It's very quick and easy to use as well which has made it a very popular utility that can even be used by people who are completely new to Mac systems. When you download this utility, simply perform a scan like you would in your usual anti-virus applications. After the scan is complete, you get a list of junk items on your computer that can be easily wiped off. The list includes junk files, residual files and even very large files that are clogging up space on your system. The UI is very clean. There is just a simple window that comes with a system memory dump gauge. Below it, you see a small list displaying different categories which contain memory that can be freed up with cleaning. You can just hit the button and clean all these junk files from your computer within seconds. Whenever you feel like your computer is slowing down, just scan it and remove all unwanted files within a split of a second.
