I'm trying to automate creating an encrypted APFS image with files in it. What I have so far:
>>> hdiutil create -megabytes 1 -layout GPTSPUD -fs apfs -volname encryption encryption.dmg created: .../encryption.dmg >>> hdiutil attach -stdinpass encryption.dmg /dev/disk2 GUID_partition_scheme /dev/disk2s1 Apple_APFS /dev/disk3 EF57347C-0000-11AA-AA11-0030654 /dev/disk3s1 41504653-0000-11AA-AA11-0030654 /Volumes/encryption >>> diskutil apfs deleteVolume disk3s1 Started APFS operation Deleting APFS Volume from its APFS Container Unmounting disk3s1 Deleting Volume Finished APFS operation >>> diskutil apfs addVolume disk3 APFS encryption -nomount -stdinpassphrase Exporting new encrypted APFS Volume "encryption" from APFS Container Reference disk3 Started APFS operation on disk3 Preparing to add APFS Volume to APFS Container disk3 Creating APFS Volume Created new APFS Volume disk3s1 Disk from APFS operation: disk3s1 Finished APFS operation on disk3 >>> hdiutil detach -quiet /dev/disk3 >>> hdiutil detach -quiet /dev/disk2 >>> hdiutil attach -stdinpass encryption.dmg hdiutil: attach failed - no mountable file systems
But the final attach command failed.
If I try to open the resulting DMG in Finder, it too tells me that there are no mountable file systems, so clearly I failed to add the volume, even though the
addVolume command succeeded and said it successfully created the volume.
Maybe it didn't though, so does anyone know how to do this?
