This forum appears to be a mix of those running supported and unsupported Macs. Here, I'm running Ventura via OCLP. Hence my question re. the EFI Partition not being copied by CCC. The EFI is essential to booting via Legacy Bootable in unsupported versions. Since you didn't mention anything about OCLP, or the EFI, is that because you are running supported versions? If so I mistakenly assumed you were running OCLP. If not, then back to square one.

I think you should create a separate thread for this.Problem copying Ventura OCLP Legacy Bootable Copy Assistant to empty disk.
Successfully created this volume on an external drive - shows as startup disk and starts up properly. But have not been able to make a bootable copy at an empty external volume using CCC Restore, selecting the Legacy Bootable volume as source. Since CCC doesn't copy over the EFI partition, have manually copied the contents of the original EFI * + have also tried using Build and Install to Disk from within the copied volume by selecting the proper parent disk of the external (what I did originally to make the successful Legacy Bootable volume bootable - on inspection the EFI on the copy appears to be identical to the orignal ).
But either way nothing I've tried works. The new volume created by CCC Restore never shows up as a startup option, nor does it show up using the EFI boot option on a restart. Did this as a test, and it seems pointless to have a working Legacy Bootable volume if it can't be bootable when copied to an empty volume, or to replace a corrupted Ventura OCLP install if some unfortunate event occurs.
Perhaps someone can explain what I might be doing wrong, or offer the proper steps to make this work.
*Did this by way of EFI Agent, which is able to mount and open the appropriate EFI.

Obviously, you re doing something wrong. I make full clones, boot from them and then clone it again to the original drive almost every two or three weeks, montns ago, in OCLP macs. Look for my post among this thread. There is no problem at all.Re. Legacy Bootable Copy Assistant (Ventura OCLP)
Successfully created this as a backup on an external drive - shows as startup disk and starts up properly. But have not been able to use this to make a bootable copy at an empty volume using CCC Restore, selecting the Legacy Bootable volume as source, empty disk as destination. Since CCC doesn't copy over the EFI partition, have manually copied the contents of the original EFI * at the destination, plus have also tried using Build and Install to Disk from within the copied volume by selecting the proper parent disk of the external (what I did originally to make the successful Legacy Bootable volume bootable - on inspection the EFI on the copy appears to be identical to the orignal ).

Absolutely agree. Must be doing something wrong. It's not the EFI, since it's there where it belongs. When I do a CCC clone (either by way of a standard clone or a restore - have tried both ways) of the Legacy Bootable backup, I'm noticing in DU that only the Data volume is copied, while DU shows both Data and System for the Legacy Bootable volume. Since apparently the default behavior of CCC is to only copy the Data volume, this would appear to be normal, no?
The reason that was suggested was that the CCC developer can't support or address issues with non-supported Mac hardware utilizing OCLP. I asked him twice about that.
Tell me something: when you clone, do you delete completely the destination drive previous to clone it with Disk Utility?
EDITED: After a conversation with CCC support, recommended procedure:
Erase completely with Disk Utility before. The full drive. Sometimes when the destination drive have APFS partitions, CCC mess with them.
Erasing the full drive could be tricky. Besides Ventura OCLP, I have Catalina and High Sierra (HFS+) on partitions there. Don't want to lose all that.
Fully erasing the destination drive would mean erasing both the Ventura Data and System volumes, not just the Data. Is that what you mean?
Thanks, hoping that no misfortune arrives making it necessary to use the Legacy Bootable backup - if it happens, most likely needed at an update - will definitely pay attention to that.
…and I still think so.
Of course ¡¡¡iit´s a clone!!! Don´t look further, this is reason it´s not working. Don´t you have another drive, a drive you can erase?. Even a usb flash drive can do, just for testing.
