You typically extract some data from the (unmounted) partition or file 
that holds the encrypted image and then run dmg2john on that, producing 
a "hash". You can also run dmg2john et. al. directly against the image 
file or partition. In this case you already have an image file so you 
should just run something like:

$ cd path/to/john/run
$ ./dmg2john /path/to/your/image.file > image_hash
$ ./john -format:dmg-opencl image_hash (...)

Please note that for best results you should use a jumbo version no 
older than, let's say, this year - and preferably a really fresh one 
from GitHub sources.
