One of the things I love about Macs are they they are low maintenance. You just have to do some basic clean-up to keep them running like you took it out of the box. There are a handful of apps -- some popular, some not -- that help you with taking care of such chores. One of them is Mackeeper.

The program is really easy to use and has a Mac-like interface. It cleans out the unnecessary data that your Mac might store and really does a good job in tidying up things like old binaries, cache, duplicate files, unnecessary stuff from language packages, data logs and old files.
