Mac OS X is the operating system of the Apple Macintosh. One of the features that make this computer the preferred choice for many users is the built in tool called the "CCleaner". This software can delete files and other problems in the hard drive of the computer. There are many reasons why it is important to have a good tool to clean up a computer and keep it running smoothly. In a way, we are lucky to have such a tool to clean up our computers and keep them running well. In most cases, all you have to do is visit the website that offers the application and download it onto your hard drive. It is important to remember that the site you will download the application from should be approved by Apple. If it is not, it will not do you any good. However, the website itself should offer the download for free. The application should also have an option to allow you to run it on the default settings, so that it can scan your computer at startup and clear up problems. If you don't have the application installed yet, it is best to download it before you make any changes to your computer. You can find the link on the website to download the application. Once you have the application on your computer, you will be able to run it with just a few clicks. After it finishes scanning, it will provide you with a report to read to see what it has found on your computer. You can then choose what needs to be cleaned up. It will then search through your hard drive for those problems and delete them. So whether you use it to clean up your computer or you use it to remove unwanted files from your hard drive, the CCleaner software is a valuable tool.
