Just a quick thought. Could you convert the DMG to iso then mount in osfmount?

Plenty of guides online on converting DMG files to iso.

Usually no.

The "dmg" format is used on MACs for both "disk" and "disc" images.

Most of the tools around will convert the latter kind, "disc" image to .iso (which is usually a "disc" image) but will give forfait on "disk" images (that would be in Windows ".img", i.e. "disk" images).

BUT this should work

FTK imager can open (add image as evidence) and extract from DMG images with underlying mac-based file systems. 7-zip can also extract files from DMG images.

DMGs can take on many forms. You likely have one of the formats that is not support by FTK Imager. A DMG can be one of these

UDRW - UDIF read/write image
UDRO - UDIF read-only image
UDCO - UDIF ADC-compressed image
UDZO - UDIF zlib-compressed image
UDBZ - UDIF bzip2-compressed image (Mac OS X 10.4+ only)
UFBI - UDIF entire image with MD5 checksum
UDRo - UDIF read-only (obsolete format)
UDCo - UDIF compressed (obsolete format)
UDTO - DVD/CD-R master for export
UDxx - UDIF stub image
UDSP - SPARSE (grows with content)
UDSB - SPARSEBUNDLE (grows with content; bundle-backed)
RdWr - NDIF read/write image (deprecated)
Rdxx - NDIF read-only image (Disk Copy 6.3.3 format)
ROCo - NDIF compressed image (deprecated)
Rken - NDIF compressed (obsolete format)
DC42 - Disk Copy 4.2 image
