How create dynamic (growable) DMG file using terminal in MacOS

Question

I want to create dynamic (growable) dmg file. I know sparse bundle works well with dynamic file but i want to create blank dynamic dmg file. I tried the following but did not work. Can anyone help please!:

Answer 1

Create a Sparse Image (.sparseimage) rather than a Sparse Bundle (.sparsebundle).

$ hdiutil create -size <size> -type SPARSE -fs HFS+ <name>

So to create MyDMG.sparseimage that would hold a maximum of 100 MB you would do:

$ hdiutil create -size 100m -type SPARSE -fs HFS+ MyDMG
