CCleaner is a must-have tool if you want to keep your mac working at its best as it includes cleaning tools, start-up analysis, registry optimization, and an application uninstall assistant.
CCleaner includes a complete system analysis that can find its way to every corner of your computer in order to find all kinds of unnecessary files such as: temporary internet files, obsolete registry keys, badly done installations, cookies or other remnants of files on your browser, among many other things.
The cleaner can scan many different areas on your computer, including the recycle bin, temporary internet files and the clipboard, although its main benefit is that it supports many additional programs. All of them can accumulate trash files which can then be eliminated.
You can set it up once it is installed so that the CCleaner options in the recycling bin menu appear, even though many of the tools are found within the program itself, with a very easy-to-understand interface and relatively high speeds.

Great that this program, in my opinion not very useful :P, is now available for Mac. Anyway, I prefer to manually take care of slowing down my PC. Regards
