Sequoia 15.2 and Carbon copy cloner

Shirt Pocket (Super Duper!) today posted this warning, that macOS 15.2 breaks system copying.


So, may I ask: has anyone both updated to 15.2 AND successfully run Carbon Copy Cloner, please: or does CCC also fail?


TIA…!

iMac Pro, macOS 15.1

I believe the CCC warning is related to the Legacy Bootable feature. The normal backup works fine in Sequoia.


CCC's legacy works fine with Intel Macs but not with Silicon Macs.  The following is what Rob of Bombich Software told me as a way to clone my internal boot drive on a Silicon Mac to an external SSD:


1 - Boot into Recovery Mode

2 - Erase the external disk in Disk Utility

3 - Install macOS on the external disk

4 - When the installation has completed, accept the offer to migrate data from your original source disk


It worked like a charm and I use it to run beta Sequoia updates.    


Until Apple fixes the replicator in Sequoia We'll have to clone as above.

Kurt, you are far too kind with your time. Thanks so much! In the spirit of sharing workflow (Neurosis) There are new apps that often drive my "need" to reformat. My latest trysts were with Steer Mouse, Marta, Eagle cool, Found, Luminar and Dupe Guru, also Adobe Bridge. Even when there aren't any new apps in my workflow, I find the need to "clean" often - remnants from the Final Cut Pro days I guess. I also travel a lot in places like Africa. Knowing that I have a "one-click"thumb drive in the event of a problem is comforting to me as internet is quite spotty in developing nations - I can't just quickly reinstall software.


At any rate, I'm grateful to you for the post. I'll update my CCC. Cheers
