This software was Mac Keeper until recently but has had many negative opinions- presumably the reason for the new alias? "As you can see there are some strong feelings about any application that meddles with system files in the Mac OS. I agree completely that most "cleaning" applications for Mac OS are often worse than useless with the insidious and invasive Mac Keeper being case in point but at the end of the day it's up to the consumer to decide, it is our role to merely advise based on our pooled knowledge." Excerpt from http://www.mac-forums.com/ which recommends 'Onyx' FWIW, Mac Cleaner made such a mess of my Mac that it needed a new OS X install to get it working again. But that was 3 yrs ago, maybe it has improved? Whatever, the incessant popup got to me. PS- I do appreciate the need for advertising revenue but 'Son of Mac Cleaner' is not a good choice... I hope I have not mis-identified the product.
If you are looking for a good clean, I am using "CleanMyMac" for the past 2 years and it works great! https://macpaw.com/cleanmymac
Yes, seems OK- used it some time ago but my Mac runs fine; 'Click&Clean' is very good and simple, very fast & is my current favourite.
