![]() I've used every single tool mentioned in this thread, including the dd method, and for once I can happily report that they all work. I'm guessing the writers just thought they would throw simple cloning in there because it was easy. Phoenix's primary job is not to be a cloning tool, it's really making an emergency boot drive by extracting the core OS from a working volume. When comparing SuperDuper vs CarbonCopy Cloner, the Slant community recommends SuperDuper for most people. Speculation on my part but I suspect it's true. I would suspect all the "cloning" tools are really sophisticated "script runners," meaning what they're doing could probably all be done in a script and the writers are probably exec'ing calls to the command line tools and letting them do their thing. ditto's command line usage takes some getting used to. asr (stands for Apple System Restore) used to be flexible but Apple made it inflexible since about Leopard. CCC may also make command line calls to asr when it does block by block cloning.

However, this is problematic when cloning boot disks like the one produced by Ben Sova's Patched-Sur, which depend on the EFI partition for critical functionality.

EFI booting in order to maintain compatibility with running non-Apple operating system on their hardware, they do NOT need the EFI partition in order to boot acOS.
