Latest Mac Catalina Update

Latest Mac Catalina Update

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

Get connected

It takes time to download and install macOS, so make sure that you have a reliable Internet connection. If you're using a Mac notebook computer, plug it into AC power.

Download macOS Big Sur

If you're using macOS Mojave or later, get macOS Big Sur via Software Update: Choose Apple menu  > System Preferences, then click Software Update.

Or use this link to open the macOS Big Sur page on the App Store: Get macOS Big Sur. Then click the Get button or iCloud download icon.

Begin installation

After downloading, the installer opens automatically.

Click Continue and follow the onscreen instructions. You might find it easiest to begin installation in the evening so that it can complete overnight, if needed.

If the installer asks for permission to install a helper tool, enter the administrator name and password that you use to log in to your Mac, then click Add Helper.

Allow installation to complete

Please allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart, show a progress bar, or show a blank screen several times as it installs both macOS and related updates to your Mac firmware.

Stay up to date

After installing macOS Big Sur, you will be notified when updates to macOS Big Sur are available. You can also use Software Update to check for updates: Choose Apple menu  > System Preferences, then click Software Update.

Or get macOS Big Sur automatically

If you're using OS X El Capitan v10.11.5 or later and your App Store preferences or Software Update preferences are set to download new updates when available, macOS Big Sur will download conveniently in the background, making it even easier to upgrade. A notification will inform you when macOS Big Sur is ready to be installed. Click Install to get started, or dismiss the notification to install later. When you're ready to install, just open the file named Install macOS Big Sur from your Applications folder.
