What is CCleaner for Mac?
CCleaner for Mac is a small, effective utility for computers running Mac OS X that cleans out the 'junk' that accumulates over time: temporary files, broken system permissions, and other problems.
CCleaner protects your privacy. It cleans your browsing history and temporary Internet files, allowing you to be a more confident Internet user and less susceptible to identity theft.
CCleaner can clean unneeded files from various programs saving you hard disk space, repair permissions, help you uninstall software and stop certain background programs from starting with OS X.
