I just made a bootable external Thunderbolt 3 1TB drive with my m1 MacBook Air and Monterey beta. I used CCC to make a complete backup of my Monterey System Disc but the copied disk was NOT bootable. I then used the Mac OS Restore utility to load new install of the Monterey Beta to the CCC newly created copy and BINGO! I have a BOOTABLE thunderbolt 3 external drive. I have done 2 of these drives 1 BIG SUR and this MONTEREY. I'm no expert, but it has worked for me ...TWICE
Got a tip for us?

Now that the M1 iMac does not allow booting from a clone, is there any advantage of CCC?

Yes you boot multiple macOS versions on M1 on the internal drive. Thats why the startup disk option is available.
Not really because the bootloader on M1 is unlocked and you have the option to also disable SIP on M1 Macs.
A non-bootable backup still gives access to user data. Backups are never irrelevant. I'd love to make a backup of my life and go to the outer space non-corded.
So I have a Question ... I have created and booted from a 1TB thunderbolt 3 external boot for Mac OS 12.0 BETA on my M1 MBA.
It shows up in System Preferences as bootable. It also shows up when I hold down the "ON" button until system restore options show up and is listed beside the system HD as a bootable option.
Are you telling me that it is still use the system HD to be able to see and choose the external drive to boot from, and that if the internal HD is damaged, it will not boot from the external drive.
I have erased the internal HD and the external shows up and boots the system. Is it that I have NOT erased a hidden partition that provides access to the external ... or what the heck is going on with all this, "... it can't be done ..."
Now, I have only used thunderbolt externals, could it be that it won't work with USB external drives?
I'd like to know if I actually accomplished something, or am I just fooling myself?

Carbon Copy Cloner 5.1.27 and CCC 6.0.x should make bootable clones of M1 Macs again.

i am running 6.0.2 and i can not create a bootable clone. I have been a CCC user since 3.0Carbon Copy Cloner 5.1.27 and CCC 6.0.x should make bootable clones of M1 Macs again.

Did you try Legacy Bootable Backup Assistant... Sorry, I can't test as I don't have a M1, yet.
It seems that Apple is going to help fixing the loss of cloning a bootable backup. As it's not easy anymore to swap a component like a SSD, because it's soldered and the T2 security enclave prevents it, it's more important than ever to get back that functionality. We need boot functionality from an external volume and hopefully a better user experience of cloning the internal media, instead of another technical barrier. I hope that there will be no close future, when we jailbreak our Mac…
I was able to create a bootable clone with CCC 6.0.2 after selecting Legacy Bootable Backup Assistant. It doesn't show up as a selection in sys prefs>startup disk, but it's there to select with an Option Boot. I'm running a 27" 2017 Intel iMac.
Same here. Made a bootable clone from an iMac 24" M1 with SuperDuper!. Follow the procedures as stated in the blogpost of Wednesday, May 05, 2021.
There's one very important point though, not mentioned on the site: Neither your internal disk, nor your external disk should have a name that ends on a number (according to the support of Dave Nanian). Which was exactly the reason my disk failed to clone...
After changing the name of my internal disk the backup went well. And was I able to boot from the external disk by following the procedure on the mentioned blogpost.

A FYI CCC 6.03 came out Sept 14th, and the latest 6.0.4-b1 is for qualifying the product for Monterey. Big Sur is not a issue for bootable M1 backups, while Monterey betas seem to vary the success of how the APFS replication utility works for making a bootable clone. I had success, and not, sometimes Monterey has admin authentication changes to installation of Monterey updates as well as booting a external volume. So more fun, if you know what I mean.
