Have you considered booting your 10.13 system with a 10.

You might think why users want to install macOS Sierra when they can install macOS High Sierra, macOS Mojave. If it's a R/W image or (not sure) sparse disk image it will copy everything from the first to last bytes on your drive, thus the full disk size's file size. For installing this, you need its DMG file. Then you can take your drive you want to restore too and use Disk Utility to restore the disk0s2 boot volume and cp -F your entire EFI's zipped contents over to the "plain Clover" EFI partition you made earlier. I have noticed when preforming full disk backups using Disk utility on (10.12 w/ HFS) I can get a good image of the boot drive nicely compressed with all partition schemes/drive IDs, etc in tact as long as the disk you want to image isn't mounted and you select the option for a compressed DMG, I never do the full container, just backup your EFI partition into a ZIP file, save it with your boot disk DMG, and recreate the EFI+disk0s2 layout with a Multibeast and just install the plain version of Clover while EFI is mounted. Yes I know that there is carbon copy cloner and super duper to do the job but would like to use onboard methods as the way using Disk Utility was always reliable. Which one of these images is the right one? I assume the bigger one but I dont get why they are that much different in size considering the „Root“ device should contain the lower containerpartition anyway.
I did that and endend up with an image of 250gb (thats the size of my entire ssd). Somewhere else I read that you have to create an image of the apfs container (one level below the „root device“).
Then I highlighted the „Main“ ssd/Root device and created a dmg. I tried to do so by checking the list view option at the top left corner of Disk Utility and deactivated the high Sierra volume (lowest one in tree size view). Before going to download MacOS High Sierra dmg file make sure where you want to install the MacOS High Sierra Operating system because if you are Mac user and you are curious to download and install MacOS High Sierra on Mac computer, Needless to say, you need to download MacOS High Sierra from App Store. If you have a Mac computer, you may also grab it from the App Store easily. Downgrading from a later OS is still possible with Mac operating systems. How can I do this with High Sierra and its apfs file system? If you wish to downgrade from a later operating system to that of macOS High Sierra, you should still get the macOS High Sierra download DMG file.
