The program will quickly scan your computer and identify all of the 'garbage' files on it. It will ask you if you want to delete them and allow you to free up a lot of space on your hard drive by doing so.
CleanMyMac also allows you to completely uninstall any program on your computer or to delete files that no longer work, leaving your computer like new.
CleanMyMac is a very full-featured tool with a clean, intuitive interface that allows you to keep your computer running well for a longer period of time.
The trial version only allows you to delete 500MG of unwanted files.
