Can a disk utility change the size of an APFS image?
But if you create a disk image in APFS format, Disk Utility has a problem: it can’t change its size. Trying to do so simply returns an error. And I believe that this has been the case since the first full release of APFS in macOS High Sierra eighteen months ago. This is easily demonstrated.
How to create a new image in APFS?
Use Disk Utility’s File/New/Blank Image… menu command to create a new disk image, setting its format to APFS, and its size to something reasonable like 100 MB. You can make its image format anything you like, including a standard read/write disk image or either of the sparse options.
Why does APFS DMG not mount in safe mode?
A new discovery from a reader (thank you, Colby!) is that APFS DMGs won’t mount if you’re booted in macOS booted in Safe Mode. (Who knew!?!) If you’re not sure if you’re in safe mode, select the Apple menu > About This Mac > System Report button, then select the “Software” heading from the left column.
How to create an encrypted APFS volume from diskutil?

Is there a way to resize the APFs container?
APFS is only able to resize itself to space on the disk that exists beyond the last sector of the existing APFS container. If you have deleted a partition that was placed before the beginning of the APFS container, it won’t be accessible to resizing your existing APFS container.

How can I reclaim space from my APFS?
Shrinking Your APFS Partition to Reclaim Space If you decide you want to reclaim that space into your APFS container, you can do that using diskutil as well. First, though, you have to delete the JHFS+ or other partition and set it as free space on your hard drive. This command will do the trick, assuming your volume is named disk0s3.
