In the advertisement, the box is not checked that says "cleans Everywhere" for the free version.
So what does free version clean? What does Pro Clean? Is there a free vs pro page for mac
specific to the question I have asked?
"Clean Everywhere" simply means that the Pro version can clean all user accounts on the computer when used by an admin user.
The Free version only cleans the user account that it is installed on.
The Mac version comparison of free vs pro is at the bottom of this page: https://www.ccleaner.com/ccleaner-mac
