Is this a bug ... or a ‘feature’?

I only say this partially tongue-in-cheek. This is another step—like forcing updates—that is part of Apple’s plan to lock down its OS and correlatively user settings as it marches toward ARM and a walled garden philosophy.

Every day Apple moves the ball closer and closer to the day when all Mac will run on a closed macOS system and only Apple approved store apps will run on their desktops and the complete elimination of 3rd party apps and access to the root level as we have accepted on iOS.

I think you mean “complete elimination of independent 3rd party apps.”

Apple needs the revenue stream from App Store app developers.

I did it with my cloud backup many times. I just backed it up to the cloud, all my apps, and settings. Who needs that useless Time machine that takes ages to backup useless files and configurations? And please remind me how many times your laptop is getting a logic board failure in a decade? so you want to keep using useless slow, old apps, that come with your OS just to backup your configurations so you can just load it up once in a decade? now calculate how many hours you lost waiting for that useless time machine backup vs. how much it would take you to install and set-up everything from scratch.
Who said Time Machine? CCC backup on a fast SSD is the way to go. I take my backup SSD along when I travel because not everywhere I can get a reliable internet connection and being able to boot from an external disk gives me the ability to test different versions of OS, Apps, settings you name it.

Also, having a bootable clone of a drive is not just for failures; it is a much faster and a better alternative to Migration Assistant.

I don't waste any time whatsoever for my CCC backups. It is scheduled to take place 3am every day while I sleep.
 
Just use Windows for one week and macOS will be perfect again. Believe me I’m an IT and half week I’m working for a big company with everything Microsoft related. HELL ON EARTH.

Not true at all, Windows 10 is just better, and it works better than macOS Catalina on my MacBook Pro.
 
Can this be a way for Apple to prevent people from use MacOS and build Hackintoshes? I mean, they must suffer badly from that when they have their software used in non-Apple-computers.
 
Apologize for being OT but speaking of bugs: I'm having to rebuild my Mail inbox far too often. This has been affecting me on multiple Macs over the past decade. When is Apple finally going to address stability in Mail?
 
Wow what is going on with Apple’s software QC process these days? I have never sat out an entire MacOS release before. I thought 10.15.5 would finally be stable enough to get me to upgrade from Mojave. But apparently not. And iOS 13 still has bugs that have been present since the first beta (looking at you, Mail). Something is really broken over at Apple right now.
Yep its called leadership it trickles down from the top
 
So let me ask you… where is that backup hard drive of yours located? I thought so! No safety in having your backup drive next to your computer, you know if God forbids your house/office burns down or you get robbed.
So now you’re telling me you have a second backup drive (twice the price now!) and you’re taking it offsite. Good! That’sWhat everybody should be doing with physical backups.
Now how much time do you spend doing the two backups, taking the drive offsite and then realizing one of your drive has crashed - it happens more often than you think and want!
And then what if you’re not around your home/office, say traveling, your computer has crashed, you have it replaced or repaired and you need your data NOW!
Now think about cloud backup… it happens automatically, you’re not responsible for the backup and redundancy of that data and you can restore anywhere.
Trust me, your time spent, purchasing hard drives regularly and always worrying if you’ll be able to retrieve the data is not worth the aggravation.
$100 a year for 2TB iCloud storage is a bargain! (use discounted iTunes cards to get to $100 cost instead of $120).
All it takes for ANY Form of cloud solution to fail is having no internet access. Good bye to your “backup with multiple levels of redundancy”. Oh, you might want to argue “let’s move to another place where internet is available”. Not so much for desktops and offices.

iCloud is generally not considered a reliable and robust macOS backup solution for quite a few home users. I don’t know what would happen for professional users, but I’d argue iCloud is not for them either.

Besides that, the mindset of “handing over your entire data collection to some cloud backup providers so you don’t need to worry about how they manage it” is just bs and dangerous. Your data, your responsibility. It’s part of your assets, however much it worth aside. Also, anything uploaded to the cloud has the risk of being hacked or leaked to the public. Whether data owner gets targeted or not depends on how VIP that target is.

Stop blindly praise cloud based backup solutions. You will learn a hard lesson when your cloud backup is no longer accessible for some reason.
[automerge]1590794920[/automerge]
I would argue that cloud is going to become essential.
Sort of yes but still cannot replace local data backup solution entirely, even for home users.
He didn’t think customers should ever open their machines, etc.
This is an extremely dangerous (and I also call it narrow-minded) mindset and the ultimate reason why Apple never release any sort of enterprise level products of their own aside from maybe that $50k Mac Pro and $5k monitor plus $1k stand and $400 wheel kit. I guess Steve Jobs don’t understand enterprise users the same way everybody else does.

I hope that is subtle sarcasm - if not I will tell why. I run a company. At any moment there may some form of IT failure. If that failure is on a critical path it must be fixed pronto. Can you guarantee the cloud will be available at that moment (looking at you Adobe!)? I basically will not trust anybody I cannot fire.
I use clouds for many years. They are more reliable then any other hard drive or thumb drive you will ever have. Of course, if you use ****** clouds, then it's your problem for having low SLA.
[automerge]1590855730[/automerge]
You think something stored at a location or locations remote to you, on media you do not control, that explicitly disclaims a service guarantee, is a backup?
Yes. You can say the same thing on your local backup that:
1. Apple is controlling your backups
2. Your neighbors are controlling your backups (fire, thieves and other scenarios)
3. Should I continue with your logical flaws?
[automerge]1590855792[/automerge]
Um, maybe because some of us don't want to store our secure files on someone else's servers?
You already store your secure files on someone else's server. It's called iCloud/Gmail and many other services. Welcome.

There are so few people using hackintoshes that I’m sure apple doesn‘t make any technical decisions based on their fear of that small group of hobbyists.

Believe it or not, many business uses of macs do *not* store their secure files in iCloud, gmail, or any other cloud service. Not everyone is a home user.
 
It gets worse !!! 2012 Mac mini, since 10.15.5 it now refused to boot at all with a drive connected via the thunderbolt interface. Remove it and it works..
ffs Apple, how the hell have you broken this!

I don't waste any time whatsoever for my CCC backups. It is scheduled to take place 3am every day while I sleep.

It's not an either/or situation.

I use CCC to make regular encrypted clones I keep offsite in case of disaster. I just plug them in and walk away for a while. CCC even emails me when it's done :) Last month in anticipation of replacing the internal drive on my iMac, I made a bootable clone to the SSD I was about to install, ran the new drive off an external enclosure for a while to test it, and then finally installed it inside the iMac. Totally seamless from a data perspective. (Though not seamless from a glued-together display perspective, but that's another topic).

BUT: I also have Time Machine running for more frequent, incremental backups. It's saved me many a time I've accidentally edited the wrong file or something, and most recently I used it to migrate my user accounts, applications, everything from one laptop to a new one. The restore process worked beautifully.

They both have their uses and strengths. I know CCC can be set up like you have it, but it's definitely more work for installation and doesn't have that super simple file recovery interface. Time Machine is ideal for total non tech literate people: you literally plug it in and then don't think about it again.

It always blows me away when people like you tell other users that the stuff they use regularly is "outdated" or "useless". The fact is, you have no idea how other people work or what their needs are or what they spend their time doing.

To mention just ONE example: I bought a new MacBook Air to replace an old one. I made a full Time Machine backup of the old Mac. That took, generously, about 15 seconds which consisted of me plugging in the drive and then going to make dinner. When I got the new Mac, I plugged in that same backup drive, opened Migration Assistant and told it what I wanted moved over. Then I went and did something else for a couple hours.

And when I was done, the new Mac looked exactly like my old Mac. Same files, same user accounts, same applications installed, same Finder settings, same internet accounts configured.

Total time I spent working on the two computers? Well under five minutes.

Now, since you're calculating "hours lost" let's pretend I just set that all up from scratch. Open up the new computer, set up two new user accounts (personal & work) and now on each account set up every single setting and preference, downloading every application I use that isn't installed by default. A couple hours, easily. So, please, tell me again how I can use my time better, what software is "useless". Because I'm sure we're all just dying to hear. It's great you "use clouds for many years" but not everyone works the same way you do.

I was going to go for the (up?)grade to Cat in a few days after my success with the Mojave Security Update 2020-003 yesterday, but I just came across this thread. I am running SuperDuper! on an APFS external SSD and have read both Dave's blog, https://www.shirt-pocket.com/blog/ and Mike's blog, https://bombich.com/blog/2020/05/27...impacts-bootable-backups-weve-got-you-covered.

I understand that this is only affecting “start from scratch clones” and not smart updates. I changed my SuperDuper! clone drive to APFS from HFS+ a while ago, but I’m wondering with all the changes to Cat APFS, will SuperDuper! require a complete new clone and thus this new booting firmlinks issue affect me after I attempt a Smart Update after the Cat upgrade?

I emailed Dave this question and he promptly replied: "Smart Update should work fine. I can also provide you with a command-line that will reestablish the backup if you have an issue."

Has anyone here tried SuperDuper! after updating to 10.15.5? and more rarely, has anyone made the jump from Mojave to 10.15.5 and then tried SuperDuper! Smart Update?

This bug also affects Carbon Copy Cloner competitor SuperDuper by ShirtPocket Software in exactly the same way. If you don't already have a backup from 10.15.4 or earlier that you can smart-update with 10.15.5, you're hosed. Fortunately I've got the earlier backup because I finally updated to Catalina on 10.15.4 a few days before 10.15.bug -- I hope this isn't some kind of game by Apple because switching to Time Machine would commit me to using a lot more disk capacity for backup than CCC or SuperDuper.

I had a horrible update to 10.15.5 that forced me to erase both laptops, go back to 10.15.4 cold install, then re-update to 10.15.5. The SmartUpdate in SuperDuper worked fine through this episode. I think I'd have lost my mind if I had cold-erased the backup.

You don't need a bootable clone / backup to create a Hackintosh.
 
Carbon Copy Cloner 5.1.18 just came out.

Good news:
  • Addressed an issue that Apple introduced in 10.15.5 (FB7706647) that will prevent CCC from establishing an initial backup of a macOS Catalina system volume.
Bad News;
  • Starting in 10.15.5, CCC will no longer back up a macOS Catalina System volume to a disk image destination (i.e. a sparseimage or sparsebundle disk image file). We're making this change reluctantly, unfortunately we just can't get reliable results when using Apple's proprietary utility with disk images.

Looks like CCC for Catalina is dead for good. Next? Killing Time Machine? Why Apple really hates people backup their data?

Not dead for good, you can still back up to an external volume. It means, though, that if you have a single backup drive for several machines, it has to be APFS formatted and divided into partitions, which is at worst impossible and at best a PITA.

And now the fine folks at Bombich Software have in turn broken Apple's own Disk Utility app (revenge is an ugly thing): The latest version of CCC 5.1.18 breaks the "Show Only Volumes" view in Apple's Disk Utility. You used to be able to select different views in Disk Utility. Now only the “Show All Devices” view works. I have verified that it is indeed CCC that caused this. Immediately after installing it the ability to change views in Disk Utility quit working. And by the way, it permanently breaks that view option in Disk Utility. I tried fully uninstalling CCC and the issue remains even after the uninstall. 🤦‍♂️

Good catch. I have CCC 5.1.18 installed on a Mojave Mac and Disk Utility will only display "Show All Devices". I would have never have noticed because I use & prefer "Show All Devices" anyway.

Please report it to Bombich like I did. Hopefully they can fix what they broke.
 
Someone had a problem with the Magic Mouse with the update, losing the configuration of the buttons, for now the solution I found was just to shut down and restart the iMac, and not the mouse. Obs. I have two Magic Mouse and the problem was repeated in both.
 
Yes, I know!
I've been working as an ”IT guy” since more than 20 years and use Windows too. I'm not saying anything about things not being worse elsewhere. Still, I think things should work even better considering that that Apple is behind both the hardware and the software.

But sure, I know stuff is complicated when it comes to hardware and software – especially when it comes to the complexity of operating systems – but that doesn't mean quality control can't improve.
I still don't understand why people say it's hell when it comes to Windows and IT. As I said before I have been out of the IT field since 2009 in which I was doing IT onboard a naval ship with 260 people onboard in the middle of the ocean where we had crazy security setups and also keeping people from trying to circumvent protections we had in place to keep people off social media amongst, keeping a second intranet active for classified materials among other things and it really wasn't that hard to do and can only imagine it being easier in a corporate environment.
 
Has anyone here tried SuperDuper! after updating to 10.15.5?


Yes.

I cloned a MBP running 10.15.4 using SD, to a freshly erased USB HD partition. Clone perfectly, no errors. Booted to the USB clone, no issues (other than being slow, as expected on HD).

I then upgraded to 10.15.5, and repeated.

I erased the same USB HD partition without error or issue. Cloned with SD to the same partition again perfectly, no errors. Booting to the USB HD partition starts normally, but at about 40% of the progress bar, the machines shuts down.

Option booting and changing Startup Disk in Sys Pref both see the cloned partition as bootable. DU (booting back to internal 10.15.5) sees the cloned OS as expected, formated and volumes as expected, and finds no error when running First Aid.

But it still won't boot.
 
The Superduper! Blog on the subject is interesting.

Dave Nanian makes it clear that Apple want developers to use the ASR (Apple System Restore) method instead of their own.

CCC have already released 5.1.18 which uses ASR and creates bootable first clones to get around the new bug.

Interesting that Dave Nanian of CCC describes ASR as incredible buggy and user hostile but CCC is using it.

Also note that another workaround to non bootable clones is to use the clone as the source for a fresh install/migreate form clone with Setup Assistant.
