I think it does! So, APFS sounds similar to HFS, then - i.e. I tried to use the recovery of the source system first, but in this case the unmount command failed (IIRC the dd command refused to work).

In addition I'd like to add a comment regarding the startup process in recovery: It's best to use the recovery of an independent system like a DVD or an install media. Perhaps you could change the tutorial and the command line to adjust the target container size accordingly?ДЄnyway, everything else worked as expected, thanks for the tutorial! I would only suggest changing the dd command line in your tutorial to the syntax suggested from Adrian (with rdisk and 1M it took only 3 minutes instead of 47 minutes on my system with your syntax).

Because I had no ideas how to change partition types in macOS I decided that it's best to format the target disk with an empty APFS container before copying the source container with dd. I had the same thoughts, that it would not matter which type the target partition has, but after copying with dd the target partition was not recognized as an APFS container. However I do not know of a utility which does this. In principle it should be possible to modify the container's keybag, and to rewrap the container's keybag and the volume's keybag, to suit new UUIDs.

Note the cloning procedure works with software encryption but I expect it would not work with hardware encryption. The only way to do that would be to disconnect the internal drive. So I have not been able to prove that the clone is bootable. I had the clone on an external drive and my computer always chose the internal drive. It is not possible to choose whether the original or the clone will boot the computer, because the UUIDs are the same.

I have successfully mounted and unlocked the cloned volume. I wonder whether the purpose of apfs.util -s is to produce an immediate secure erase. The volume UUID is used in the decryption, therefore it must be preserved. The procedure you describe also works with encrypted volumes if you do not change the volume UUID. The only situation where the media speed does not apply is when you are copying between partitions on the same HDD because there will be a lot of head-seeking activity. Then the copy will go at 150MB/s reading and 150MB/s writing and 40GB will take between 4 and 5 minutes. In your example, suppose that the speed of the 128GB SSD in the MacBook Air is 300MB/s. The copying will then go at the speed of the media. Sudo dd bs=1m if=/dev/rdisk0s2 of=/dev/rdisk0s5 Read from the physical partition, disk0s2 in your example, instead of the synthesized disk, disk1. You can make dd copy much more quickly by doing three things. More programs may request re-activation (re-registration).If you're using Finder Alias files, these may not work any more afterwards (that's because they rely on each file's unique ID, and those IDs change when copying files over to the destination).The alternative would be to perform a file-by-file copy, as it's done by 3rd party tools like Carbon Copy Cloner.ДЄ clone operation by copying individual files has several disadvantages over aВ sectorВ copy: It performs a sector-by-sectorВ copy (while skipping unusedВ sectorВ .

About cloning (copying) entire Mac volumes Usually, when you want to clone a Mac volume, you'd use Disk Utility's Restore operation. TL DR If Disk Utility fails to clone an APFS container, giving 'APFS inverter failed' as error message, a work-around solution is to copy the partition with the 'dd' command into a same-sized partition, then fix the cloned container's UUIDs.
