CCleaner is without a doubt the most famous application for Windows when it comes to system maintenance, and now we have it available for Mac OS X.
At the moment the application does not have a high level since they are in full development, but they hope little by little to get a complete application and be able to stand up to other successful apps like Onyx.
Of course, it keeps two things the same with respect to the Windows version: it is still free and the interface will be quite familiar to those of you who have used it.
