About CCleaner for Mac's Rules

When you start CCleaner for Mac, you'll see two tabs (OS X and Applications) in the main window, each with several check boxes. These check boxes control many aspects of your system that CCleaner will clean.

To tell CCleaner for Mac to clean a particular area of your system, select the check box.

The remainder of this section explains what the check boxes do.

Note: Depending on what programs you have installed on your Mac, certain sections and check boxes on the Applications tab may not be available.

To change CCleaner's other settings, see this section.
