darling-dmg

This project allows ordinary users to directly mount OS X disk images under Linux via FUSE. darling-dmg is part of Darling - http://www.darlinghq.org

Without darling-dmg, the only way to do this would be to manually extract the DMG file, become root and mount the HFS+ filesystem as root. This is slow, wasteful and may even crash your system. The project's author has seen the Linux HFS+ implementation cause kernel crashes.

Supported file types

DMG (UDIF) files containing an Apple Disk Image.
Apple Disk Images containing an HFS+/HFSX file system.
HFS+/HFSX file systems (incl. file systems embedded within HFS).

This means, darling-dmg can mount DMG files or unpacked DMG files or a single partition carved out of the latter.

Read only access only.
