs and Macs for nearly three decades I have found very few third party utilities that are worth installing. Typically they create new problems by using excessive RAM or conflicting with the operating system. Disk Doctor provides non-invasive treatment for your Mac without side effects like bloating or drowsiness. I sympathize with my friends who spend considerable money on a PC and then are dismayed to find that it has slowed to a crawl and become unreliable after a year or two. So often the problem is poorly designed applications or add-ins that never completely uninstall, conflict with the OS or bad housekeeping (e.g., not releasing RAM when unneeded). Apple products are, of course, in a completely different league. But they will suffer some operating degradation over time and periodically running Disk Doctor has kept my iMac and MacBook Pro operating efficiently for longer. It won’t correct the problem of new OS versions adding unwanted features that overburden older machines, but it should help maximize their life expectancy— at least that’s been my experience.
