Q: I want to find a good Mac cleaner

There are none and the ones that say they "clean" frequently cause more problems than they say they will fix.

Just what makes you think you need a "cleaner"?

There are none. What's to clean?

Avoid all products claiming to "clean" a Mac. It is a marketing term used to exploit unsophisticated computer users, and devoid of any applicable meaning.

If you're experiencing trouble with your Mac, describe the symptoms.

Excerpted from Effective defenses against malware and other threats:

• Never install any product that claims to "clean up", "speed up", "optimize", "boost" or "accelerate" your Mac; to "wash" it, "tune" it, or to make it "shiny". Those claims are absurd.
  • Such products are very aggressively marketed. They are all scams.
  • They generally operate on the flawed premise that a Mac accumulates "junk" that needs to be routinely "cleaned out" for optimum performance.
  • Trial versions of those programs are successful because they provide the instant gratification of greater free disk space.
  • That increased space is the result of irreversible destruction of files, programs, or operating system components normally protected from inadvertent alteration or deletion. The eventual result will be unreliable operation, poor performance and random crashes that may not become evident for months or even years after their use, when updates to programs or OS X are eventually released.
  • Memory "cleaners" that circumvent OS X's memory management algorithms work by purging inactive memory contents to mass storage, which can only result in degraded performance and accelerated hardware failure.
