Latest Mac Catalina Update

by



If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps that are installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar, and Photos.

This is not a review per se, it is a discussion of the class of software to which this program belongs. 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. Before you even *think* of installing any of them, PLEASE read this: https://discussions.apple.com/docs/DOC-8841. There are now 74 (that's SEVENTY FOUR) programs in the list, and it seems like new entries in the 'Mac cleaner' market space pop up every day, metastasizing like a cancer. Unfortunately, more is not better. They are all of dubious value. Many have no reviews here. Many have what look to be essentially fake 5-star reviews with no useful commentary. Many -- probably the most accurate and honest -- have negative reviews, by users who have been burned by them. Most of the developers' 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. 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. Macs simply do not need 'cleaning.' (See for example: https://www.thesafemac.com/the-myth-of-the-dirty-mac/) Some of these programs are notorious for being little more than malware. Many have 'disk' in their name, although disks, especially internal ones, are now a thing of the past. (Although macOS still comes with the storage drive initialized as 'Macintosh HD,' a quaint relic of a bygone era.) You are well-advised to read any program documentation and make a RELIABLE BACKUP before attempting any changes. If I have missed any programs that should be on the list, please leave a comment and let me know. I will rate all these programs with one star, probably one more than they deserve. And I would appreciate comments. If you disagree, please speak up. 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. No one here will take you seriously. 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. :: BEGIN LIST:: Aooro : AppCleaner & Uninstaller : AutoTrash : Avast Cleanup : AweCleaner : Broom : BuhoCleaner : CCleaner : Clean Disk : CleanGeeker : CleanGenius : Clean Me : CleanMyDrive : CleanMyMac X : Cleaner One Pro : Cocktail : Combo Cleaner : Disk Aid : Disk Analyzer Pro : Disk BoostUp : Disk Clean Pro : Disk Cleaner : Disk Cleaner Pro : Disk Diet : Disk Doctor : Disk Expert : Disk Health : Disk Janitor : DiskKeeper Advanced Cleaner : DiskKeeper Cleaner - Modern : DiskKeeper Pro : Disk Manager: Disk Sensei : Disk Xray : Disk Xray Lite : Doctor Disk Cleaner : FastScanner Pro : Hard Disk Manager : HD Cleaner : iBooster : iCare : iMac Cleaner : MacBooster : Mac Cleaner : MacClean : MacClean360 : MacCleaner Pro : MacCleanse : MacEnizer : MacMaintenance : MacMaster : MacOptimizer : MacTuneUp : Mechanism8 : Mojave Cleaner : More Disk Space : Omni Remover : Power Booster : PowerMyMac : Precious Disk : Pro Disk Cleaner : Quick Cleaner : SubRosaSoft Drive Cleaner : Sensei : Startup Manager : Stellar SpeedUpMac : TrashMe 3 : Washing Machine : WeCleanse : WinZip Mac Optimizer : Wise Mac Care : Wise mCleaner : XustoDisk : Xustomite :: END LIST :: The only system maintenance tools I recommend are 1) TinkerTool System, a true bargain priced at only $14 for a single license. TTS is a an exceptional piece of quality engineering, safe when used properly, and superbly documented, with in-depth tutorials for every option. 2) OnyX, from Titanium Software, has a loyal following and gets good reviews here. 3) I have used Northern Softworks' 'Cache Cleaners' in the past (the latest being 'Big Sur Cache Cleaner,' which I have not used) and their products were always first rate. Still, the same warnings apply. 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. Don't get sucked in by a pretty interface. You may very well regret it. -SB

Check compatibility

macOS Big Sur is compatible with these computers:

Catalina update problems like Mac won't boot after macOS update still occur. Except for APFS conversion, the macOS Catalina update will automatically divide your hard drive into two volumes. One is the read-only Macintosh HD system volume, and the other is Macintosh HD - Data for saving your files. If the installer shows a list of apps that are not optimized for your Mac, learn about 32-bit app compatibility, then choose whether to proceed with the installation. For the strongest security and latest features, upgrade to macOS Big Sur. Avast Cleanup is an optimization tool that detects unnecessary items and performance issues on your Mac, optimizes disk space, and improves the speed of your system. Avast Cleanup Premium is a paid product that requires a subscription to use. I prefer how Catalina Notes looked. I never had issues with Catalina and I liked this Mac when I first got it before the update. I think eventually I will wipe this Mac clean to get Catalina or get rid of it and get a new M chip Mac as Big Sur runs snappy on that form my tests but also id get a separate windows system for certain software.
