          Install dmg2img Install dmg2img.



          Next, read the package information page and the manual page to see if it is useful to you.



          The application seems to convert .dmg to a file that can be mounted using the mount command:



          dmg2img file.dmg imagefile.img


          From your Wikipedia article, the next command seems to be available to do that:



          sudo mount -o loop -t hfsplus imagefile.img /mnt


          In this way, the file imagefile.img is a result from dmg2iso and the contents will be available at /mnt. If the hfsplus type is not detected, you might need to load the kernel module for it:



          sudo modprobe hfsplus


          When done, you can unmount it by running:



          sudo umount /mnt

          • This will not work if the dmg file has 10.6+ compressed files in it.

            @tuxdna Do you really have a HFS image? Check the output of file file.dmg. You can also try 7z l file.dmg to list the contents.

          • I am using dmg2img v1.6.2. I ran dmg2img on mysql-5.5.28-osx10.6-x86_64.dmg which created mysql-5.5.28-osx10.6-x86_64.img, but it doesn't mount.

          To extract it, it is much more easier to use 7zip. Simply do:



          7z x file.dmg

            Thanks, 7z did the job, whereas dmg2img complained about a corrupted dmg image.

          This works for me:




          • Extract using 7z x

          • Locate the hfs partition file

          • Mount it to a directory

          • You can specify the single file you want to extract: 7z x ../mysql-5.5.28-osx10.6-x86_64.dmg 4.hfs

          If you succeed with the instructions from Lekensteyn and binfalse more power to you. If you are getting



          $ lsmod | grep hfs
          hfs 54782 0
          hfsplus 84912 0
          $ sudo mount -o loop,ro -t hfsplus imagefile.img /mnt
          mount: wrong fs type, bad option, bad superblock on /dev/loop0,


          Right now Ubuntu only comes with dmg2img version 1.6.2 and version 1.6.4 sometimes makes a difference. Also you can extract specific partitions from a dmg and only some of them are hfs+



          $ dmg2img -l file.dmg
          partition 0: Protective Master Boot Record (MBR : 0)
          partition 1: GPT Header (Primary GPT Header : 1)
          partition 2: GPT Partition Data (Primary GPT Table : 2)
          partition 3: (Apple_Free : 3)
          partition 4: disk image (Apple_HFS : 4)
          partition 5: (Apple_Free : 5)
          partition 6: GPT Partition Data (Backup GPT Table : 6)
          partition 7: GPT Header (Backup GPT Header : 7)
          $ dmg2img -p 4 file.dmg imagefile.img



          • Current Ubuntu versions come with 1.6.5 as of version 14.04

            When using dmg2img file.dmg imagefile.img on linux if you get
            ERROR: Inflation failed message, just install 7zip as



            sudo aptitude install p7zip-full


            and issue the following command on terminal



            7z x your_file.dmg



            • find the InstallMacOSX.pkg/InstallESD.dmg

            • issue the command dmg2img InstallESD.dmg imagefile.img on the terminal.


            Now you can mount imagefile.img with



            modprobe hfsplus


            and then



            mount -t hfsplus -o loop mountain.img /mnt

              First of all install DMG2IMG. Now you can convert it to IMG:



              dmg2img your.dmg new.img 


              The IMG can be mounted with:



              sudo modprobe hfsplus
              sudo mount -t hfsplus -o loop new.img /mnt


              And take a look at /mnt

                In the case of some .dmgs, you can neither 7z x them, nor mount the result of dmg2img.



                In that case, the .img resulting from dmg2img your.dmg new.img can have its paritions extracted with 7z x:

                                          In the case of some .dmgs, you can neither 7z x them, nor mount the result of dmg2img.



                                          In that case, the .img resulting from dmg2img your.dmg new.img can have its paritions extracted with 7z x:

                                          In the case of some .dmgs, you can neither 7z x them, nor mount the result of dmg2img.



                                          In that case, the .img resulting from dmg2img your.dmg new.img can have its paritions extracted with 7z x:
