Don't get sucked in by a pretty interface. As for the rest, listed above, it is safe to say that nobody who really knows what they're doing with Macs and macOS will touch them. 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. 2) OnyX, from Titanium Software, another excellent developer. TinkerTool System is a an exceptional piece of quality engineering, safe when used properly, and superbly documented, with in-depth tutorials for every option.

And I apologize for the almost unreadable formatting, a severe limitation of MacUpdate itself, which compresses maximum text into minimum space, leaving no whitespace for readability. But if all you can come up with is 5 stars and a sentence or two saying that program X is great and I don't know what I'm talking about, please save your breath. I will rate all these programs with one star, probably one more than they deserve. If I have missed any programs that should be on the list, please leave a comment and let me know. The user is well-advised to read any program documentation and make a RELIABLE BACKUP before attempting any changes. Macs simply do not need 'cleaning.' (See for example: ) Some of these programs are notorious for being little more than malware. True experts in macOS maintenance advise against using any of them, because in general they serve little useful purpose and they can easily do more harm than good. Most of theĭevelopers' descriptions boast about what a great job they do, but the truth is, there are no good, comprehensive, head-to-head reviews of these programs by impartial 3rd parties. Many - probably the most accurate and honest - have negative reviews, by users who have been burned by them. Many have what look to be essentially fake 5-star reviews with no useful commentary.

There are 42 in the list, and it seems like new entries in the 'Mac cleaner' market space pop up every day, metastasizing like a cancer. (I did a search for 'cleaner'.) If MacUpdate will let me, I intend to post this every time a new or updated version of one of these things shows up on this site. As a public service to the MacUpdate community, I've found as many of these 'cleaner' apps on this website as I could and listed them them below. Thanks again.This is not a review per se, it is a discussion of the class of software to which this program belongs. Well, you're getting mine within seconds. I'll never know which settings had been causing the problems, but using the DEFAULT command brought my iMac back to its brand new condition. I just saw a command that said something like 'Restore all defaults,' so I chose it thinking that it could do no harm. Even better, Onyx fixed the problems even though I had no idea of how to use it. They couldn't help me, either so, having nowhere else to go, I tried Onyx, and not only did those two problems disappear, but also another one that I had resigned myself to. I had had a couple of problems that they couldn't help me with, so I called Apple Care.

Anyway, I used Onyx WITHOUT THEIR PERMISSION, and it worked. I had assumed that Apple Support Communities would be against Onyx, because they are against everything that doesn't come from Apple, and they like to argue too much for my taste.
