This is not a review per se, it is a discussion of the class of softwareto which this program belongs. As a public service to the MacUpdatecommunity, I've found as many of these 'cleaner' apps on this website asI could and listed them them below. (I did a search for 'cleaner'.) IfMacUpdate will let me, I intend to post this every time a new or updatedversion of one of these things shows up on this site. There are 39 inthe list, and it seems like new entries in the 'Mac cleaner' marketspace pop up every day, metastasizing like a cancer. Unfortunately, moreis not better. They are all of dubious value. Many have no reviews atall. Many have what look to be essentially fake 5-star reviews with nouseful commentary. Many -- probably the most accurate and honest -- havenegative reviews, by users who have been burned by them. Most of thedevelopers' descriptions boast about what a great job they do, but thetruth is, there are no good, comprehensive, head-to-head reviews ofthese programs by impartial 3rd parties. True experts in macOSmaintenance advise against using any of them, because in general theyserve little useful purpose and they can easily do more harm than good.Macs simply do not need 'cleaning.' (See for example:https://www.thesafemac.com/the-myth-of-the-dirty-mac/) Some of theseprograms are notorious for being little more than malware. The user iswell-advised to read any program documentation and make a RELIABLEBACKUP before attempting any changes. If I have missed any programs thatshould be on the list, please leave a comment and let me know. I willrate all these programs with one star, probably one more than theydeserve. And I would appreciate comments. If you disagree, please speakup. But if all you can come up with is 5 stars and a sentence or twosaying that program X is great and I don't know what I'm talking about,please save your breath. No one here will take you seriously. And Iapologize for the almost unreadable formatting, a severe limitation ofMacUpdate itself, which compresses maximum text into minimum space,leaving no whitespace for readability. :: BEGIN LIST: : Aooro : AppCleaner & Uninstaller : AutoTrash : AweCleaner : CleanGeeker : Clean Me: Cleaner One Pro : CleanMyMac X : Combo Cleaner : Disk Aid : DiskCleaner : Disk Cleaner Pro : Disk Expert : Disk Health : DiskKeeper Advanced Cleaner :DiskKeeper Cleaner - Modern : DiskKeeper Pro : Disk Xray : Doctor DiskCleaner : HD Cleaner : iMac Cleaner : MacBooster : Mac Cleaner :MacClean : MacClean360 : MacCleaner Pro : MacCleanse : MacEnizer : MacMaster :Mojave Cleaner : PowerMyMac : Pro Disk Cleaner : Quick Cleaner : Sensei: Stellar SpeedUpMac : TrashMe 3 : Washing Machine : WeCleanse : WiseMac Care :: END LIST : :: The only system maintenance tools I recommendare 1) TinkerTool System, a true bargain priced at only $14 for a singlelicense. TinkerTool System is a an exceptional piece of qualityengineering, safe when used properly, and superbly documented, within-depth tutorials for every option. 2) OnyX, from TitaniumSoftware, another excellent developer. 3) I have used Northern Softworks' 'Cache Cleaners' in the past (the latest being 'Catalina Cache Cleaner,' which I have not used) and their products are first rate. As for the rest, listed above, it is safeto say that nobody who really knows what they're doing with Macs andmacOS will touch them. Don't get sucked in by a pretty interface. Youmay very well regret it. -SB
