mac os could not create a preboot volume for apfs install

The Bootable Backup Assistant now creates a bootable sync task that has Aggressive Smart Scan enabled on the destination.

The Bootable Backup Assistant now makes sure that Preboot and Recovery volumes are dereferenced when deleting or erasing existing APFS volumes.

Note that duplicate volume names are allowed, just not in the same APFS container.

The Bootable Backup Assistant now enforces unique volume names when naming your destination volume (either after choosing to erase it or to create a sibling volume).The restriction is such that you cannot choose a name that already exists in your destination APFS container, unless you are erasing an existing volume and keeping the same name.

This will create an all new volume in the same container as the destination volume you selected.

When presented with formatting/erase options for that volume, you'll now have the option to create a sibling volume. To get this option, you must select an existing APFS volume as your destination.

The Bootable Backup Assistant now presents the option of creating a sibling APFS volume.

This utility activates when the user attempts to 'fix' the readiness warning.
