I'd say in the last decade or so I only ever needed to 'clean' my Mac once, and that was when I was running old software which had generated a 2 GB text file of error logs before I noticed it. If you're getting down on drive space where a GB or two of caches is mattering then you have more serious drive space issues and need to instead consider offloading files to external storage. Sure, caches take up room, but they also speed up your computer booting and programs loading. Also many of these tools mistakenly clean things which should not be cleaned (kind of like inviting your mother to clean your room). Furthermore, CleanMyMac is well documented on these forums (I was just helping somebody with a 'slow Mac' issue 5 minutes ago) as slowing down a computer because it is constantly using resources. Cleaning up a dozen obsolete preferences files from 2005 isn't going to do anything. But we know what is taking up space, the thousands of photos and videos. The only valid reason that article itself admits is freeing up space. The developers are happy to sell them to people who have switched from PCs and are used to buying those tools. Mac cleaning tools in this day and ageare solutions in search of a problem (if you read the article the blogger kind of says that). a couple of dozen people who have been helping others for decades on this forum. I've never heard of that site before and you have one self-proclaimed expert vs.
