CCleaner is a system optimization, privacy and cleaning tool. It removes unused files from your system – allowing your Mac to run faster and freeing up valuable hard disk space. It also cleans traces of your online activities such as your Internet history.
CCleaner comes with a user-oriented interface that helps you view basic information about your Mac, such as the running macOS, computer model, processor and RAM info. The side panel offers you access to the built-in Cleaner, Tools and Options tab.
With the help of the built-in Cleaner tool, you can delete Safari’s Internet history and cache along with your download history and all stored cookies. In addition, you can empty the System Trash, Logs and other temporary files.
On top of that, you can also clear the Internet cache, history, cookies, download history, site preferences and more from other installed Internet browsers.
