Messages in the disk cloning window instruct you or indicate the current state of the program. Below are given explanations of them.
Select source and destination
– Suggests you select the source and destination disks.
Clone will not be bootable (Source is not bootable)
– The disk clone will not be bootable because the original disk was not bootable.
Clone will not be bootable (Destination is not bootable)
– The disk clone will not be bootable because the file system or partitioning of the destination disk does not comply with the requirements.
Clone may be bootable
– More likely the disk clone will be bootable.
Destination has insufficient space
– The volume of the destination disk must be equal to or greater than the volume of the source disk.
Source and destination must differ
– The same disk cannot be selected as the source and destination at the same time. Choose another disk for either the source or destination.
Destination is read only
– The selected destination disk has hardware or software write protection. Deactivate the protection or select other disk.
Source or destination is not accessible
– The program cannot access a previously selected disk. If you use an external or network disk, make sure that it is connected. To verify that a disk is accessible, try to preview its contents in Finder.
Mac OS Extended or APFS required for source and destination
– The file system of the source or destination disk does not comply with the requirements.
Mac OS Extended (Case-sensitive, Journaled) recommended for destination
– Since the source disk has case-sensitive format, it is recommended that you format the destination disk with the "case-sensitive" option.
Clone will not be bootable (unable to create bootable volume on the destination)
– The destination volume is APFS formatted while the source has Mac OS Extended formatting. To make the destination volume bootable, it's formatting should be also Mac OS Extended.
