Using a Mac OSX DMG Image in Windows and Converting to Standard ISO Format use dmg2iso

The dmg format is silly and annoying to work with, why couldn't Apple stick with the .iso standard?  Anyway, there's an excellent Linux and Windows based tool to convert it back to a normal .iso Image called dmg2iso

I'll only cover the Linux version although the Windows pre-built binary works the same way.

Download dmg2iso here for free (from the author's website)

It's just silly and doesn't make sense that Ubuntu doesn't have this in the repository at all, it's such a useful and almost essential tool.

For some reason I'm getting dmg2iso compile errors on my Ubuntu 8.04 install:

rm -f *.o dmg2iso.exe
gcc -O3 -c dmg2iso.cc

Instead I just downloaded the perl version.  Make sure you edit the .pl file to point to the correct path to the perl binary.  Also if you get carat M at the end of each line, remove the carat M on the first line or it will always complain perl does not exist.

 Unfortunately this tool didn't actually successfully convert the dmg image:

 

reading property list...found 6 partitions
decompressing:
partition 0
partition 1
partition 2

Conversion failed.File may be corrupted.

 

I also tried the trick of:

mount -o loop -t hfsplus file.dmg /mountpoint

but it didn't work

mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

And yes I did modprobe hfsplus and modprobe hfs with no luck unfortunately.

Use dmg2img instead of dmg2iso, dmg2img is the one that supercedes the dmg2iso

I just found this out, but I'm getting an error during make:

Make sure you install libbz2-dev and libssl-dev

Now it compiles and seems to be working unlike dmg2iso:
