Creating this thread since the MacOS 12 Monterey beta 2 was issued as a PB today.

The most up to date version of CCC is 6.0.2 released 6/30

You will now see this when running the Monterey Beta I am not sure of any changes that would really effect this version compared to how it was running with 11.5 beta 4. Haven't done any backups since Monterey being installed.

I have not been able to make bootable clones since Catalina. Not in 11.4 or 11.5. And now, not in 12.0?

You need to prepare the volume for APFS replication to work. 11.x and the new 12.0 creates both a system and data volumes. Erase both in the disk utility -> unmount backup target storage, erase system volume not the data volume, select erase volume group as preparation. In CCC you need to target that one volume as a destination in CCC with a new task. Then you will need to use the CCC choices in under your destination. click on the destination disk you will see this. Enter the legacy bootable backup assistant. I don't use SafetyNet for incremental backups, so that is off. Allow CCC to erase the volume. Now when you start CCC backup task it should tell you that you are Replicating the APFS filesystem data. After it gets done this in disk utility should show both a system volume and a data volume. Now see if it will allow you boot off of it.

So no you can't use CCC 6.0.2 to make a HDD bootable with 12.0b2 on a M1 Mac. Just use it with Migration Assistant in case something happens. Tested it under M1 Mac options, it just will boot a little then reboot again, third time it boots from the internal SSD asking if you want to report this failure.

I see PB4 Dude had a relevant observation that it might be possible to boot a external volume using Monterey but this latest beta 2 effected that.

i can’t get my 2020 iMac 27” to boot beta 2 from external SSD. Beta 1 did work. Guess I’m off the beta train for my iMac (external SSD works as expected with my 2017 MBP 15”) until at least beta 3.

If I remember correctly, this has been the usual pattern for Mike. After the 3rd or 4th beta is when Mike usually starts offering beta testing for the OS.

CCC 6: Beta testing on macOS 12.0 Monterey​

If you're beta-testing Apple's new macOS 12.0 Monterey, you can help us test CCC 6 against the new OS too. CCC 6.0.2 includes preliminary support for Monterey.

Please choose Ask a Question from CCC's Help menu to let us know if you encounter any problems or have questions about support for new features of that OS.
**There is nothing newer than CCC 6.0.2 at this time.

Delete the second data volume (under EDIT menu) so you have only one volume to start with with CCC. In CCC you need to target that one volume as a destination in CCC with a new task. Then you will need to use the CCC choices in under your destination.

click on the destination disk you will see this.

Hi R, I formatted the receiving Samsung T5 SSD as APFS and guid. The only one selectable in disk utility is T5 SSD, which I deleted with the minus sign. After I do that it doesn't show up in CCC as a destination. Would it be better to format as Extended Journaled since CCC is going to reformat it anyway?

You didn't need to delete the T5 SSD, that earlier statement was referring if a second external volume was showing in Disk Utility. The CCC Utility during the APFS replication performs a system/data volume recreation. Now what you need to do is just undo what you did by erase/format t5 SSD as a APFS volume. Then CCC should see it.

Right, I figured that out when it didn't show up in CCC. This then is the same process I think I used before with CCC that didn't work. Maybe it has something to do with this being 2019 27 iMac. If I go into Startup Security Utility using Command R on startup it only shows a firmware password option, nothing else.

CCC bootable clones are gone, developer says he was "stoked" at no longer having to supprt them. And then a PAID update to obsolete garageware

Well, I tried it again and it worked! Maybe I missed something on previous try with CCC. On restart, hit option and shocked to see it as an option. After booting into new volume when I go to Startup Disk in Preferences only the SSD is showing.

Thanks again R, now I can move on to fixing the split fusion drive.

No, Go back and read Posts #3 and #5 above.

Bootable backups of Big Sur are now explicitly deprecated on the Bombich website. CCC backup bootability is technically possible but this is not supported or stable and is therefore discouraged. And of course one cannot boot an M1 Mac from an external drive at all if the internal drive is damaged.

^^^^If one can not make bootable clones then CCC or SD are of absolutely no value. You can simply drag and drop whatever it is you want to copy (clone). And, if I could not boot from more than one drive on my Mac, or any computer, I would choose not to own such a machine.

while i hear you, i still live & die by CCC, which i use to backup my macs, in a way that works for me. so, 'of absolutely no value' seems a bit... over-the-top...

Read up about CCC. With a CCC clone of the data volume you can create a bootable clone of your drive by installing and migrating form the data volume clone. You can't do that by dragging and dropping.

^^^^Please re-read and understand my posts - again see posts #3 and #5 above. My Post #19 was responding to Post #18. I am aware that you can now make a clone of a boot drive with CCC. But, if that becomes impossible in the future, than as I posted CCC and SD will have absolutely No Value TO ME!

And, just as a side note - Prior to January 2001 (OSX Cheetah) it was possible to drag and drop to create a startup disk.

if? you're upset about something that may happen... or may not? and if it does, you can cross that bridge when you come to it (ie let us know how indignant you are... then). otherwise, why stress about an undefined future?

Well here i am with a

!

My good fortune as expressed in post #5 has evaporated? Repeated the steps outlined above, and for the life of me I can't get a bootable clone - either in Monterey, Beta 2 or Big Sur 11.5, RC.

The APFS replication can only occur if the drive volume you are copying to is erased to a APFS single volume. Then you need to allow CCC assistant to be able to erase that HDD or SDD. It doesn't work for M1 based Macs in Monterey yet (bootable).

^^^^Yep - I did that
