Mac Cleanup Pro is not Apple. No Anti-Virus software or so-called “cleaning” apps are needed or recommended for Mac OS. They can conflict with Mac's own built-in security. At best they will slow your Mac by using unnecessary resources and at worst will bork your entire system.

I don’t clean my Mac other than an occasional run of MalWareBytes. I have Sierra set to automatically empty my trash now. I’m also cautious with which apps I install, and when I need to remove a program, I use AppCleaner to remove all traces including preferences and temp files. I agree; most 3rd party cleaning (& other utility) apps are no good. I am also leary of Onyx apps - they are NOT for the faint of heart. You could really mess up something unaware. I have used TinkerTool System (along with the free TinkerTool) for several years and I have never had an issue with it. No matter the OS, CCleaner is best everywhere when it came to cleaning.
